Loft Access Traps
LOFT ACCESS TRAPS
The energy conservation and air leakage requirements of Building Regulations (Approved Documents L and C) mean that a loft trap needs to be a high-performance product.
Site-constructed traps are no longer adequate. Glidevale Loft Access Traps have been designed and engineered under BS EN ISO 9001 to meet these latest demands.
Each Glidevale Loft Access Trap comprises a frame which is fixed into a trimmed opening and has a seal to the ceiling and a trap door which is thermally insulated and has a flexible closed cell seal between door and frame.
Integral seals significantly reduce water vapour migration into the loft space, reducing condensation risk.
The seals also virtually eliminate heat loss by air movement around the trap door and exceed the airtightness requirement of the Approved Documents, as demonstrated by test.
The traps provide continuity of thermal insulation at ceiling level, substantially reducing heat loss by conduction through the trap.
Some additional options available are;
- Enhanced insulation meet the minimum U-value requirement of the Approved Documents.
- Key-operated security bolts for tenanted properties or public areas.
- Half-hour fire resistance option with Class 0 flame spread on LA5 model.
- One hour fire resistance on LA6 model.
