Sing Core Now Available to Everyone

This may be the most important update from Sing Core ever.

Ever since the creation of lightweight, high strength, fully insulated, and warp-free Sing Core, inventor Peter Sing has sincerely desired to see this revolutionary material in the hands of the people, but due to the cost restraints of manufacturing a vertical grain small cell reinforced torsion box core, it was restricted to only high-end clientele who could take advantage of the technology.

13 foot lightweight panel strength peter sing core

Since then, Sing has invented many patented and patent-pending technologies to support these high-end architects, millworks, and door companies to make the impossible possible and still offer Sing’s unprecedented 50-year warp-free guarantee on door up to 50 ft or more.

Now, finally, Sing Core is available for you in the form of raw Sing Sandwich Core available from your local distributor.

This is good news for the thousands of craftspeople, engineers, furniture, and tiny house builders who have contacted Sing Core in the past and were disappointed with discovering that the cost was too high, or they were considered unqualified to handle such a raw substrate.

The Sing Core  factory only deals directly with architects, millworks, and door companies who have elitist clientele. This is still the case but now, Sing’s dream comes to life, as he can see his product reach the people who sincerely desire to use his technology in the real world.

There is no doubt that Sing’s reinforced insulated torsion box core invention is the most

Lightweight

High Strength

High Precision

Fully Insulated

Substrate in the World

Nothing else to date has been able to compare to Sing’s patented and patent-pending technologies in terms of weight vs strength, allowing architects and millworks to create lightweight works of grand size without compromising precision or performance.

Available via Your Distributor

If you are in the business, you already have distributors that you already deal with. Sing Core is now opening their most effective and popular product used by the best millworks in the United States of America to your distributor(s). So that the next time you place your order, you can simply add Sing Core to your order from the distributor that you already use, and they put it on the same truck that is delivering the rest of your products for use on your project(s). Now, it’s that easy. The product?

The Sing Sandwich Substrate

Raw, unfinished, and available in

4×8 or 5×10

This is hands down, the most popular, most powerful substrate in the world. With it you can build a structure or shelter without the need for framing,

create lightweight, insulated products of any kind,

anything from cutting boards to complete luxurious homes, and everything in between.

Keep in mind that the Sing Sandwich Substrate is raw and unfinished. It is for using as a full unfinished panel by itself, but will require trimming (as there will be exposed glue on the edges), but know this is the exact same bulk material that the most exclusive millworks use inside their creations that sell for thousands, or hundreds of thousands, of dollars.

One tiny house builder said he’d sell his tiny house built with this material for $5 million. Take a look at his $5 Million Tiny House.

Look at the many applications where you can apply the Sing Sandwich Substrate.

The Sing Sandwich Applications are nearly endless (see full list) as they are the secret ingredient inside the most expensive Building Applications and Components and it’s so versatile and easy to employ as long as you know How to Use Sing Sandwich.

Make a Table

You can use Sing Sandwich Core to make a huge table lighter in weight many times but stronger. Here’s some examples of tabletops with Sing Core inside.

This is why torsion box was originally used, but Sing’s invention takes torsion box to the next level by reducing the size of the grids, flipping the grain perpendicular, and reinforcing with rigid insulation, for incomparable compression and shear strength.

Replace Other Core Materials

We suggest cutting your Sing Sandwich Core into manageable pieces, say 1 ft x 1 ft squares, and insert into your own panel or product, cut to size, then hot or cold press between the skins you require. Just like you might use aluminum core, plastic honeycomb core, paper core, wood-based core such as LVL, interjoined wood, particle board,

Strong Hybrid Solid Composite Core

Plus, know that Sing Core is strong through and through, the voids inside honeycomb are left empty, Sing Core torsion box grids are not hollow, they are reinforced with rigid foam insulation to create a hybrid solid composite core.

Slice to Desired Thickness

You can slice Sing Sandwich Core to the thickness that you need (less the skin to be added) just like you might using a solid wood core material, then add another skin to recomplete the torsion box structure, and insert as substrate. You cannot do this with other cores as they will fall apart.

Caution: We also caution you against making anything oversized, like a 20 to 50 ft door. (See Don’t Try to Make a High-end Door below.)

Lower Price

Thanks to Sing’s new manufacturing method and subsidies provided by high-end clientele, raw Sing Sandwich Core can be manufactured at a lower price and is comparable in cost to other types of traditional core materials, so now is the time to contact your local distributor to as for Sing Core.

Empower Your Imagination

Simply buy bulk 4x8s, like the big boys do, as many as you need, cut to size and create whatever your heart desires.

Remember, Sing Core is not available from our factory, only directly from your local distributor, the 1 that you already deal with.

Do Almost Anything You Want

You can cut into smaller pieces, i.e. 1 ft x 1 ft for easy storage and inserting into anything that you want, though we caution against making anything too large. The Sing Core factory specializes in extravagant oversized projects that feature Sing Core inside, plus other supporting technologies, see disclaimer Don’t Try to Make a High-end Door below.

We Set Up Your Distributor

If they currently do not have Sing Core in stock for you, have them contact us. We will set them up, so that you can have full access to the Sing Core material you have so longed to use.

Sing Core for Everyone

This is a dream come true for inventor Peter Sing who has always wanted to see his material in the hands of every craftsman, artist, and manufacturer in the world. And now, thanks to the support of the most elite providers in the world and through this method of supplying the raw material to you through your favorite distributor, you can be using Sing Core in your projects, limited only by your own imagination.

Don’t Call Us

While we are so excited about being able to now offer Sing Core to the public, please accept our apologies in advance, as we do not offer customer support for consumers. We assume that you have the technical know-how and equipment necessary to use Sing Core responsibly, just like the professionals we supply. If you need to learn, there are many resources that can be found amongst the Sing Core website. See How to Use Sing Sandwich Core. Please feel free to check there for more information. If you feel you are in over your head, please find a professional millwork near you who can help you fix and/or finish your project to your satisfaction. By buying any Sing Core product, you do so at your own risk and accept full responsibility for doing so.

