This high-performance door is crafted from durable stainless steel and filled with a combination of PUR polyurethane foam and wood for excellent insulation and structural integrity. The slab is 2.2 inches thick and features a dual sealing system—one in the frame’s dap and the other on the door’s supporting surface—to effectively reduce vibration and prevent heat loss. Resistant to atmospheric changes, the door maintains its shape and performance in all weather conditions.
The frame is equipped with anti-burglary reinforcements at hinge and locking points for enhanced security. The set includes the prehung door with two gaskets, a ROTO multi-point locking system with an independent upper lock and three anti-theft bolts, two sets of key inserts, a standard handle (T-bar long handle optional), viewfinder (for solid doors), three adjustable anti-burglary hinges, an aluminum threshold with a gasket, and three additional anti-theft bolts.
Thermal insulation reaches R-Value 4.8 for solid versions and 3.8 for glazed ones, with acoustic insulation rated at 31 dB for non-glazed doors. Glazed options feature triple-pane glass. Preassembled for convenience, this door is fully ready for installation right out of the box.
