Daniel Sing Core No Comments

Real Wood but 1/3 the Weight of Solid Wood

Sing Core is a patented and patent pending real wood material. With a real wood exterior, and an environmentally friendly wooden torsion box core, you get the look of real wood, with one third the weight and a strength greater than steel by weight. Further, our custom panels do not warp.

Our material can be worked with ordinary woodworking tools. And, is in almost every respect a superior light weight alternative to wooden planks, beams, and sheets.

What Kind of Wood is Lightweight?

When you think of light woods, your mind typically goes to Spruce, Balsa, Box Wood, or some other exotic tropical variety.

But, here at SingCore, we specialize in super lightweight wooden panels with almost any wood finish. Need a walnut panel that weighs less than spruce, then we can make one custom just for your project. Wood skins can supply include, but are not limited to:

  • lightweight-panelPine
  • Cedar
  • Cottonwood
  • Alder
  • Ash
  • Oak
  • Walnut
  • Beech
  • Maple
  • Birch
  • Teak
  • Mahogany
  • Fir
  • Cherry
  • Rosewood
  • Elm
  • Larch

 Is Balsa Wood the Lightest Wood in the World?

No! SingCore is the lightest wood in the world! Our lightweight and super strong core is both 1/3 the weight of typical wood or less, yet stronger than Oak. If you need something that exceeds every other material that you have worked with in the past, then you need SingCore.

Which Wood is the Strongest?

The strongest wood in the world is SingCore. Our wooden torsion core, with custom exterior faces with any wood veneer, wood stave, metal, plywood, plastic, or other finish, is stronger than steel by weight. Yet remains surprisingly light for its size.

Lightweight Wood Sheets

Sing Core makes the lightest and strongest wood sheets on the market. All our panels are made directly to order. All we need from you is the desired length, width, thickness, and desired skin finish.

Our wood sheets are guaranteed not to warp, and are covered by a 50-year structural warrantee. Although we are not the cheapest, we stand by our product the longest of any manufacturer in the market.

Lightweight Wood Board

Sing Beam and Sing Board can be custom made for you application. Easy to move. Perfect straight. Lighter than wood. But, stronger than steel.

What Kind of Wood is Light but Strong?

For a light board or panel that has the look of wood, with solid wood staves, but is much lighter than wood should ever be, then you have come to the right place. SingCore makes custom, to order, panels that exceeds the strength of any other wood on the market.

Lightest Wood for Shelves

Sing core panels make amazing shelves. With little to no VOC, they can be used in almost any sensitive situation.

The panels are so strong that they can easily support the weight of a morbidly obese man, yet they remain remarkably light to the touch.

Professional Sing Panels

The only 50 year warp-free guarantee and full structure warranty

Patented premium warp free singcore panel with embedded stiffenersAll Professional Sing Panels are guaranteed not to warp and maintain full structure strength for 50 years.

Custom size and thickness available at almost all sizes and thicknesses. We are experts in manufacturing true flat panels and non-warping panels for very large doors, walls, tables and more…

Professional Sing Panels commonly have a solid wood edge (1.25 inch is standard, any custom size is available). 

Professional patented SingCore creates the best non-warp, lightweight, high strength panel material for superior construction with embedded professional stiffeners. Standard Sing Panels continue to break all records for flatness but it will move if the skin is made of porous materials (non metal or plastic) without professional stiffeners.

If you are an architect, general contractor or home owner and expect a non-warp guarantee from the door manufacturers (especially the very large and expensive doors) you would be very hard-pressed to come to an adequate warranty arrangement with either a door manufacturer or millwork because large doors and doors made of exotic woods are prone to fail; that is, unless the door is made with Professional Sing Panel inside. This is how we help to make the best doors in the world that can be guaranteed for structure strength and not to warp for 50 years.

In the event one side is exposed to excessive moisture or temperature then it could cause warping if the panel is very thin. If you have high expectations for non warping (which most of the high end large doors have problems with) Professional Sing Panels are the only insulated panels that warp less than any known core material. All Sing customers are happy with what we deliver when using the Professional Sing Panel to build their non-warping doors; which is changing the previously known idea that all the large doors in North America warp due to the change of seasons. The secret inside the best non-warping doors is the Professional Sing Core which keeps the Professional Sing Panel flat from our factory to its destination and stay flat for 50 years with structural integrity guaranteed.