Don’t Try to Make a High-end Door (disclaimer)

You can probably use Sing Sandwich Core alone to use as substrate in a door up to 7 or 8 ft tall. A major part of what we do it to assist high-end door companies create doors of immense size that are guaranteed to remain true flat and warp-free for 50 years. While Sing Sandwich Core is found inside these huge high-end doors, it is not the only product you will find inside. Inventor, Peter Sing, has many patent and patent-pending technologies that are part of this large door segment, and his True Flat Team helps to engineer the hybrid and composite core inside these highly specialized door that lead to this level of performance. Factors taken into consideration besides the overall size of the door include but are not limited to, the surface material (skin), application, style (look) of the door, extra materials inside the door (interior blocking), how the door will be articulated (hardware), interior or exterior, location (geographic location, sea level, door facing direction, etc.), and usage, jut to name a few. Just as a word of caution that using Sing Sandwich Core alone will not result in a high precision and performance door, the type which Sing Core creates and guarantees to remain warp-free for 50 years. Please do not try this at home.

Alternative to Aluminum Honeycomb Panel

Sing Core’s alternative to aluminum honeycomb panel. aluminum honeycomb panel is used as core material in a variety of applications such as facades, walls, floors, ceilings, roofs, inside doors and partitions. Aluminum honeycomb core also found inside workbenches, craft tables, laser cutting tables, and a wide range of other types of work surfaces, especially when there is a desire to reduce the weight of the end product.

Increasingly, Sing Core is replacing aluminum honeycomb core with its Sing HPL Sandwich Core.

Sing HPL Sandwich Core

Sing HPL Sandwich Core is far superior to any aluminum honeycomb core in the following areas:

1.  Strength-to-weight ratio

2.  Fully insulated

3 High precision

4. Longevity

5.  Eco-friendly

6.  Warp-free

7.  Low cost

Sing HPL Sandwich Core serves as base core in many industries including government, scientific, universities, military, space exploration, aeronautics, nautical, in submarines, public transportation, railways, corporate, and industrial warehousing, just to name a few.

1. Strength to Weight Ratio

Sing HPL Sandwich Core exceeds all expectations when it comes to strength vs. weight thanks to inventor Peter Sing’s patented and patent-pending technologies which are the foundation for the success of Sing’s core. Long ago, Sing coined the phrase,

“Heavy does not mean strong, and lightweight doesn’t have to be weak.”

Sing’s invention changed the way architects and engineers brought their creative endeavors and problem-solving solutions to life.

2. Fully Insulated

Sing HPL Sandwich Core is a key ingredient in breach proof impact doors, and other applications where sound proofing, refrigeration, defense, and separation is imperative. Due to the nature and construction of Sing’s HPL Sandwich Core, no effort needs to be made to achieve an acceptable degree of sound deadening or climate control.

3. High precision

When the attention to detail demands high precision, no core material is more precise or stable than Sing HPL Sandwich Core sporting an impressive .006-inch tolerance. This is why Sing HPL Sandwich Core is hands down the go-to solution for dead flat tables supplied by the best high-end millworks in America today.

4. Longevity

When it comes to composite cores, risk is assumed in the area of the lamination process which holds the various products together over time. Sing’s patented and patent pending technologies eliminate the risk of delamination over the life of the product in use. And even comes with a 50-year structure warranty which includes delamination, so you don’t have to worry about it.

5. Eco-friendly

Aluminum Honeycomb Panels are made offshore and imported for use in the USA. Why? Because the production process is so toxic to the environment that it would be nearly illegal to manufacture in the United States. Even so, we still share the same air and oceans with our neighbors outside our borders. This matters to Peter Sing who only uses USA-sourced and natural materials holding the highest standards for Eco-friendly manufacturing methods for a better world.

6. Warp-free

Sing HPL Sandwich Core is long-renowned as, “the only way” to create large, panelized structure materials that will not warp under strenuous conditions. Though note that Sing’s True Flat Team must be involved in the engineering and manufacturing of the project because many factors must be taken into consideration to create a warp-free product, such as size, skin type, location, and application. Still, the only 50-year warp-free guarantee in the industry, regardless of size.

7. Low Cost

With the rising cost of aluminum and other metals, Sing’s Sing HPL Sandwich Core is a value in comparison to other manufacturing methods. You can now achieve greater results without having to use any metal, and saving money that would otherwise be wasted on metallurgy.

Other Types of Core Materials

Sing HPL Sandwich Core is vastly in the process of becoming the replacement core of choice over other types of lightweight core materials such as paper honeycomb, and different kinds of urethane core, EPS core, wood-based core, such as particleboard, LVL, solid wood core, as well as aluminum honeycomb core to keep the working subject straight, flat, or lightweight over time without fail.

Sing MDF Composite

Going a step beyond the Sing HPL Sandwich Core, one of the most popular hybrid composite products in huge demand is Sing’s MDF Composite available in core or panelized with solid wood edges and implants. This has the embedded HPL for all the high performance results, plus it is topped with a super smooth 1/8” MDF for easy painting or lamination of nearly any material.

Try it. You’ll love it, just like the rest of our high-end clients who rely on its stability and beauty when finished.

Standardized Surplus Special

In an effort to help spread the news about Sing Core’s ability to make most anything better, we have a way that you can try some Sign Core out for yourself.

We have a limited stock of Sing HPL Sandwich Core on hand in standard sizes that is taking up valuable space in our warehouses, so you are welcomed to try it out to see what you think.

Available Sing HPL Sandwich Core Surplus Items

We have some excess stock of Sing HPL Sandwich Core in the following sizes

4×8 4×10 5×8 5×10 5×12

standard 1 1/2, 1 3/8, 2 1/4 thick

Our standard thickness is 1 ¾ inch right now. But any size you can special order.

Quantities are limited to what we have on-hand.

These materials would be perfect for projects of nominal size, such as 2 ft, 4 ft, 5 ft, less than 3×5’, 2×6’.

