We often mention Sing Core’s incredible strength and durability when talking about our door and wall panels, and we’re confident in that statement. As a customer, though, we understand that you may want more than just a promise in that regard, especially since our industry leading door and wall panels are so lightweight, they seem like they just can’t be as strong as the other options. Read on to find out why we beat out not only the competition, but full metal doors, as well.
What Makes Sing Core so Strong?
This is due to a few factors, the top of which being our patented honeycomb core that we use in almost all of our products. This wood and insulated core is designed in such a way that is incredibly strong, despite weighing a fraction of the other options. The interwoven lengths of wood provide a rigid structure that won’t bend, warp, or break. Plus, our doors are stronger pound-for-pound than steel. Then, our high quality insulation eliminates voids and protects against the harsh cold, sealing the warm air inside your home and helping to reduce your heating expenses.
While our honeycomb core is where the magic happens, we also laminate our panels with high quality wood to seal the core and add additional rigidity. By sandwiching our core between two high quality hardwood boards, we add another dimension of strength to our product. In addition, this provides impact resistance, as we don’t use cheap lumber like some of the other mainstream options. Overall, this provides a door or wall panel that can withstand tremendous force while still being so lightweight that it can often be lifted by one hand.
What are Some Other Benefits?
Sing Core panels receive other benefits from the strength of our cores, such as being 100% warp free. Due to our panel’s design, our products are guaranteed to never warp, and are protected by a 50 Year Structural Guarantee. If a door warps, many aspects of it and its function are lost or altered. For example, it may not latch properly, may form a gap, may distort the skin/finish on the door, may not open or close properly, and more. In addition to not warping, our doors are also incredibly impact and weather resistant. Kicking in one of our doors is more likely to break your foot than the door itself, and bumps, dings, and other forms of impacts won’t ruin or break through the outer panel. If, for some reason, your door does end up getting damaged, Sing Core panels are very easy to repair and return to full strength.
Why Should You Trust Us?
If we weren’t confident in the strength, durability, and integrity of our product, we wouldn’t offer a 50 Year Structural Guarantee. No matter what happens, if your door fails in any of the ways that we promise it won’t, we’ve got you covered. 50 years of promise means that we’re certain our door and wall panels won’t fail within that time, and even beyond.
Your front door is the gateway between your home, family, and belongings, and the outside world. Nowadays, it’s not enough to just protect your home from the elements, your door needs to provide safety and security for you as well. Sing Core’s new Security Door provides the same durable and high quality comforts you’re already familiar with, with added protection against intrusion.
What is a Security Door?
A Security Door is used to provide additional protection and peace of mind over what a standard door can do. Whether used as an exterior door, an interior door, or even a garage door, our Security Door can bring this added safety to your home or business.
Sing Core door panels are already incredibly strong, resilient, and guaranteed to last, and we stand by those qualities. However, intruders are constantly looking for ways to bypass the protection provided by traditional doors. These methods can include using anything from a chainsaw, to a circular saw, to an axe. While we trust in the strength of our standard core, with enough time and strong enough tools, even they can be cut through. With our new Security Door, that changes.
Why Choose a Sing Core Security Door?
Sing Core Security Door Panels come with our patented high-quality honeycomb core and rigid steel reinforcements. The honeycomb core provides insulation, strength, and sound-deadening features, while also remaining incredibly lightweight. By adding the steel reinforcements, we double down on the strength and durability of the panel, making it incredibly difficult to cut or break through. Plus, the door remains impressively light for the quality it provides.
A traditional door can be cut through in less than a minute, and while it would often make a lot of noise, these break-ins are often done when no one is home, meaning you won’t be there to catch them in the act. Cutting through a Sing CoreSecurity Door with the same tools would take substantially longer, and brings other challenges to the intruder, such being much louder, the likelihood of breaking a tool on the unexpected metal reinforcement, and a significantly higher chance of being caught.
In addition, these doors can be used in many cases aside from the standard front door scenario. Businesses with expensive equipment or sensitive documents may want to secure them in a more effective way, and luxury car owners may want a garage door that can’t simply be kicked in or cut through. You could even use Sing Core Security Panels to build a mobile and lightweight cabinet for on-the-go secure storage.
When it comes to your home, security is not an area where “good enough” is all you need. There are many ways you can improve the safety and security of your home, and installing a Sing Core Security Door is one of the most effective options. A break-in happens every 26 seconds in the United States, reaching 2.5 million break-ins every year, with over half being home burglaries. Let’s keep your homes and businesses off of that list.

