Applications -> Building Components -> Doors -> Architectural Door Specs

General Specifications

Standard Sing Core doors are manufactured with patented Sing Core material as the base interior substrate of the door. The Sing Core substrate material is created using a vertical grain natural wood torsion box design while the traditionally empty voids are filled wall to wall with recycled foam. The foam material is available in various forms depending on your specification. The default is recycled EPS foam. Natural wood lock blocks are positioned at locations as necessary for locking mechanism placement or as anchor points. The core material is wood framed by 1 ¾ “ natural wood for finishing strength and attaching hardware. The torsion box is completed by adhering an exterior material (skin) according to your specifications. The default is a wood-grain (Luan) material. Bonding agent used in adhesion of the entire composite material is formaldehyde-free.

How to Build a True Flat Wood Door

10×12 ft 3″ thick warp-free 1/8″ oak 520 lbs

True flat technology is based on expertise in building any door that can be guaranteed true flat and stay flat. This composite science includes the proper proportions of Sing Core, aluminum and/or other materials and bonding agents based on your requirements or specifications. In this way each Sing door is a work of art.

One of the challenges in building any wood product of any dimension where the customer desires a perfectly flat surface over long spans is insurmountable in many circumstances.

This is the proven niche specialty service provided by Sing Core to the worlds most high-end, demanding, high-profile millworks and end users for years. Due to the unique properties of the patented Sing Core material, true flat designs can come to life and deliver superior satisfaction while carrying a 10 year structural guarantee.

AWI standards may allow for a certain amount of deflection over long spans, the patented Sing Core material far exceeds deflection allowances of other materials, due to its torsion box design while remaining true flat.

This is why the most prestigious millworks in the United States turn to Sing Core for their large, oversize doors, though they have the added benefits of having an end product that is:

Eco-friendly
Renewable
Dimensionally stable
Extremely Strong
Light weight
Insulated
Sound deadening
Easy to machine

And could be customized to include:

Waterproof
Fire retardant
Bullet-proof
Any Thickness
Almost unlimited skin options
Fast turnaround

The True Flat Challenge

The true flat door is a challenge for architects, door manufacturer, millworks and general contractors, especially if the door is 1 inch thick (or more), over 8 feet wide and/or 16+ feet tall.

If you’re looking for the answer, you might Google search how to build a true flat door.

Oversize doors present the biggest challenge for true flatness, but they also present other issues that must be dealt with in high end homes and/or commercial applications in terms of weight and strength. Again, let’s see what Google has to say about lightweight high strength true flat?

The clear answer is Sing Core; a new invention of material that is playing a major role – not just in building large doors – but almost anything that requires (or desires) to be Eco-friendly, functional yet elegant for inside/outside a home or in building and construction that needs to be light, strong and sustainable

Aluminum composites are common in the aerospace industry, but are cost prohibitive and not user-friendly for mill working or broad earth-bound use. Sing Core is designed to be used in millworks and does not require any specially-trained labor or specialized equipment; treat it just like you would any other standard wood-based substrate material.

Sing Core’s true flat process utilizes vertical grain torsion-box/foam-core/aluminum composites to deliver the solution. Contact us for more information, and if you like, we will show you how to integrate this new technology into your operation.

Meeting the Highest Demands

We maintain the highest degrees of integrity when meeting the requirements of our clients, and their customers, assuring complete satisfaction. Most importantly, proper communication is the key. If you have certain expectations – and you let us know – our team can deliver the product that matches your specifications.

Simply by providing us with your dimensional requirements:

height
width
thickness

along with what your preference for visual presentation (exterior skin material) and performance expectations are, we can provide you with the solution to best suit your application.

How Do We Do It?

When you explain to us what your expectations are, we know how to create the product that meets or exceeds your expectations. For instance, if you require a 17 foot tall oak pivot door that is true flat.

First of all, if the pivot door were solid oak, it would fail the standards test due to the raw material. Natural wood will warp, twist and crack if left to itself. Not to mention being heavy in weight. The excessive weight is an added strain on the integrity of the structure and hardware, increasing maintenance costs over time.

Our designers will likely prescribe a solution that begins with a Sing Core base material in the center which is by itself perfectly flat. Adding oak wood staves is where the problem comes in; because natural wood is unstable and will compromise the overall structure. To combat this issue, our team may fuse the Sing Core material to aluminum to complete the substrate composite. Then, when the exterior oak faces are applied to the structure; like magic, the result is a lightweight, super strong solution that can be perfectly flat.

