Oversized doors are a challenge to build. But with our Sing Core material it will remain straight, strong, and lightweight for many years and eliminate the challenge of oversized doors for the architects and millwrights.
Prior to the introduction of Sing Core to the oversized door builders, door manufacturers and millworks found it impossible to offer any warranty on 8 foot doors, 10 ft garage doors or even larger doors. Now, thanks to Sing Core, they can build and offer a warranty on doors to remain warp-free for 50 years, even if the oversized door spans 50 ft.
Sing Core is a unique type of material that is made form a combination of a patented honeycomb core and high quality wood. Thus creating a lightweight and extremely strong product. If your oversized door has professional Sing Core inside it can be guaranteed to be warp-free for 50 years, including full structural warranty. No other door can be guaranteed to be warp-free unless it has Sing Core inside.
The Big Challenge
The trouble with oversized doors today is that all over the USA and around the world if the doors are large doors meaning over 7 ft. tall and 3.5 ft wide, problems will arise causing the door to fail because overtime all big doors warp. Sing Core solves that problem quite nicely.
If your oversized door has professional Sing Core inside it can be guaranteed to be warp-free for 50 years, including full structural warranty. No other door can be guaranteed to be warp-free unless it has Sing Core inside.
Behind the Warp-free Oversized Doors
The secret of creating a warp-free oversized door has been discovered, and the answer is Sing Core. Besides being guaranteed warp-free for 50 years, your high quality doors with Sing Core inside offer other features. You can expect some amazing additional attributes due to the composite structure of Sing Core door blanks.
Sing Core is a solid internal door core designed for oversized doors that weighs a fraction of other solid wood door cores. Oversized doors with Sing Core inside can weigh 100 lbs. each in comparison to the 1,100 lbs. each of the original solid core large doors being architecturally replaced.
- High Strength
Sing Core has been independently tested and rated at 660 PSI. That’s stronger than steel pound-for-pound. No other lightweight door core material is stronger or more effective for oversized doors that can withstand over 600 lbs.
- Warp-free, and no Bend or Twist
Professional Sing Core will not warp, bend, twist or otherwise fail due to the vertical grain torsion box structure reinforced with rigid structural strength foam insulation and patent pending stiffeners. Sandwiched between two stress skins. Sing Core is the only door core material that can be guaranteed warp-free for 50 years.
Sing Core is packed with insulation for climate control and sound deadening characteristics ranging from R3.5 and up per inch due to the structural insulation used inside the torsion box structural grids. Foam can be upgraded from our standard EPS foam (R3.5) for even more insulation per your specifications by using Polyurethane foam (R6.5), Polyisocyanurate (R7.5), Phenolic (over R8) or other more advanced foams that may be available to meet your specifications.