Of course, if you want all the positive results of Sing’s core guaranteed 100% without worry, custom order from us. We will make you a frame, as featured in Sing Panels. Which means they come with solid wood edge, with the reinforced structure inside to keep it straight. That is more expensive but is trouble-free for you, for your door company, especially if you are dealing with very large doors. Some doors 8 ft 10 ft tall by 25 ft wide or bigger. This is our niche.

Otherwise, you can use Sing Core in endless applications, such as: See Application List

Sing Core MDF Composite

This is one very basic, less expensive option, but if you want to be straight, with concern of warping, or telegraphing, would require an upgrade with special skin underlayment beneath the MDF skin on top of Sing Core.

This creates a either a core material or full panel with stable material on both sides with MDF skin for paint grade or cold press purposes. More stable translates to less chance of telegraphing, and designed for high-end precision and smoothness. The price is a little bit over than that of standard MDF-only skin.

But, if you want to do hot press, then you must take advantage of our special hot press process. That means you can accommodate the increased high temperature and high pressure without worrying about any telegraphing. This is the most expensive method for the most demanding clients.

Note: We normally have a minimum order of $4,000 and orders under that amount are assessed a $500 surcharge. During this event for these items only, we are reducing the surcharge to $100.

Plug-in to Sing’s Core Group

As you become a regular customer you can achieve platinum status at Sing Core which plugs you into Sing’s Core Group. That means you get regular updates and training in all the latest news and developments that are happening here at Sing Core.

Platinum members may also be eligible for elimination or reduction of rush fees, when in a hurry.

$10,000 Doors

Doors with Sing Core inside can sell for tens of thousands of dollars due to the high precision and high quality.

If you are in the Core Group, you will access to all the training and knowledge necessary to qualify you to make $10,000 doors, too. And we’ll show you how to use the glue applied to make it stronger to last. As a platinum member, you will be a well-informed in any new technology developed by us.

So, this is the best opportunity for you to contact us. So, that means we can establish something in long-term relationship in support of your creativity because Sing Core has endless applications.

Secret Revealed: How to Keep Large Doors Straight

Inventor Peter Sing discloses how he and his True Flat Team can build enormous doors of any size and/or material and keep them straight and guarantee them to remain warp-free for 50 years.

 

First, there is the standard answer. Sing uses his patented torsion box hybrid composite core to build large doors that will not warp. Doors with Sing’s patented core inside are Eco-friendly, lightweight, high strength, and are fully insulated for increased temperature control and sound deadening capabilities.

How is it possible to build a large warp-free door?

This question is indicative of the problem facing door companies with doors over a standard height. If a door is over 7.5 feet tall, it is generally excluded from the warranty which might cover the rest of the doors in the build package. You will have to sign a waiver if they do decide to build the big doors for you, but it is more likely that they will have you get it from someone else.

 

Why?

Because they know there is the likely inevitability that those oversized doors are going to warp at the next change of season (or sooner) and they don’t want to be hassled with servicing the warped door.

How to Build a 50-year Warp-free Door

While the simple answer is to use Sing’s patented core, it is far more complicated than that. Peter Sing and his True Flat team have a toolbox full of patented and patent pending anti-warp technologies that they use on each large, oversized door, as no two huge doors are alike. Well, unless they are a pair of matched double door, then they are likely to be the same.

 

There are so many considerations that Sing and his team review prior to deciding how to build the door. First, it is the door’s dimensions. The bigger the door, the more engineering and warp-resistance needs to go into the door.

Then it is the door’s application. Will it be interior or exterior? Will it be exposed to the elements? If it is an exterior door, what area of the country will it be located? What altitude will it be installed at and which direction will it face?

Finally, what will the intended exterior surface material be made of?

 

The best parts are under the skin

Under the skin, the exterior surface material of the door, you will find a complex array of Sing technology fighting against the natural inclination of these big doors to move in response to any change in the local environment, including moisture, barometric pressure, heat, cold, just about anything you can imagine, Sing has a technology to keep that door straight.

In the most extreme cases, Sing’s team might be exposed to something new. A new unforeseen challenge, like wood grain’s reaction at high altitudes, or concrete in extremely cold temperatures. Necessity is the precursor to invention, which leads to another new patented Sing solution.

Then there are other considerations to take into account.

Are there any specific expectations such as final door weight, water, fire, sound, or bullet proofing? Impact resistance? Insulation R-value?

Every door with Sing Core inside is a work of art

As you may have guessed, a door that is going to be operated mostly in outer space (NASA) would be built quite differently from a door used in a submarine (US Navy). Just like an exterior front entry door made for Hollywood California would be different from a front door in New York City, even though they look the same and are made of the same basic materials.

Sing and his True Flat Team take all these things in consideration to make sure that the door you install today will not warp tomorrow, or anytime in the future (up to 50 years guaranteed).

This enables the biggest and best door companies in the world to build the biggest and best doors in the world complete with Sing’s 50-year guarantee.

It’s the only way to do it, and all you have to do is to contact your favorite custom door manufacturer or millwork near you and tell them you want a door with, “Sing Core inside,” and Peter Sing and his team will make sure you end up with a lightweight high strength warp-free door you can be proud to have for 50 years or more.

Hollywood News

End Your Warped Door Nightmare

A predominant actor has sold his $40 million dollar home and is moving across the continent to a penthouse suite. He loves the flat but the first thing he noticed was that the new 8 ft. tall doors were already misaligned and starting to warp. Unacceptable to this multiple academy award nominated actor whose star can be found on the walk of fame.

Sing Core to the Rescue!

All these doors have to go!” Sing Core is helping to create replacement doors that will aesthetically match the previous doors. “Admittedly,” says inventor Peter Sing, “we usually only get called on by the rich and famous to do big doors. I mean, 16 foot or taller doors. But in this case, we were summoned for 8 ft. tall replacement doors.”