A Professional Sing Panel consists of a substrate of patented SingCore® torsion box reinforced insulated core with special patent pending Sing stiffeners sandwiched between two ¼ inch sheets of plywood, resulting in the most Eco-friendly lightweight and high-strength (660 PSI, stronger than steel pound-for-pound) non-warp material. The Professional Sing Panel is the basis of many applications spanning a multitude of industries and is available to the public via special order from Lowe’s Home Improvement Pro Desk.

Premium Sing Panel SealStandard Professional Sing Panel

Build your own non-warp door without the extended delivery time

The Professional Sing Panel takes the standard Sing Panel to a new level of high precision and increased performance. The Standard Professional Sing Panel comes in standard 4 ft. x 8 ft. x 1.5 in. size with 1.5 in. solid wood edges that can be cut, ripped or sawn into any shape, size or thickness in your wood working shop (no special tools required). If you remove solid wood to create your idea target size, all you need is router the core on the open side and glue back a piece of solid wood to build the size of panel in your shop without any extended wait time… On demand, in your warehouse when you need it.

Standard skin = 1/4 inch lightweight plywood Option = Marine-grade plywood Includes 1.5 in. solid wood edges.

Standard Professional Sing Panels are specially reinforced for increased performance by our team of experienced professionals with an acute sense of composite technologies to create a professional panel that will have the structural integrity to far exceed performance standards deemed “acceptable” by the trade industry.

The Professional Sing Panel is available only to trade professionals, includes embedded stiffeners and is cold-press-ready or available as paint grade or with natural wood stave surfaces. Click here to see skin options. For Hot-press-ready see Hot-Press-Ready Sing Panel.

ProfessionalNon-Warp Door Blanks

Non warping door blanks guaranteed no warp doors sing coreProfessionalSing Panels are also available in a variety of standard sizes for Guaranteed Non-warp Door Blanks. Using patented Professional Sing Door Blanks, any door can be made in any style of any material in any size that can be guaranteed to be true flat (well above AIA standards for flatness) and not to warp for 50 years including structure guarantee when used for intended purposes for which the door was designed.

Case Study

The largest door manufacturer in the East Coast has been struggling with the challenge of building large oversize doors.

The Problem: Not long after installation, the doors will warp.

The Solution: Using Sing Guaranteed Non-warp Door Blanks this door manufacturer can now make non-warping doors to meet any specifications.

Details: Originally, the East Coast door manufacturer purchased custom door blanks as needed to fill the need as it arises; then opted to order a stock of standard-sized Professional Sing Panels to keep in stock for building their own non-warping door cores on demand. Standard stocked sizes are 4 x 8, 4 x 10, 4 x 12, 5 x 8, 5 x 10 and 5 x 12. Manufacturer reports ease of cutting to size, routering and inserting wood stiles or rails to specs.

Premium Sing Panels 50 Year Non-warp Guarantee for exterior useCustom Professional Sing Panel

Available with all the options available in the classic Sing Panel, the Custom Professional edition has even more strength, integrity and ability to span distances with little or no support and little if any whatsoever.

Custom Professional Sing Panels  are available in any size, any thickness i.e., large oversize panels or planks, posts and beams, with any of the following custom options.

Tiny House built in 1 day – last forever!

Making your dreams come to life are quick, easy and painless with our new Sing Slot Panel designs that could be used in endless applications

Here’s a story from a fan who used indoor micro-sizing concept based on tiny house concepts to reduce winter hearting costs:

Sing Slot Panel Testimonial

I just wanted to offer a sincere debt of overwhelming gratitude. I have a modest but large home that generates an exorbitant amount of energy consumption, especially in the winter to heat. This became completely unmanageable when I got laid off from my regular employment.

Living alone, I thought, if I could just minimize my heating requirements, I could increase my chances of survivability while downsizing without having to sacrifice my home.

Sing Slot Panels fit the bill. In a few hours I was able to reduce the heatable inner dimensions of my home to several individual boxes. My kitchen and bathrooms are already well-contained and easily heated when in use. The Sing Slot Panels helped me to quickly build a small bedroom within my bedroom, small living room within my living room and small office within my office.

And when I have the family or guests over, I can easily disassemble and store my downsized rooms, so no one’s the wiser.

This has saved my life and my home, while I only heat the space that I need.

