The T20, T18, T16, and T14 Series flush doors feature mineral board cores that provide a 250° (121° C) temperature rise rating, or 450° (232° C) at 30 minutes of test exposure, depending on hardware application. This makes the T Series ideal for stairwells in multi-level buildings, when occupants must evacuate in case of emergency.
The T Series doors are 1-3/4” (45mm) thick and offer a wide range of specifiable options, covering sizes, glass light designs, optional edge constructions and mechanical, pneumatic and electrical hardware preparations. Epoxy-filled mechanical interlock edges provide structural support and stability across full height of door edges.