As everyone in the door industry knows the standard 7 ft. tall door is the standard door height, which is determined by its warpability. According to AWI standards a ¼” warp is allowable and considered normal in a 3-0 7-0 door, and all door hardware is manufactured to take this variance into consideration.

Not so with doors that have Sing’s patented core technologies embedded inside. These doors are

Guaranteed Not to Warp for 50 Years!

Why do the biggest and best door companies, millworks, and high-end custom door makers seek out Sing Core?

Not only is it,

“The only way to build a large warp-free door,”

according to Sing’s long list of discriminating clienteles, but you also get a lengthy list of advantages from having a door with Sing Core inside. Such as,

Eco-friendly – Lightweight – High Strength

Fully Insulated – Sound Deadening – Increased Climate Control

Impact Resistant – Weatherproof – Sustainable

Even though they are so lightweight, only 2 to 3 lbs. per square foot, they are stronger than steel pound for pound.

As much as you might doubt Sing’s ability to deliver the goods when it comes to a 50-year warp-free guarantee? You know, if it wasn’t true, that would be the end of Sing Core, and for 20 years, the most important door makers of the most high end doors in the world depend on the patented Sing Core technology to do it. And to this day, they say,

“It’s the only way to do it.”

Shouldn’t you be doing it too?

Do You Have a Warped Door Story?

Sing Core has been helping the high-end door builders make warp-free super large doors for many years, and to date, not even one of them has warped.

One of the largest high-end door companies has been known to say,

“Since we started ordering large door panels from Sing Core, we have never had any problems with doors warping.”

Sing Core has endless applications… See Here

All doors made with Sing Core are structure guaranteed for 50 years, yet lightweight, 2 to 3 lbs. per square foot average, but if you try to breach the door, you will know it is solid as a rock, yet packed with insulation and sound deadening material.

Please tell your friends, especially if they are architects, millworkers, door manufacturers, or general contractors. They will thank you for introducing them to Sing Core.

Life is Short

The best you can do is to hope to leave something good behind, to try to make the world a little bit better than before you came, for your family, their families and the world at large.

Inventor Peter Sing has made his mark by introducing his patented invention of Sing Core to us which is changing the way big doors are made all around the world. One day the world will know that using Sing’s Core is the only way to build an Eco-friendly large door that will not warp.

The nearly unlimited possibilities of Sing Core boggles the mind, in the endless applications where Sing’s lightweight, true flat building material that is stronger than steel pound for pound could be used for anything from cutting boards, to entire homes built of Sing Core.

But there is no doubt, that Mr. Sing enables the biggest and best door companies to build the biggest and best doors in the world that can be guaranteed to remain

Warp-free for 50 Years

No other company can match Sing’s unparalleled high precision, performance, and longevity, guaranteed for 50 years.

See for yourself: https://www.pinterest.com/SingCoreOfficial

That’s what Sing’s clients say,

“There’s no other way to do it.”

And Peter Sing could not say these things about his true flat doors it if they were not true.

This is Peter’s legacy: To change the way things are made to last forever (or 50 years, whichever comes first).

How to Measure a Warped Door

How can you tell if you have a warped door or not?

There is an industry standard method of determining whether your door is warped or not.

To determine whether you have a warped door or not you will need a length of string (longer than the length or height of your door) and a measuring stick or tape measure.

a) Tape one end of the string to the edge of the door and the other end to the opposite edge of the door.

The string should be straight. If there is a gap between the string and the door’s surface, you may have a warped door.

b) Measure the gap between the string and the door’s surface area.

If the gap is greater than ¼” your door is warped (according to AWI standards for 1-3/8 to 1-3/4 inch doors 3’-0” to 3′-6″ x 7’-0”).

c) If the length exceeds 7 ft. AWI standard applies to any 7 ft. section. Apply string to any 7 ft. span.

Contact your door maintenance company and send them two photos.

d) [1] Photo of the length of the string which shows as much of the door in its entirety, or at least from one end of the string to the other. Then [2] a closeup photo of your measurement of the gap.

Armed with these two photographs, which can easily be emailed to the millwork or door maintenance company of your choice, the recipients will be able to determine how best to approach the repair or replacement of your warped door.

You might consider replacing your warped door with a professional door which has Sing Core inside which can be guaranteed not to warp, bend twist or otherwise fail so as to avoid this pitfall in the future.

For more information, see: Door Warping vs. True Flat

Storing SingCore Doors

After you’ve received your patented Sing products, if you will have to store them prior to finishing and/or installation, try to store them standing upright, on edge, with plenty of space in between, to allow air flow. Do not lean them against a wall. If you must store them stacked, wrap in plastic and place one or two sheets of plywood underneath and on top of the stack of Sing products. This will help keep the entire stack similarly acclimatized while not in use, otherwise, you may have to re acclimatize the top and/or bottom Sing products later, when you are ready to use them.

 

How to Store SingCore Doors

What if my door with Sing Core inside is warped?

The same standard method of determining and measuring any door with Sing Core inside is used just like any other door (as noted above).

Contact Sing Core about your concerns about your door being certain to include the two photos as noted above.

If you have purchased a professional door with Sing Core inside, you may be the recipient of a replacement Sing door.

Note that upon arrival and un-crating of a door with Sing Core inside, a door may appear warped (and indeed it will be measurable). This is normal for a door which has been packed and in transit. Stand your door on its edge at least twelve inches away from any adjoining surface area, allowing it to acclimatize for up to 72 hours. Measure your door again and you will find it to be straight and true. If not, document for warp (as above) and contact Sing Core.

In the event that a professional door with Sing Core inside is warped (which is highly unlikely) your help in determining the cause of the door’s warping is appreciated. Please assist documenting the chain of custody of your professional door with Sing Core inside, including the millwork or door company which finished the door, and the installers who installed the door, to help us insure your replacement door remains warp-free.

About Sing Core

SingCore panels are engineered with a lightweight, insulated, vertical grain tension box core. Then two skins are adhered to create a panel that’s lighter, stronger, and warp-resistant. Because the strength off our core doesn’t rely on wood, which is a naturally warping material, SingCore panels have a 50 year warp-free guarantee; the only one offered in the industry.

