Fire retardant doors made with our patented Sing honeycomb/torsion box cores. Natural wood lock blocks are positioned at locations as necessary for locking mechanism placement or as anchor points. The core material is wood framed by 1 ¾ “ natural wood for finishing strength and attaching hardware. The torsion box is completed by adhering noncombustible 3mm Magnesium Board (standard) which results in 0 Flame Spread and 0 Flame Development.