The resulting Sing Core lightweight solution does not compromise the structure or the hardware eliminating expensive repairs and/or maintenance.

That’s just one example. Some of the materials used in our true flat composite resolutions that battle the temperature and moisture weaknesses that accompany utilizing natural components (like wood) include

Our lifetime of experience dedicated to solving the challenges of architects, designers and craftsmen who serve the most prestigious clientele, especially in terms of sustainable, lightweight, super strong and true flat solutions that maintain structural integrity over many years, while retaining the beauty and elegance of natural wood (or any other desired external material).

Metal is used across many industries. Metal honeycomb composite is the leader in honeycomb cores used to create stronger and lighter metal panels as well as posts and beams using much less solid metal.

Sing core is the leading technology of metal honeycomb composite material that solves our future Eco-friendly energy solution by using Sing metal honeycomb composite at a fraction of the weight of solid steel, but is stronger, lightweight, and available in steel plate, steel beam and steel panels.

Tell the US Energy Department to do some home work and research the Sing solution. If you believe Sing Core will help us use less metal thanks to Sing honeycomb metal.

Case study #1: Do not waste more precious metal if you could use Sing Metal honeycomb panel, post and beam.

Replace steel by using Sing 13 ft x 3 ft x 1 inch Sing honeycomb metal plate for use in conveyor.

1 Advantage: Precision true flat – within thousands of an inch – the majority of metal fabrication relies heavily on welding that causes the metal to deform. Sing metal uses structural glue, nuts and bolts instead of welding metal plates onto the steel frame which takes more labor, energy and end the product will not match the same precision as Sing Metal honeycomb panels.

2 Easy to fabricate and install – lightweight metal is safer to process, costs less to transport and uses less labor to install.

3 Less cost: Solid metal takes many times more metal than Sing Metal panels, posts and beams. It is expensive to transport, takes more energy to process and the most important thing is that Sing Metal is much less expensive than solid metal planks or sheets. If the strength, lightweight and Eco-friendly attributes are considered you may never go back to solid metal again.

Case study #2: If your seeking to improve your products with greater precision, true flat doors or panels, walls, floors, ceilings, RVs and/or boats then we’d like to teach you to Sing.

This is the latest technology to build true flat doors. If we are able to build a true flat door then you can believe that we could make true flat floors, ceilings, walls, etc… all lightweight, high strength, long lasting and endless benefits just by Singing with us.

Doors are a challenge for door manufacturers and mill works if the door is over 8 ft in length and less than in inch thick.

One of the Sing aluminum honeycomb panels are used as door substrate. It used in almost all major high end residential and commercial door applications due to the true flat characteristics. AWI standards for true flat include deflection of ¼ inch, which is unacceptable for Sing Core. We can minimize deflection to 1/8th or even 1/16th according to your pre-arranged specifications and application requirements to ensure satisfaction.

But if you have a door over 12 ft – even over 16 ft tall – and less than 1.5 inch in thickness and you are wishing to have the least deflection than you need to contact www.singcore.com to find the true flat solution which is use aluminum panel as substrate than add MDF or AB plywood for paint grade door or by cold or hot press to add finish veneer to build the most beautiful, strong, lightweight eco friendly door.

Doors made of Sing Aluminum honeycomb substrate do not need to acclimatize due to there being no moisture difference on either side of the door substrate.

Sing Aluminum honeycomb door substrate can be machined or drilled just like wood without retooling or damaging your blades. It is easy to glue with proper clean up procedure.

Large over size doors for high end building project require the true flatness. Patented Sing Core is the ultimate solution for high end mill work across the country.

Torsion Box

Torsion box design in woodworking is basically a number of wooden boxes assembled together to make up the core material sandwiched between two sheets of wood. This is a labor-intensive process for craftsmen, but does produce a lighter-than-solid-wood product that has increased strength due to the torsion box interior.

Click for How to Buy Torsion Box Sandwich Panel

Craftsmen have been using torsion box for centuries, but it takes a skilled craftsman hours if not days to create a table… Sing Core provides craftsmen with the torsion box structure pre-built. Doing so allows you to make 50 times more tables or 100 or more Sing Torsion Box 2 in x 12 inch x 8 planks in a single day. Wood products made of patented Sing Torsion Box lumber, panels, posts or beams can be easily mass produced in a small work shop without adding any heavy wood working machines. The labor-saving and high-quality will make it possible to bring the furniture making jobs back home, creating jobs and improving local economies while reducing the impact of imported furniture.

