How Sing Core Works With Architects
SingCore gives architects the flexibility to realize their creative designs without worrying about the details of construction. Our doors panels come in any look and any size – you just specify the dimensions, material, and “SingCore inside!” We can handle everything from specialty curved doors to extreme oversize doors assembled in sections and joined on site.
The process works something, like this:
- The Architect specifies, “SingCore” inside the products, let’s say, a large pivot door
- The General Contractor seeks out a qualified Millwork who obtains unfinished pivot door from Sing Core
- Sing Core manufactures the pivot door blank to architectural specs and ships to millwork
- Millwork finishes and installs hardware and provides finished pivot door to the job site
- Installers hang and or install the pivot door
The unique attributes of patented SingCore assists in bringing the creative concepts of architects to life in the real world. Ideally, architects who understand SingCore’s unique characteristics specify SingCore in their designs.
We are seeing even more architects working in tandem with our team to solve the challenges with traditional materials. Basically, when a problem associated with weight or strength rears its ugly head, SingCore is the Eco-friendly solution. In the event the architect was unaware of the size and/or weight issues associated with his or her design, it is not uncommon for the general contractor or millwork to seek SingCore to solve the problem.

We see trends in the problems associated with particular architectural designs where patented SingCore is clearly the solution. Though we ship all over the world, most of our products ship 3,000 miles away to New York (less expensively than other materials due to the decreased weight) where we solve issues for FAIA members’ concerns about large sliding doors and help door companies deliver warp-free large doors to increase integrity and viability. We also assist AIA chapters (like this one in Seattle) create outstanding Centers for Architecture and Design. (Follow links for more information on these projects.) See Clients List
Here are the most common problems solved
Any doors built with SingCore inside will weigh a fraction of other materials, yet can host any flat exterior material per architectural specification. For instance, a solid hot rolled steel door would be extremely heavy, which is a concern in terms of expensive hardware and potential additional stress and strain on the structure. The same hot rolled steel door with SingCore inside (approximately 4-6 lbs. per cubic foot) weighs a fraction of the weight without compromising strength, as SingCore is stronger than steel (660 PSI) pound for pound. See Steel Doors
Big doors are problematic due to their size which causes concerns of weight and potential to compromise due to warping. SingCore is used extensively in large doors to maintain their structural integrity, to be straight and stay straight over time, so as not to create problems with leaky door seals requiring regular maintenance. Only doors with patented SingCore inside can be structurally guaranteed to be true flat and warp-free for a full 50 years, even if the large door in question is made of natural wood(s). See Large Oversized Doors
Sing Core is made in the USA with the most sustainable processes and composite materials, such as natural wood fiber inside the core, formaldehyde-free glue and the manufacturing process uses manual labor and very little energy to produces with little or no waste. Plus, due to the lighter weight of Sing Core (about 10% the weight of solid wood products) we ship Sing products all over the United States and the world abroad, at a fraction of the cost while reducing the energy consumed and the associated carbon footprint in the transportation process. In addition, Sing products are reusable. and repurposable following installation or demolition.
The issue of heavy weight is the first thought that comes to mind as Sing’s core is so effective at reducing the weight of the otherwise overweight modern steel pivot doors, which results in a door that can be shipped less expensively, easier to handle in the shop and on the job site, and requires much less expensive “heavy duty” hardware to accommodate these modern steel exterior doors with Sing Core inside. Whatever the steel weighs (+ 10%) will be the weight of the door. The heaviest gauge you would need is 18G, and 20G is best and looks like a solid steel blank.
Stronger than Steel
Sing’s revolutionary technologies empower contemporary architects, door designers, the biggest and best companies to provide their clientele with modern stainless steel entry doors that are lightweight yet stronger than steel pound for pound. Sing Core was tested to far exceed 660 PSI.
How can 20 Gauged steel be so much stronger? Why? See unbreakable glass:
Glass stronger than steel? Even hitting unbreakable mirror with a hammer does not break.
When compared to other core materials Sing Core is extremely high precision maintaining the highest tolerances (+/- .006 in.) across the entire span of the panel. You can feel confident knowing this lightweight, high strength building material maintains a high level of accuracy throughout your project.
All Sing Panels are packed fully insulation, custom manufactured to architectural specifications in our Pacific Northwest factory, they can be made of any flat building material, in any shape, and any size (up to 50 ft.) are lightweight, high strength and Premium Sing Panels can be guaranteed to stay warp-free for 50 years. See Insulated Aluminum Panels
Large Production Runs
Sing’s factory is setup to do large production runs for all types of doors, including stile-and-rail-style doors, at a fraction of what it would cost a busy door factory to setup and retool for a large quantity order. The biggest door companies in the world rely on Sing’s factory to do the “heavy lifting” on their large non-standard-sized door orders, saving time and money.
Our true flat team can help you to engineer the panels you need to achieve the results you want to deliver to your clients without compromising the integrity of your design. Years of experience with our patented material and patent-pending warp-prevention technologies can be a valuable resource to you and your team.
50-Year Warp-free Guarantee
One of the most important characteristics of Sing Panels is their ability to remain straight and true without added support. Even long spans can be covered with very little deflection, even under significant loads. Due to Sing Core’s ability to cover long spans, this characteristic is key in our ability to make warp-free doors of any size, of any material, in any style that can be guaranteed not to warp, bend, twist or otherwise fail for 50 years. Large doors (over 8 ft tall) do not have a warranty because everyone know they will fail due to warp, that is, unless they are guaranteed not to warp due to their having specified, “Sing Core inside.”
Sing offers the only 50-year guarantee that your doors will not warp, bend, twist, or otherwise fail (including structure). If we couldn’t do it, you would not be reading this statement now.
How Do You Do It?
Peter Sing, the inventor of Sing Core, developed a hybrid building material of old and new technologies leading to this new approach to dealing with the issues concerned with weight and strength. Basically, the base structure is vertical grain (much stronger than horizontal grain) torsion box filled with recycled rigid foam insulation sandwiched between two stress skins using formaldehyde-free adhesives.
The result is nothing short of a breakthrough in building materials making creations more possible in the real world.

Design hint for weight, strength and flatness of Sing materials
We are able to accommodate the weight and strength you are looking for in your design. For instance, an average 2 inch thick door weighs from 1 to 2 lbs. per sq. ft. It is easy to attain adequate strength even if your designs are sleek and thin.
Other types of core requires enough thickness to achieve a certain strength, such as core materials made of paper, plastic or low grade aluminum honeycomb core. If it is large panel or large door plank then we need to know your desired tolerances for true flatness. We routinely build 20 ft. tall doors as straight as following a straight line, by using Premium SingCore inside large doors otherwise we be able to target within your individual requirements.
Sing Core exceeds current code requirements. For example, in the door industry, AWI’s guidelines dictate that a door should be less than ¼ inch flatness. Sing Core routinely builds doors that are over 10 ft or longer in length, yet exceeding those 7 ft doors code requirements. Doors made of Premium Sing Core provide 50 years of structure and warp-free warranty. (As a common practice in door industry, most manufacturers offer only a one year warranty.)
Products made with patented Sing Core can be easily repaired without compromising it’s original strength, due to the structure of Sing Core and the bonded stress skin which when compared to solid wood and other types of solid materials would pose a significant challenge.
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.
Sing Core’s mission is to provide superior eco-friendly product to architects share a common goal with Sing products; to build a better World creating a healthier, green planet, benefiting all creatures and life forms for extended sustainability for the future.