Additionally, SingCore panels are completely customizable, making them perfect for any project.

 

Dimensions

  • Length and Height are based upon your specifications to fit your project’s needs. We can also custom manufacture your panel’s grade, core grid size, skin type, edging, trimming, internal blocking, and thickness. However, the minimum thickness is 3/4″. There is no maximum thickness!

Edging

  • You can order Sing panels with open or closed edges. Ordering your Sing panels with open edges is useful if you intend to work with the panel post-manufacturing. If you prefer closed edges, the skin material will be pressed and glued over a solid wood frame. Unless specified otherwise, edging is 1.25″ solid birch.

Skin Options

  • We provide many different skin options to fit any of your construction needs. This includes Birch, MDF, Mahogany, Fir, Cedar, and even metals like Galvanized Steel. See images of example door skins on our Galleries page.

Trimming

  • Unless otherwise specified, all of our panels are shipped untrimmed. If you need a clean, finished panel on arrival, simply specify in your order. Open edged panels will always include trimmed edges.


Other Specifications: Internal Blocking and Embedded Chases

Many custom projects require specific hardware to be installed in our panels post-production. Therefore, we offer additional wood blocking anywhere within the panel. However, increased amounts of internal wood blocking will increase the weight and the likelihood of warping since wood tends to warp over time.

Custom Sing Panels can be manufactured to your architectural specifications, which may include special chases for plumbers to route hot and cold water feeds or electricians to run electrical wiring through. Since every Sing panel is custom manufactured, we can have your wire chase or plumbing pre-installed within your panels at any specified location.

For any special customization you need for your project, please provide us with detailed specifications and drawings so we can be sure to give you the product that you need!

Sing Door Ship Receive Warp-free Care

Shipping, Receiving, and Care of

Your Warp-free Sing Door

Sing Core only works with the best and most highly proficient millworks and door manufacturers. This segment of the industry is well-versed in how to deal with high-end building materials such as Sing Core. For many years, Sing Core has provided unfailing warp-free solutions to the biggest and best architects and millworks in the world, without one complaint.

As more millworks and smaller door companies are reaching out to offer their clients access to Sing Core, we do occasionally run across industry professionals who are not aware about what to expect or how to handle Sing Core raw materials. Some of these less-experienced, newer and/or smaller millworks and door companies may not know what to expect when dealing with a product like patented Sing Core. We desire to welcome newcomers to have access to patented Sing products. For those, we are providing the following information:

Unfinished

All Sing products are shipped as unfinished to the millworks and door companies who are highly proficient in working with high-end materials such as Sing Core. A Sing door blank is not a ready-to-install door and are not available from the factory with hardware or as pre-hung doors. Sing Core works in tandem with the industry professionals and the factory may, or may not, handle some of the detail works, such as applying exterior skins to the door blank. The door finishing, hardware, framing, and installation are all coordinated before your Sing door blank is built.

Packaging and Shipping

Sing products tend to be very large in size and require custom crating to assure they are not damaged in shipment to the industry professionals. Even with the best efforts of Sing Core’s custom crating team, sometimes a Sing product may arrive blemished and/or damaged by the shippers entrusted with the handling of crated Sing materials. In most, if not all, cases the level of structural integrity of Sing products in combination with the high level of proficiency of the finishers receiving Sing products, even damaged Sing Core can easily be returned to new condition, even if mishandled or damaged in shipment.

Arrival of Sing Products

Upon arrival of Sing products, be prepared to receive an unfinished product via truck. Offloading may require a forklift and dock for receipt. That said, there will be work that needs to be done to the product received by the millwork or door company before it is retail-ready.

Acclimatization

In most cases, when receiving a multiple Sing Core order, where Sing door blanks have been shipped in a stack, or side by side, it is perfectly normal for even a warp-free door blank to appear to be warped upon receipt. Usually, the Sing door blank(s) which face the outside of the crate, or the top of a stack of warp-free door blanks will appear to be warped. By acclimatizing these doors, they will straighten out to their straight and true flat appearance.

To acclimatize your Sing door core, stand your door on its edge at least twelve inches away from any adjoining surface area, allowing it to acclimate for up to 72 hours. Measure your door again and you will find it to be straight and true. If not, document for warp and contact Sing Core.

Storage

After you’ve received your patented Sing products, in the event that you will have to store them prior to finishing and/or installation, try to store them standing upright, on end, with plenty of space in between. Do not lean Sing products against a wall. If you have to store them stacked, wrap in plastic and place one or two sheets of plywood underneath and on top of the stack of Sing products. This will help keep the entire stack similarly acclimatized while not in use, otherwise, you may have to re acclimatize the top and/or bottom Sing products later, when you are ready to use them.

Door Warp Definition

Door warp is a variation from a plane surface within the door itself. It does not refer to the door in relation to the frame or jamb in which it was hung. Bow, cup, and twist are terms which describe warp in a door and are defined as follows: Bow is a curvature along the door height, or a deviation from a flat plane from end to end. Cup is a curvature across the door width or a deviation from a flat plane from side to side. Twist is a distortion in which one corner is out of the plane of the other three corners. Warp is usually a result of unequal stresses within the door from one face to the other caused by changes in humidity and temperature conditions or uneven conditions from one face to the other. Buildings shall be humidity and temperature controlled before doors are delivered and installed. Required conditions are 25% to 55% relative humidity and 50° to 90° F (10° to 32° C) temperature range. Improper handling, stacking, and storage can also contribute to warp. Doors shall be stored flat on a level surface off the floor with cross supports.

HOW TO MEASURE WARP

Use a taut string or straight-edge and measure on the concave face of door – diagonally, horizontally, or vertically. Measure at the point of maximum distance between the taut string or straight-edge and the face of the door.

