Door Core Comparisons

Many different varieties of cores are available and have been used by designers and door manufacturers to combat the problems associated with size, weight and structural integrity.

 


Why Architects and Builders Choose SingCore Panels

Feature SingCore Panels Typical Door
Construction Patented torsion-box composite core with rigid structural frame and insulation. Solid wood or steel-core door with wood facing.
Weight Up to 80% lighter than solid-core or steel-reinforced doors, making installation and handling easier. Heavy, often requiring extra-duty hardware, additional installers, or reinforced framing.
Warp Resistance Guaranteed never to warp, bend, or twist for 50 years. Solid and steel-core doors can move with humidity, temperature, and time — most carry only 1–2-year warranties.
Size Capability Can be built in any size — even 30 feet or larger — and still remain lightweight and true flat. Most large sizes require steel reinforcement or modular sections due to weight and deflection limits.
Thermal & Acoustic Insulation High-density foam cores for energy efficiency and sound control. Little or no insulation unless upgraded; dense cores can conduct heat and sound.
Design Flexibility Accepts any surface material — wood veneer, HPL, metal, FRP, concrete, stone, or your own custom finish. Typically limited to wood veneer or select finishes that can attach to heavy steel cores.
Hardware Compatibility Works with most hardware types due to lighter weight; reduced hardware cost and wear. Requires heavy-duty pivot hardware and thicker jamb structures to support door mass.
Shipping & Installation Lower freight cost, easier to handle, and safer to install due to lighter construction. High freight cost and complex handling; prone to shipping damage due to mass and balance.
Maintenance Less maintenance; structural integrity doesn’t degrade over time. Requires periodic refinishing and adjustment as materials expand and contract.
Sustainability Uses less raw material and long service life reduces replacement waste. Heavy materials and short life span increase environmental impact.
Warranty 50-Year Structural and Warp-Free Guarantee. Typically 1–2 years limited coverage.

  • If you want the look of a custom pivot door with the reliability of engineered aerospace technology, SingCore is the only door core designed to stay straight, strong, and lightweight for decades.
  • If you prefer a traditional handcrafted aesthetic and don’t mind heavier weight or higher maintenance, a solid wood or steel-core pivot door may meet your needs.

Insulation: Sing Core has built-in insulation value with an R3 to R6.5 rating per inch, depending on client’s needs/specifications.

Sound deadening: Sing Core’s filler material has natural sound-deadening properties. Other sound-deadening options are available at customer request.

Light weight: When compared to other materials Sing Core weighs much less, as much as 50% less, or more, as little as 4 lbs. per sq. ft. yet eco-friendly. This advanced technology used in the aviation industry is now available for use in your home.

Strength: Sing Core based on 2″ x 2″ grids and 3/4″ thick = 660 PSI. For instance, aluminum 3/8″ grids = 30+ PSI (smaller grids should be more strength). Sing Core’s superior strength comes from its advanced torsion box design.

Solid: Sing Core is solid like a rock. While the vertical wood grain torsion box core may be compared to other hollow honeycomb cores, the Sing Core voids are not hollow as they are bonded wall-to-wall and filled with recycled foam for a strong, solid substrate.

Eco-friendly: Sing Core is manufactured using natural wood fibers, no formaldehyde, or toxic chemicals, is created using less energy than any other core material with little or no waste.

Renewable: The structure of Sing Core is 100% renewable (nature-grown) clean fiber and/or recycled material.

Oversize: Sing Core excels in area of large oversize products due to its unique properties and can be up to 50 foot length.

Dimensionally stable: Sing Core is the most dimensionally stable building material allowing us to create large, oversize products (i.e., doors, up to 50 ft.) that are true flat exceeding AWI standards and can be guaranteed to be true flat. Large oversize panels can be truly dimensionally stable without any movement due to temperature and moisture change.

Affordable: Even though Sing Core technology is used in high-end applications, we make it affordable for broad use in a large number of applications. Sing Core performance is comparable to any high-end core but could be as little cost as low-end wood product core.

Waterproof upgrade: Sing Core is available in waterproof upgrade, to accommodate your specific water resistant requirements.

Fire retardant upgrade: When used in fire retardant applications, the Sing Core fire retardant door is the lightweight, super-strong, eco-friendly alternative.

Bullet-proof upgrade: In high-security end products, most cores used in bullet-proof applications are heavy in weight, causing strain on the infrastructure, unlike Sing Core.