Inventor Peter Sing has taken torsion box technology to the next level, making massive improvements to the primitive, yet effective, torsion box design.

Sing Improvement # 1: Flip the script.

The first improvement on the traditional torsion box design was so simple that it was merely, “a gift,” as Sing explains. Torsion box grids have always been an effective way to produce a large wooden surface, while retaining some integrity of strength and resulting in a lighter weight end product. “But,” says Sing, “the wood material used to construct the torsion boxes always used horizontal grain.” By reorienting the grain to be vertical, the resulting torsion box became 10 times stronger than the horizontal grain original designs, but he wasn’t done, yet…

Sing Improvement # 2: Fill the void.

The next step was to fill the void with a stable, yet lightweight, material. Recycled foam was the answer. By filling the vacant space in each cavity of the torsion box, edge to edge greatly increased the strength of the torsion box, as well as adding insulation and sound deadening properties, without adding much noticeable weight increase.

Sing Improvement # 3: Fuse the structure.

The final step in Sing’s revolution in torsion box design was to develop a method to bond all the necessary components together resulting in a nearly indestructible, yet solid, lightweight structure. Experimentation led to discovering superior bonding agents for superior adhesion that will not breakdown due to stress on the structure or over time… and this was achieved without the use of formaldehyde or toxic chemicals.

The result is a natural torsion box design combined with recycled materials that could be used as a substrate for nearly any building material, making Sing Torsion Box the composite material of the future.Sing Core is also Eco-friendly, “True green,” Sing calls it because it is all manufactured naturally, with little energy consumption, uses recycled materials with little or no waste. It also reduces the greenhouse effect in fuel expended in the delivery of the material due to being so lightweight. Manpower reduction is also an effective savings due to its lightweight characteristics.

Sing Core is proudly manufactured in the USA in McCleary, Washington, and due to its lightweight attributes can be shipped to any location on Earth at a fraction of the cost of other, traditional solid building materials while maintaining strength over long spans, much stronger than any other natural materials.

How to Build with Sing Core Block

It is easy to build your own Sing Hardwood to use in your own designs. No more need to stock expensive hardwood inventories, unless you want to. In many cases it is much easier and ecologically advantageous to create your own Sing Hardwood using our patented Sing Core Block.

Here is an example of how to build a 2 foot by 4 foot panel using our Sing Core Block. First you lay your bottom skin face-down on your surface. Then you cover with a layer of urethane glue. Put your exterior wood staves (edges) into place, as shown in the photo to the right.

Sing Core Block is utilizes our, “drop-in,” system. Basically, all you need is to slice the Sing core lock your desired thickness as determined by your specifications. Install your sliced Sing Core Block by placing it inside your wood perimeter to fill the vacant space with Sing Core Block material.

Continue to fill the empty space with additional sections of Sing Core Block material until the space is nearly filled.

Sing-Core-Block-Drop-In-5

Here’s an exampled of Sing Core Block-filled vacancy

Next apply a layer of urethane glue to the top of all the surface material(s) including the exposed Sing Core Block and the top-side of the wood staves as shown in the photo to the right.

The honeycomb torsion box provides the strength, while the urethane glue adds to the structural integrity of the end product, keeping it from delaminating under extreme conditions or over long periods of time.

Once you have a nice coat of urethane glue on the entire top surface, you are now ready to apply the top skin.

This is a photo of the applied top skins in place.

Sing Press – No Equipment Necessary

Once you have all your glue and components into place, the panel(s) need to be cold-pressed for proper adhesion and dry-time. Dry times vary according to the type of glue that you use. We suggest using a slow-drying glue for a higher quality end-product.

Hydraulic Press

If your facility already has a commercial hydraulic press, then by all means use that. Many of our craftsmen who are Sing Hardwood manufacturers avoid any equipment cost by utilizing the Sing Press model, that is constructed out of perfectly straight Sing Panels on the top and bottom and a few clamps. There is no structural advantage of using a commercial press, as the results are the same.

You can see that very little energy is expended in the manufacturing of your Sing Hardwood, and there is little or no waste.

On-Hand = On-Demand

In the demonstrations (above) it is easy to imagine that you as the craftsman have complete control of the creation process. You can make your own Sing Hardwood on-demand at your location, avoiding any shipping expense or time… and if you need a piece of material that you suddenly find yourself out-of-stock… In an emergency, you could make your own (insert any hardwood or lumber product you want) if you have some Sing Core Block on-hand.