Measurement must be made on the concave face of the door. Door shall be open when measuring for warp (lock not latched into strike). One person can measure warp using a string and taping one or both ends onto the face of the door, holding it taut. Don’t measure warp in relationship to the door frame. Often a door may not fit into the frame properly but is not warped. In these cases, check the frame – it must be set plumb and square and jambs must not be twisted or out of alignment. Action on any claim for warp may be deferred for up to one year after project completion to permit doors to acclimate to temperature and humidity conditions.

 

ALLOWABLE WARP TOLERANCE
FOR WOOD DOORS

1-3/4 inch (44 mm) or thicker doors:

  • 3’-6” x 7’-0” (1050 mm x 2100 mm) or smaller, 1/4 inch (6.4 mm) maximum.
  • Larger than 3’-6” x 7’-0” (1050 mm x 2100 mm), 1/4 inch (6.4 mm) maximum in any 3’-6” x 7’-0” (1050 mm x 2100 mm) section.

1-3/8 inch (35 mm) doors:

  • 3’-0” x 7’-0” (900 mm x 2100 mm) or smaller, 1/4 inch (6.4 mm) maximum.
  • Larger sizes not addressed in this standard

Warp-free definition: Doors with patented professional SingCore inside outperform any other Eco-friendly door in the world in terms of being lightweight (SingCore weight is approximately 10 % of solid wood, timber or plywood core) and high strength (660 PSI+, stronger than steel pound-for-pound). No other door Eco-friendly door made in the USA can reach our high precision (SingCore approximately +/- .006 inch) or flatness meets or exceeds door industry allowance for door warp, as seen above). We guarantee no other Eco-friendly, lightweight, high-strength insulated door can compare with any door that has patented professional Sing Core inside. SingCore is raising the standard of what is possible in terms of building large doors that can be true flat and warp-free.

How can you tell if you have a warped door or not?

There is an industry standard method of determining whether your door is warped or not.

To determine whether you have a warped door or not you will need a length of string (longer than the length or height of your door) and a measuring stick or tape measure.

a) Tape one end of the string to the edge of the door and the other end to the opposite edge of the door.

The string should be straight. If there is a gap between the string and the door’s surface, you may have a warped door.

b) Measure the gap between the string and the door’s surface area.

If the gap is greater than ¼” your door is warped (according to AWI standards for 1-3/8 to 1-3/4 inch doors 3’-0” to 3′-6″ x 7’-0”).

c) If the length exceeds 7 ft. AWI standard applies to any 7 ft. section. Apply string to any 7 ft. span.

Contact your door maintenance company and send them two photos.

d) [1] Photo of the length of the string which shows as much of the door in its entirety, or at least from one end of the string to the other. Then [2] a closeup photo of your measurement of the gap.

Armed with these two photographs, which can easily be emailed to the millwork or door maintenance company of your choice, the recipients will be able to determine how best to approach the repair or replacement of your warped door.

You might consider replacing your warped door with a professional door which has Sing Core inside which can be guaranteed not to warp, bend twist or otherwise fail so as to avoid this pitfall in the future.

For more information, see: Door Warping vs. True Flat

What if my door with Sing Core inside is warped?

The same standard method of determining and measuring any door with Sing Core inside is used just like any other door (as noted above).

Contact Sing Core about your concerns about your door being certain to include the two photos as noted above.

If you have purchased a professional door with Sing Core inside, you may be the recipient of a replacement Sing door.

Note that upon arrival and un-crating of a door with Sing Core inside, a door may appear warped (and indeed it will be measurable). This is normal for a door which has been packed and in transit. Stand your door on its edge at least twelve inches away from any adjoining surface area, allowing it to acclimatize for up to 72 hours. Measure your door again and you will find it to be straight and true. If not, document for warp (as above) and contact Sing Core.

In the event that a professional door with Sing Core inside is warped (which is highly unlikely) your help in determining the cause of the door’s warping is appreciated. Please assist documenting the chain of custody of your professional door with Sing Core inside, including the millwork or door company which finished the door, and the installers who installed the door, to help us insure your replacement door remains warp-free.

What to Expect from Sing Core

What can I expect to receive when I order Sing products?

Sing Core only ships authentic Sing products to millworks and door manufacturers. Why? Because Sing products are raw building materials in unfinished condition. You cannot order a completed Sing door from Sing Core. Even though we are renowned the world over for the best doors, our web site clearly states,

“We do not build doors,” we only supply the best millworks and door manufacturers with the best professional door slabs which can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

See also, What We Do: http://singcore.com/education/what-we-do

Don’t you have a standard Sing door?

No. Every custom door we build is like a one-of-a-kind work of art, though we are able to build many of the same type/style/size of doors at the same time, which can reduce pricing if purchased in bulk.

Don’t you want to make Sing Core available to the world?

Yes, we do, but remember, Sing Core is shipped in an unfinished condition and therefor is not ready for public consumption. It would be similar to ordering a 20×40 concrete slab, then being upset when the concrete truck shows up because you wanted a completed slab, not wet concrete. (The contractor knows what’s going on, but it might be a shock to the contractor’s customer.)

Isn’t Sing Core available in retail locations, like Lowe’s?

Yes, and no. We only ship to locations which have a full millwork shop inside to adequately finish the Sing products for their clientele. If the retailer does not have a full millwork shop for finishing Sing products, we will not intentionally ship unfinished product to that location.

What if I’m a contractor and my client wants Sing Core?

No problem, we will ship directly to your millwork, or the finisher of your choice. Once the Sing products have been finished, they can be installed by your installers.

How does architectural specification affect our bid?

If you’re a contractor bidding on a project where Sing Core has been specified, note that your quote from Sing Core is for unfinished materials. For instance, if a 20 ft x 10 ft x 4 in pivot door with birch wood stave has been architecturally specified, you will only receive the unfinished door slab with the appropriate interior supports for the hardware specified. You will still need to have the slab finished and prepped for hardware by your millwork, you will also need to source and price hardware, and account for framing and installation to complete the job.

What if my warp-free products show up warped?

