Description
The GL 280 F Drop Down One Hour Fire Rated Loft Access Door is designed to be
flush fit to the ceiling and to fit between 600mm centre trusses. The modern
design fits in with almost all house decor styles. Finished with a light
texture, the door can be easily cleaned with a solvent free, damp cloth, or
alternatively can be painted to match the surrounding decor.
Draught seals are located to all 4 sides of the door and seal to the frame
complete with latch preventing the problem of moist, warm air entering the roof
space.
The Fire Rated Loft Door (GL 280 F) comes with a lock and ‘T’ key as standard.
The loft hatch fire rated access door met the British Standard recommendation
for a leakage rate of <1m³ at a pressure differential of 2 Pa, and the Building
Regulations Part L2A ‘reasonable limit’ for the design air permeability of
buildings of 10m³/h.m² at 50Pa.