Thickness available: Sing Core is readily available in many thicknesses, up to 6 inches in standard thickness, with custom thicknesses available.

Skin options: Available in many different exteriors including (but not limited to) aluminum, cement board, cold roll steel, concrete, ceramic tile, fiber glass, galvanize metal, glass, MDF, metal, plastic, plywood, solid wood, stainless steel, etc…

Easy to machine: Sing Core is easy to work with in the shop or on-site for sawing, sanding, adding solid wood implants, gluing, cutting and fastening.

Fast turnaround: In you’re in a rush, only Sing Core can be custom made within 24 hours and is proudly manufactured for you in the USA.

Pre-built Torsion Box for High-end Craftsmen

Imagine being able to build a torsion box work table – or anything, for that matter – without the time, energy and cost of building the torsion box yourself?

Traditional-Torsion-Box-Diagram

Sing core torsion box plywood lowes home improvement warehouse

Q: How easy is it to work with?
A: Just use your normal wood working tools and treat it just like you wood any other piece of plywood.

For years, inventor Peter Sing has been providing the military, high-end millworks and architects across the USA (see clients list) with massive torsion box structural panels that are lightweight and stronger than steel pound for pound.

lightweight panel honeycomb high strength guaranteed true flat table topsThe most experienced woodworkers agree that torsion box is the answer to hand-crafting a large wood, straight, structurally-sound table while having some control over the overall weight and responsible use of natural materials.

Sing’s invention revolutionizes the torsion box industry by tweaking the entire torsion box concept combining wood craftsmanship and space-age technology in his factory located in McCleary, Washington, cranking out solid torsion box panels that are proudly made in the USA for his upscale clientele.

Discerning wood workers who are called upon by designers and owners of multi-million-dollar homes face challenges especially when it comes to oversized big doors. While there is no doubt experienced wood workers can make the most beautiful wood doors for their discerning clients, invariably the doors fail if they are large in size due to the inherit nature of the wood itself.

Wood will move and adapt to temperature and moisture causing it to move, compromising the functionality and seal of the most elegant hand-crafted wood door. Diligent woodworkers have sought out sing’s solution to the oversized wood door.

The same scientific solution of reinforced torsion box applies to tables and other structures that can be built without traditional wood framing for furniture or stick-built homes.

Close up side view of exposed torsion box honeycomb foam core sandwich panel

Why Torsion Box?

Because other methods of building a table top are basically inefficient. For instance, a table top built of a solid material will shift and move over time compromising its degree of flatness. Also solid materials that are less likely to move are extremely expensive, heavy and would only be considered for a permanent fixture.

The torsion box table top design gives as flat a surface area as possible while reducing the weight of the table top due to the hollow areas in the center of the boxes. Using a torsion box design, a craftsman can build the most flat surface using 1/10th the solid material.

How do I build a torsion box table top?

DIY tosion box do it yourself how to build torsion boxMaterials needed: Wood for exterior frame, plywood for interior framing, saw, carpenter’s wood glue, cold press (with weight or clamps), meticulous measuring ability, focus, diligence and good minor motor skills.

Basically, you will need to establish the perimeter of your table top with an exterior frame according to the dimensions of your table. This exterior frame is generally made of wood.

The frame is built atop an underlying exterior surface material, most commonly, plywood (many varieties abound).

The most common torsion box material is plywood.

Building wood-framed boxes within the exterior frame wall-to-wall comprises the torsion box grid.

Once your torsion box structure is complete you can adhere top and bottom exterior plywood (referred to as stress skins) to complete your torsion box design.

Is it the perfect torsion box?

Probably not. The problem with traditional torsion box is that there is little or no shear strength, so if the structure is strained with enough horizontal torque the boxes could be compromised causing it to collapse. Plus, being made of wood still invites the base materials to move and give when adjusting to temperature or moisture in the environment.

How to build a better torsion box?

torsion box plywood cutaway sing core lowes home improvement warehouseInspired by traditional torsion box and using his experience gained in the aerospace industry, inventor Peter Sing created a better torsion box.

Materials needed: Wood frame, plywood strips (with grain oriented vertically as opposed to horizontally as used in traditional torsion box), saw, cold press, high-end waterproof formaldehyde-free glue, recycled dense foam that can be precisely cut into boxes.

