Standard Sing Core 3 0 7 0 doors are manufactured with patented Sing Core material as the base interior substrate of the door. The Sing Core substrate material is created using a vertical grain natural wood torsion box design while the traditionally empty voids are filled wall to wall with recycled foam. The standard foam material is recycled rigid EPS foam. A 10-inch natural wood lock block is positioned centered at 37 inches for door knob and locking mechanism placement on both sides of the door. The core material is wood framed by 2-inch natural wood for finishing strength and attaching hardware. The torsion box is completed by adhering an exterior surface material (skin) in your choice of paint grade (Birch ply), wood veneer(s), or natural wood stave. Bonding agent used in adhesion of the entire composite material is formaldehyde-free.
