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.