Here’s how you build a better torsion box:

torsion box animationStart with your wood frame atop a stress skin, just like you would in the traditional torsion box example. This time run your plywood strips three inches apart, side by side, along the length of your exterior frame. (At this point it looks like you might be having mice race for the cheese at the other end, but keep your money in your pocket; there are no mice here.)

Now, place your 3 inch foam cubes between the vertical grain rails. Insert a 3 inch bumper (or stile) to close off the recycled foam completing your first row of interior boxes. Then place another 3 inch foam cube, followed by another bumper. Repeat until the entire interior area is filled wall to wall.

Adhere top and bottom exterior skins and you’re done.

Congratulations; you’ve just built the best torsion box structure ever!

How could you make it even better?

You’ve got to admit, as effective as it is, the tedious process is not only time consuming but expensive. But what if…

super honeycomb 2x4x1 2 ft x 4 ft x 1.5 in Sing Sandwich torsion box panel

2 ft x 4 ft x 1.5 in – no solid edge LT plywood

What if you didn’t have to build the torsion box structure at all?

What if you could buy Sing’s torsion boxes already pre-built for you?

That’s right. Mr. Sing’s factory is cranking out his patented torsion boxes by the truckload, and he’s offering special pre-built torsion box implants that measure 48 in. x 24 in. x 1.5 in. complete with stress skins for you to cut to size, drop into any frame for the perfect torsion box strength and lightweight design.

Sing Torsion Box is fast, easy, affordable, solid, lightweight, stronger than steel pound for pound and environmentally responsible.

How to I use Sing’s pre-built torsion box?

Make-your-own-Sing-Panel-Cold-press-methodIt’s easy to build your own products on demand, as you need it in any size you want.

This is the most popular in-house Sing technology used by craftsmen and millworks.

You might have never known how easy it is to build using this cold-press drop-in method.

How Easy Is It?

This is how simple it is to for you to use our pre-built torsion box.

Balsa Wood Alternative

foam-panel-guaranteed-true-flat-lightweight-strongSing Core is the new space age composite material that is the affordable cousin to Balsa wood and has many features that Balsa wood does not have. Using the best combination of science and nature, patented Sing Core is a Balsa wood hybrid, using a natural vertical wood torsion box design.

While torsion box has been used for centuries as lightweight structure, but Sing Core fills the open spaces with recycled foam (available in a variety of densities and material to meet your specifications), then the exterior surfaces (or skins) are bonded, completing the solid structure.

Weigh the alternatives and you can make an educated decision as to whether Sing advanced composites (the best of both worlds) will better suit your needs at less than one-third the weight of Balsa wood at less than half the price.

Balsa wood does have high compression, yet compared to other composite cores, Sing Core tests out at 660 PSI, that is stronger than steel pound for pound (even bullet proof doors don’t test that high). And Sing Core is more ecologically responsible as we use only 8% natural wood fiber (compared to balsa wood’s 100%) yet due to its unique design is much stronger when compared to other materials.

balsa-wood-treeUnlike Balsa wood, Sing Panels are resistant to warp, twist and rot, and they are pre-insulated for insulation and sound-deadening.

And Sing Core is so much more affordable than balsawood, especially if you are considering incorporating it as a lightweight substrate material for a large project, like a door, a table top, conference table, etc… See more applications.

Sing Core’s built-in torsion box structure, where the grid voids are not left unfilled but are filled with EPS foam provides a solid surface for bonding exterior building materials to that will not delaminate over time. Upgrading to closed-cell foam, makes Sing Core a perfect match for marine applications, like decking materials.

Big Aluminum Door

Patented Sing Core’s unique attributes enables us to make the biggest doors that are lightweight, extremely strong and Eco-friendly. Sing Core produces the only affordable solution to building a big door that can be guaranteed true flat… and will stay flat for lifetimes. Sing Core doors are pre-insulated and are resistant to climate change, bend, warp, twist, rot and insect threat.

big-aluminum-doors-37-foot-tallBig Doors for Your Big Expectations

Sing Core can help solve the challenges facing architects and designers. Obviously size is where Sing Core shines, but we also help solve other issues that face designers. Some of the functionality solutions that we help to provide include:

Lightweight

The larger a door becomes the heavier it gets. This can be a huge problem because these heavy doors cause strain on the structure and hardware. Lightweight big sing aluminum doors help to mitigate the damages of traditionally too-heavy-to-be-practical doors.