Wholesale Resource

Sing Core orders certain components by the rail car. We can pass on some of our savings to the craftsmen who use our Sing Core Block technology. You may find it beneficial to obtain wood staves, hardwood skins, glue (or other materials) from us to take advantage of our bulk buying power.

Note: For structural purposes, you as the manufacturer are liable for testing, licensure and code approval. Sing Core is not liable for any unauthorized use of any product created off-site using our patented Sing Core Block material. In the event that you intent to use your Sing Core Block material purposes, we may assist you in the process of getting the required testing completed.

Sing Timber

What is Sing Timber?

Sing Timber is a large mass of wood that can be milled to any specification. Its versatility is exemplified by wood shops who saw the large timber masses in more specific smaller planks as needed. Sing Timber can come in 12 inches wide by 12 inches tall and 96 inches in length, or you can get it already cut-to-order as Sing Hardwood.

Sing Timber can be broken down into any thickness and width, to create your own wood plank. You do not have to inventory all size of plank just by sawing Sing Timber to the desired thickness. You can slice the Sing Timber to any desired width, all you have to do is to seal the deal by gluing an exterior skin on the fresh sawed side to finish your new plank.

How Can I Use Sing Timber?

Sing Timber is manufactured with a heart of Sing Core, coverd with exterior skins on at least two sides form a large box like timber mass. It can be sawed horizontally, sanded and glued to form a smaller wood plank. It will create any dimensional wood and it cabn be covered any hardwood species, metal, plastic or even cement to create a new generation of ulitmate lightweight, high strength products.

Sing Timber is Better than Hardwood

Sing Timber’s Sing Core makes this the only hardwood material that is better than hardwood, for a integrous building material that is just a beautiful as solid natural hardwood with far superior structural integrity.

Sing Timber’s high-strength is due to Sing Core that is less expensive than solid hardwood. When Sing Timber is produced, the energy savings are impressive, as the actual production process uses less energy, man hours and equipment usage and produces little or no waste. Sing Timber is also sonstructed of low cost, renewable natural wood fiber and recycled EPS foam. Patented Sing Core is many times stronger than most of the core materials used in modern aircraft with much less weight and a fraction of the cost of core used in the aircraft industry. The cost can be less than 10% of the inefficient core used in aircraft design.

Compare other type of honeycomb or core materials , sing core is the only core physically and cost effective to build Sing timer which will turn to hundreds of different products for many industries.

How does Sing Timber work?

Simply stated, Sing Timber can be used as any regular lumber, cut to fit your appropriate application, as in shelving, Or you could add a solid wood edge to enforce the strength and add fastening anchor point for mechanical fastening.

When working with Sing Timber with a router, be certain to attach wood strips to the area to be routed, as the exterior wood surface along the face is minimal.

Sing Timber is versatile

Our most popular format in Sing Timber is the 4×12 in 8- and or 10- foot lengths. It can be used as a stand-alone post and/or beam as is, or (here’s the exciting part) can be turned into so many different products for multiple applications. For example…

Sing 4×12 lumber can be easily sliced into alternate widths and thicknesses to suit your needs. No need to make multiple trips to the store to pick up the lumber you need, simply slice Sing Timber 4x12s into the size that you want on-site; Perfect for the millworker or ambitious do-it-yourselfer.

By sawing the sandwich panel cross the Sing core to form two pc of sing sandwich without skin on one side than add new skin or add new solid wood to build a two sandwich panel or two Sing panels at different thickness. Sing Timber is easily broken down into any dimension wood plank or hardwood. Sing Timber can be easily sliced to substitute for standard 2×4 lumber.

How Do You Add Hardwood Stave?

It is easy to add a sardwood stave to any cut or sawed section of Sing Timber.

Firstly, all you have to do is to sand the surface of your freshly-cut exposed Sing Core section of your plank. Apply urethane glue or white glue to the smooth surface, then press. It’s that simple to turn a selection of Sing Timber into your own Sing Beam that is just as visually impressive as solid wood, but lighter weight and stronger than steel pound for pound.

Sing Timber is Strong and Straight

It is very hard to find straight hardwood without bowing, twisting or cracking. Solid hardwood is heavy, and hard to work with.

Sing Timber is an eco-friendly solid wood composite material with a patented Sing Core interior that results in lumber that is straight and flat, unlike any other building material on the planet.

Sing Timber is also available pre-cut as Sing Hardwood.