Professional millwork companies know it is common for panels to display some warp when unpacked due to being crated and transported. It is the nature of raw materials which are packed, and traverse varying climate conditions while being shipped. Acclimatization of Sing products (separating them, standing them on edge for 72 hours, and allowing them to acclimate to your climate will allow the products to return to their true flat condition).

What if my Sing products are defective?

In the event that your professional Sing panels are warped beyond AWI standards, or the architectural standards as notated by your work order, you may have a defective Sing panel. Working with our warranty department will help to determine if you have a defective sing panel. If so, Sing Core will fix, repair, or replace the defective panel to assure its architectural integrity.

Know What You’re Getting

We at Sing Core want you to know what you’re getting, wo that you can be prepared to enjoy the best Eco-friendly lightweight/high strength raw building material available and achieve its maximum potential and elegance.

Sing Core Definition of Terms

Acclimatization

Sing Core panels acclimatizing: According to the type of the skin. Aluminum, metal, plastic skin, concrete, and ceramic skin will be delivered in perfectly straight condition without any acclimatizing. Plywood, hardboard, and HPL will take much less time to acclimatize than MDF. The best way to acclimatize is stand panels on edge with 4” or more of equal spacing between each panel.

Eco-friendly

Contrarian Sing Core purports to introduce a new degree of Eco-friendliness in sustainable building materials, not expendable and disposable import products which dominate the present day architectural landscape. Sing Core is ecologically conscious throughout its Made in the USA manufacturing process. The factory expends very little energy, local manpower, to manufacture Sing Core which is built from the smart use of a combination of natural wood resources, insulation and formaldehyde-free adhesives in the non toxic manufacturing process of the sustainable lightweight and high strength building material designed to last for centuries.

Edges

Edges of Sing Panels can have a variety of options. They can be open-faced (no edges) which means the patented Sing core material would be exposed and visible from the edge, between the two surface materials (skins). Edges can be embedded and pre-sealed between the surface skins per specification. Standard edging is 1.25 inches solid wood. Edge-banding is commonly applied by millwork or other finishing agent.

Embedded Chases

Chases or channels for cable, electrical or other services (such as water) can be pre-installed to specifications during the manufacture of your Sing Panels. Contact your Architect or Sing Representative to make certain your embedded chases are manufactured to meet your needs or specifications in advance.

Grid Size

Due to the specifications and requirements of your Sing Panel or door substrate the size of the wood torsion box grids inside can be adjusted to fit your needs or performance expectations. Three sizes of torsion box grid size are available. Small grade: 2×2 inch grids. Medium: 2×3 inch grids. Large: 3×3 inch grids. Default size is 2×3 inch unless otherwise specified. Check with your Architect or Sing Representative to make sure you have the right structure grid size for your project.

High Strength

Even though extremely light in weight compared to other lightweight honeycomb and/or substrates, patented Sing Core was independently tested for structure strength and rated at 660 PSI (which can achieve higher ratings, if necessary for your specs) making it stronger than steel pound for pound. Other lightweight materials have structure strength of 10 to 110 PSI. This is what gives patented Sing Core its stellar reputation for high strength with little or no deflection over long spans with little substructure.

Insulation

The otherwise left empty voids in traditional torsion box is filled with rigid insulation material which serves as rigid material which shores up the vertical grain torsion box walls imbuing patented Sing Core with its unparalleled structure strength, while adding insulation qualities of climate control (R-value) and sound deadening (STC-rating*) attributes. The insulation used inside the Sing Core torsion box structure grids can be altered to meet architectural specifications and/or performance expectations.

Internal Blocking

Internal blocking or solid implants can be strategically placed inside your Sing Panel or door blanks per your specifications. Please double-check your specs prior to having your Sing Panels or door blanks manufactured.

Large Door

Where Sing Core shines in the door industry is in the ability to provide a lightweight high-strength door blank to door manufacturers and millworks for doors over 7 ft. tall and 3.5 ft. wide that will not warp. Solving not only issues associated with door warp, but also minimizing the weight of large doors without compromising strength. How large can a door be with Sing Core inside? Sing Core can build large door blanks in nearly any size up to 50 ft. tall and/or 50 ft. wide, or more.

Lightweight

The average weight of a Sing panel is 1/2 pound to 2 pounds per square foot. Weight is determined by many factors including torsion box grid size, rigid insulation material and glue used as well as other components of the panel’s composition including patent pending professional warp-free stiffeners, surface materials (sins) and adhesives used in the manufacturing process. Your architect or Sing representative can present you with a projected weight estimate prior to manufacture.

Paint Grade

We deliver your panels as unfinished “paint grade” as opposed to paint ready. Under normal circumstances, Sing panels and door blanks are provided as paint grade to millworks and door manufacturers who prepare the surface area for paint if necessary or required. If you require paint ready Sing panels or door blanks be certain to specify expectations prior to manufacture.

Post and Beam

Post and beam is only represents the depiction of a specific dimensional characteristic of an otherwise normal Sing panel, where its dimensions dictate the proportions and function of it as a post or beam. When used as posts and/or beams, Sing Core offers unique advantages over traditional wood and/or metal posts and beams.

Professional Grade

Professional grade panels can be guaranteed warp-free for 50 years. Composite stiffener technology is integrated with the structural core, which prevents warping and provides a truly flat panel. Professional grade panels provide a 50-year non warp guarantee when used in appropriate applications.

RSIP

A Sing panel is classified as a Reinforced Structural Insulated Panel (RSIP) due to its underlying reinforced torsion box grids which is the heart and soul of patented Sing Core.
Sing Core

Patented Sing Core is the key to the success of Eco-friendly, lightweight, high-strength Sing products. The specifics of the design features small (2 inch to three inch) vertical wood grain torsion box grids where the voids (which would otherwise be left open) are filled wall to wall with rigid insulation material. This core material is sandwiched between two surface skins and may (or may not) be framed with wood or an alternate framing material inside the exterior stress skins.