High Strength

There are other lightweight panels solutions that use honeycomb technology, but they simply do not have the strength, that is why the aerospace community is looking at Sing Core. Other lightweight composite core material used in aircraft are may not be heavy, but only weigh-in at 10-to-100 PSI, while Sing Core has been tested at 660 PSI, and could be upgraded to meet nearly any specification(s).

Eco-friendly

Green-eco-friendly-sing-coreIn this topsy-turvy world, Made in the USA Eco-friendly Sing Core is the true green building material that supports our commitment to make the world a better place for all of its inhabitants, while being the most significant, revolutionary new building material invention to be introduced in this century.

Affordable

When compared to other materials, like other space-age composite panels, Sing Core is not only more environmentally friendly but costs much less that the others. Why not get all the added value and benefit of Sing Core at a fraction of the price?

True Flat

One of the problems of big doors, is that they tend to warp or twist over time, making a secure seal all but impossible compromising your project and calling for continued maintenance. Not so with your big Sing door, which can be customized to be true flat literally forever even under the most rigorous conditions.

Stay Flat

It’s one thing to install a big door, especially a large sliding door, and have it be flat when installed… but only a Sing Core big aluminum door will stay flat, virtually forever. This means huge savings in maintenance costs due to having the door’s flatness fail over time.

Pre-insulated

Sing Core’s big aluminum doors are all packed with insulation imbued with an R-value that saves energy, while offering sound dampening qualities. And these values can be custom-suited to meet your specifications for energy efficiency or sound proofing.

Traditional-Torsion-Box-DiagramElement-proof

Your Sing big aluminum door is resistant to climate change and can handle the most extreme weather conditions per your specifications. Due to Sing Core’s unique vertical grain torsion box design these big aluminum doors are will not bend, warp, twist, rot or suffer damage due to insect or vermin assault.

How big can a Sing Door be?

To date, less than 50 feet for a single door panel is no problem… and we would certainly welcome the challenge of providing a solution that exceeds the 50 foot barrier.

How to Build a True Flat Long Lasting Carriage Door

How to Design Order and Build your Carriage Door

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

Wood-based carriage doors are exposed to a variety of weather conditions, glaring sun, wind and rain and it is important to keep the surface primed and coated to make sure that it does not crack while exposed to weather.

Sing carriage doors prolong functionality of surface treatments due to being made with patented Sing Core’s torsion box structure that holds the wood surface to maintain a forever flat surface without twisting or cracking.

You may further weather-protect – even for withstanding the most severe weather conditions – by integrating other material into the surface of your Sing carriage door. Surface skins of aluminum, FRP or stainless steel will not crack like natural wood or plywood to prevent compromise of your Sing carriage door.

If you like the look of solid wood but seek high-performance and longevity, you can use Sing aluminum as your true flat carriage door’s substrate, you will be able to maintain straightness of your doors making them less likely to crack due to movement cause by expansion and contraction of the wood surface material.

See how Sing Panel’s torsion box structure prevents surface crack because of the patented Sing Core’s unique characteristics.

To keep your carriage door true flat is a challenge for solid wood or even plywood.

Sing Core and Sing Panel master true flat technology for very high-end doors requiring less that 1/16 inch deflection which is more costly.

Sing carriage doors far exceed the AWI industry standard or ¼ inch deflection to be considered flat.

How to Attach Wood Planks to Sing Panels

Add-stiles-and-rails-to-your-sing-door-as-anchor-points-drawingSing Panels are so versatile, you can do just about anything with them.

As a matter of fact, prepare to adjust your thinking, because thanks to Sing Wood Planks you can,

Say Goodbye to Tongue and Groove

Tongue and groove joinery is designed to keep wood planks flat when attaching because wood moves. Natural wood (or most any wood product) tends to warp, bend or twist due to environmental changes.

Not necessary when using Sing Hardwood that is created true flat and will stay flat indefinitely.

What if you needed to attach wood or tongue and groove planks to the surface of your Sing Panel?

No problem.

Just make sure that you order your Sing Panel with the solid wood (or other material) implants to meet your requirements.

You can add stiles (vertical implants) or rails (horizontal implants) to have the anchor points that you need to match your expectations.

The only caveat, is that you must leave at least 12 inches of Sing Core material on either side of the implant in order not to compromise the sustained flatness of the lightweight, high-strength panel or door.
