These amazing sliding accordion bi-fold doors are the incredible work of Brandner Design. They represent the ultimate use for Sing Core door cores; highest precision, highest strength, lightest weight, least warpage, most versatile.
Utilized for various applications, Sing Core’s patented panels have established themselves as a professional door core.
Sing Panels utilize patented Structural Core technology, which is sandwiched between two skins (wood, aluminum, or any other material that can bear weight).
This creates a torsion box, which allows our panel to be stronger, lighter, and truly flat with no warpage.
Proudly made in the USA Exported World-wide.
1/3 the Weight of Traditional Wood
30 ft. Sing wood pivot doors and Sing post and beams weighing 50% to 87% less than wood; exported and hoisted by crane atop one of the tallest buildings in Bangkok, Thailand. Proudly Eco-friendly, Made in the USA, exported worldwide.
Lightweight and High Strength
Sing Core’s 30 ft. large wood pivot doors are lightweight to be easily handled on the job site with less risk of injury, and less expensive to ship, even in a container overseas. University of Washington independently tested Sing Core panels at over 660 PSI.
50 year warp-free guarantee
Traditional doors warp; our panels don’t. We stand behind our lightweight, high-strength panels with the only 50 year-warp-free guarantee for our professional grade panels.
Insulated and sound deadening
Our patented Sing Core panels prevent separation of the foam and the skin, which provides insulation value and sound deadening qualities. R-values that range between 3.5 and 6.5 depending on the type of foam used. For sound, customize your door to reach the highest STC rating.
Recreate any material
Any substrate (skin) that is capable of carrying a load can be used as a skin with our patented Structural Core. We challenge you to find a lighter, stronger panel than our Cold Rolled Steel Composite Panels.
We use non-toxic glue for bonding skins to our Core. The structural material of Sing Core is made of 100% renewable material with vertical grain wood fibers.