Thank you,

D Marturion, Blaine, Washington

Engineered Plywood

Patented Insulated Torsion Box Plywood
vs. Traditional Plywood

Engineered-plywood-cutaway-exposing-vertical-grain-torsion-box-and-foam-insulationSing Engineered Plywood is the new technological breakthrough in building materials that provides aerospace, US military, high-tech corporations and high-end home designers with an Eco-friendly plywood that is lighter in weight than traditional plywood yet stronger than steel.

In the world of composite panels, much headway has been made in combating the challenges associated with the heavy weight of plywood; leading to the development of lightweight composite panels with a variety of inner core materials, like paper, cardboard, aluminum honeycomb and a wide variety of foams.

Inventor Peter Sing has released this new advanced technology to the world, making it more affordable that other highly engineered materials previously used in the aerospace industry.

Sing Engineered Plywood is available in your choice of solid wood (or other specified edging material) or no solid wood edging.

Sing Engineered Plywood is made with our patented torsion box design technology at the core. A torsion box work bench has been the dream of fine wood crafters for centuries. It takes time and skill to create a truly flat, strong and lightweight work bench, but inventor Peter Sing has solved the challenge of torsion box production with his patented Sing Core which has been used to build an endless variety of products that we use in our daily life.


You can build an entire house with our patented torsion box structure, even our furniture is made of our torsion box Sing Core. Sing Core is the king of torsion box composite engineered plywood. Our engineered plywood is the strongest, most Eco-friendly plywood ever invented.

New Revolution in Composite Materials

The only affordable Eco-friendly, high strength, lightweight composite building material with endless applications

Sing Core is the strongest (see core comparison) low cost core ever invented and is extremely lightweight, with so many other features making Sing Panels the best substitute for solid materials, such as wood, metals, cements, plastics, etc…

How easy is it to use as substrate?

Simply remove the solid substance of those material and replace with Sing Core and, “Voilà!” You have hollowed out the center of the solid material – which is heavy and it is not necessary to enforce the strength due to the stress skin of the unique Sing panel structure – and if you double the thickness of the exterior surface material yields 4 times the strength.

True Dimensionally Stable…

Foam-Panel-Interior-Structural-Torsion-Box-Sing-Core-RevealedMakes your end result more beautiful and long-lasting than solid wood, engineered wood, metal, cements or plastic…

Sing Panels are made of patented Sing Core which is based on wood torsion box filled with foam forming a lightweight, super-strong base material. By adding hardwood veneer or stave you will create a Sing solid wood alternative which appearance and functionality is more high precision. The result is a building material that looks just like solid wood with little or no distortion (solid wood could move according to moisture and temperature change) yet stronger than steel pound for pound.

This revolutionary new high-strength interior structure provides the most dimensionally stable panel. The torsion box structure is made of renewable vertical grain veneer otherwise hollow pockets are packed wall-to-wall with sound deadening insulation recycled foam. The exterior surface materials (or “skins”) of Sing Panels are bonded to the Sing Core structure with zero formaldehyde structural glue to provide the highest quality to meet the demands of high end millworks.

Easy to Build Almost Anything…

architectural-hardwoods-kitchen-cart-chopping-blocks-true-flat… and everything by cutting, slicing and face-gluing to create different thicknesses and dimensions. Sing Panels could be used as core for endless applications in wood working, metal fabricating, concrete, masonry and so many other industries by itself. These composite panels can be cut to any size (cut and rip just like you would any plywood material without special tools or equipment) and used as substrate by adding final skin with common white glue (carpenter glue) and simple clamps to make all types of lightweight high strength wood, fiberglass and metal products.

You may slice and sand Sing Panels to your desired thickness and add a new surface skin on the fresh sanded sides of Sing Core with urethane glue (similiar to gurrila glue). Create a thicker panel by sandwiching two Sing Panels together (or just contact us to order specific thickness) for your job requirement.

Replace Traditional Building Materials

Sing Panels are replacing solid wood, particle board, plywood, MDF as the strongest lightweight Eco-friendly core materials ever invented. Patented Sing Panels are most commonly used as door and/or table and counter top substrate and a host of other applications.

These sandwich panels are commonly compared to honeycomb sandwich panels which are primarily hollow, in that the honeycomb voids are empty, and rarely, if ever, achieve strengths over 100 PSA, while Sing sandwich panels were independently tested to achieve over 660 PSI (and higher) for superior strength and structural integrity.

The unique attributes of these newly invented, patented sandwich boards cannot be challenged in terms of insulated Eco-friendly, lightweight, high strength sandwich panel.