Sing Panel

A Sing Panel consists of a substrate of patented Sing Core sandwiched between two stress skins of any available flat building material which may or may not feature exposed edges or closed (framed edges).

Size

The dimensions determining the size of any patented Sing product are determined by architectural specifications and include: length or height x width x thickness (in inches). These dimension are necessary for a preliminary price quote.

Skin

Skin refers to the flat building material that acts as the stress skin for completing the reinforced torsion box design. While the core supplies the vertical torsion box walls, the exterior stress skins seal the top and bottom of all interior boxes. Skins can be made of any flat building material including any available species of natural wood, aluminum, concrete, fiberglass/FRP, Kevlar, LVL, MDF, Metal, Steel, etc… These skins are adhered in an Eco-friendly manner using formaldehyde-free glue, cold pressed with very little energy expended and little no toxic fumes or unnecessary waste.

Standard Grade

Standard grade panels utilize our patented torsion box core and provide unparalleled strength and lightweight properties unachievable with traditional building materials. Standard grade Sing Core is not guaranteed to any degree of flatness, though easily out performing any AWI allowed variance in warp for a door which is considered to be flat. AWI allowance equivalent to ¼ inch along the greatest distance for a standard sized door. There is no expectation for warp resistance for large doors (doors over 7 ft. tall).

Storage and Protection

Store your Sing Core door in an upright position and allow to acclimate to room temperature following shipment receipt or prior to finishing or installation.

Strength of Sing Core

The strength depends on the thickness of the panel. For instance, if you double the thickness it will be 4 times the strength. The thickness of the skin could make up the extra strength but increasing the thickness to gain strength will result in added weight, which may compromise the end result. The answer is usually a combination of matching the right Sing Core width with the appropriate surface material to achieve the desired results without loss of structural integrity or unnecessary additional weight.

Structure Warranty

The structure warranty that accompanies professional grade or hot press ready grade Sing panels or door blanks warrants your Sing product against structure failure. Also ensures that your Sing products are not disposable, are reusable and can easily be repaired if damaged, often on site without disassembling using regular woodworking skills and tools.

Thickness

When Sing Core representatives reference the thickness of a Sing panel or door blank, it generally includes the thickness of the Sing Core insulated reinforced torsion box core, as well as the thickness of the exterior surface materials (skins) included.

Torsion Box

Sing Core’s patented torsion box design is a significant improvement on the torsion box design which has been used in traditional wood working. In Sing Core’s patented design the torsion box grids are not made with horizontal grain wood, it is instead flipped on its side so that the grain runs vertically (up and down instead of sideways) and the size of the individual boxes are small (2 to 3 inches). The voids, which are left vacant in traditional woodworking torsion box structures, are filled wall to wall with structurally rigid insulation and this substructure is sandwiched between two skins of plywood or any other applicable sheets of flat building material to complete the composite panel.

Trade Professional

Sing Core only supplies their patented material to trade professionals, like architects, cabinet makers, millworks and door manufacturers. Sing Core does not offer materials for retail. If you are a home owner who desires to have Sing Core products incorporated in your home, contact your local trade professional (architect, contractor, builder, cabinet maker, manufacturer or door company) for more information. As you know, we do not ship finished materials and only ship to authorized finishing facilities (millworks) who are responsible for finishing your Sing products. These are the people that make us look so good.

Trimmed / Untrimmed

The default condition of Sing products is normally untrimmed. This means your sing products will arrive at your millwork or finisher with unfinished, untrimmed edges and exposed glue may be visible from the edges of the Sing panel or door blank. Alternatively, your Sing panels or door blanks can be trimmed by request, leaving a clean, smooth finish on the edges. Allow ¼ inch for trimming, if requested to be completed prior to shipping from Sing Core. Be certain to specify “trimmed” when ordering your Sing products, as they will have to be build oversized to allow for the ¼ trimming.

True Flat

True flat is what Sing clients have referred to Sing products as. It is not an industry term, but it did become common vernacular in reference to Sing products which outperform any known lightweight, structurally strong product in terms of flatness or lack of deflection under load and among long spans. True flat is considered proprietary nomenclature and does not have a scientific definition or industry-wide classification because nothing compares to Sing Core in terms of Eco-friendly, lightweight and high strength.

Turnaround Time

The standard turnaround time for Sing products is approximately four to eight weeks, so take this into consideration when you are ordering your Sing products. In a hurry? Check with your Sing representative, rush service may be available for an additional fee.

Unfinished

The standard condition for delivery of Sing products is, “Unfinished.” That is to say Sing products are not manufactured to be an end-sale product. Sing Core’s standard method of operation includes wholesaling and shipping Sing products to millworks, cabinet shops, finishers or door manufacturers who complete the process and ready the items for installation or resale. Sing products are not retail-ready and not available directly to consumers.

Warp-Free

Warp-free is the Sing Core promise for the condition of professional Sing panels which are built for specific purposes and high precision expectations. Professional grade Sing products are a concerted effort of the designers , architects and the True Flat team at Sign Core to create a Sing panel or door blank that will endure the environment and circumstances facing the regular use of said panel or door over a 50-year lifespan. A professional Sing panel built to these specifications and used for its prescribed conditions can be delivered wit an accompanied hard copy signed certificate insuring the product to be guaranteed to remain warp-free for 50 years.

Wood Stave

Wood staves (a narrow length of natural wood “stave” with a slightly beveled edge) can be utilized to form the exterior of Sing Core panels or door blanks. These can be used to replace other types of solid wood building materials. Natural wood stave species are subject to availability. Standard wood stave exterior measures 1/8 inch and is available in other thicknesses according to architectural design and specifications.

 

* Note: STC rating varies according to size, thickness, skin, and other factors. Sing Core does not rate doors, although we are fortunate enough to have one of the best sound testing labs in the world, here in the Pacific Northwest. If you require a specific STC rating, Sing Core can build a door to your architectural specifications and have the resulting door tested at our rating facility for an official rating.