What are the benefits of a Sing Core door?
What other benefits come with Sing Core products? Well, for one, they’re lightweight. This means that the hardware and framing used to install the door don’t take the regular wear and tear that comes with other products that are significantly heavier. In addition, our doors are impact resistant and warp-free, meaning they won’t be ruined by bumping into them, and they’ll never warp on you. The fully insulated core offers increased control over your internal climate and gives you the assurance that you won’t be surging your heating bill up by installing one of our doors. They’re also sound deadening, allowing for use in many other applications where sound may be of concern. Lastly, our doors are crafted with high precision techniques by master craftsmen, guaranteeing a consistent and reliable product every time.
What doors can I use Sing Core for?
Nearly all door types can be crafted using Sing Core technology. Pivot doors, sliding doors, garage doors, hinged doors, and many others. These doors can be used internally, externally, and for nearly any purpose. Check out these pictures of our product in use:
Summary
Deciding to renovate your home or office is a big step. Sing Core is here to make that process smooth and easy, allowing you to spend less time worrying about doors and more time designing your dream space. With Sing Core doors, you are guaranteed to have an incredible, durable, and long-lasting feature that will never fail, and you will never regret.
Sing Core has long been in the business of building the biggest warp-free doors in the world. And now you can learn how to build the biggest warp-free door as well. The first thing to note is that Sing Core does not build doors, even though Sing Core is credited and called out in architectural specifications as Sing Core door(s).
Inventor Peter Sing’s patent and patent-pending inventions are deployed in Sing’s Sing Core factory to provide the warp-free basis for high-end millworks and the biggest door companies for building big doors, over 8 ft. tall and up to 50 ft. or more, that can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.
New Door or Replacement Door
Sing Core assists in the building of either New Doors, doors that have not existed before, or Replacement Doors, doors that are being replaced and may have to be replicated to maintain the appearance of the original door, such as in the case of participating in a historical restoration.
How to Build the Biggest Warp-free Door
Since Sing Core does not build doors, it is up to the architect to imagine what size the new door should be and of what materials the door should be made of. In the case of replacement doors, Sing Core is provided all the specs based on the original door to be either replaced or replicated.
The following steps are followed in making a door with Sing Core inside:
Step 1: Answer questions, and estimate
What is the size (length, width, thickness) of the door?
How will you be finishing the door
What type of door hardware will be used (hinge, pivot, sliding, overhead, etc.)?
What style of door (flush, architectural, plank, French, Dutch, etc.)?
How and where will the door be used?
Will this be an interior or exterior door?
Are there other specifications (weight, insulation, sealing, etc.)?
Step 2: Re-evaluate and refer to Sing’s True Flat Team, if necessary
Evaluate your estimate and let Sing Core know if we can help meet your budget
The True Flat team is available to help you provide your customer with a door that fits within their budget.
Sing Core and the True Flat team can suggest ways of changing some of the details of the panel, such as, reducing the height/width or choosing a more cost-effective skin.
Steps might need to be made to modify Sing’s composite hybrid solid substrate to accommodate the challenges that may not have been noted in the original details gathered in Step 1.
Step 3: Manufacture specified Sing Core
The specific Sing Core substrate core is then manufactured in Sing’s factory by skilled workers who have been manufacturing Sing’s cores for years using Sing’s patented and patent-pending technologies. Occasionally, a new challenge is recognized that the true Flat Team has never seen before, that is when Sing get to inventing again, and when a solution is achieved, this will likely lead to another patented solution.
The core which is based on Sing’s insulated reinforced vertical grain torsion box core, may or may not be framed, and is sandwiched between two matching skins, ready to be used as door core.
If no other services are required, skip Step 4, and go directly to Step 5.
Step 4: Additional services
To further assist the millworks and door companies in the manufacturing process, Sing Core may provide other services. For instance, the millwork or door builder may elect to have Sing’s factory apply additional outer door skins to the completed Sing Core substrate, in a sense, creating a custom door blank.
Some of the additional services that Sing’s factory may provide, include:
Trimming
Adding exterior skins
Wood stave
Veneer
Cement board or concrete
High Pressure Laminate (HPL)
Fiberglass
Formica
Metal
Aluminum
Cold rolled steel
Copper
Galvanized steel
Hot rolled steel
Lead
Stainless steel
Impact/Bulletproof/Blast resistant materials
Light cutouts, openings, for glass inserts
Routing for architectural grooves
Step 5: Package and ship to millwork or door company
Sing’s factory packages and ships the door core or prepared blank to the millwork or door company who will finish the door.
Step 6: Finishing
Finishing takes place at the millwork or door company who installs hardware, finishes, and hangs the door, which is ready for installation.
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.

Meet Inventor Peter Sing
Besides all this, if you would like to know more about Peter Sing, the inventor and his creativity, click here. We have a four-minute video to give you an idea about how Peter Sing’s mind works. You should see it. Please tell your friends, because these inventions are needed.
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.
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.”
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.

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.
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.
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.
