Glidevale: Loft access hatches
Glidevale offers a competitive range of loft access hatches with insulation, fire protection and security options. Each Glidevale loft access hatch 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.
All models meet or exceed the NHBC minimum opening size (NHBC Standards 7.2-D14).
Each Glidevale loft access hatch is a complete unit comprising frame and door, with integral closedcell air/vapour seals and thermal insulation.
The 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 hatch door and exceed the
airtightness requirement of the Approved Documents, as demonstrated by test.
The hatches provide continuity of thermal insulation at ceiling level, substantially reducing heat loss by conduction through the hatch.
Options with enhanced insulation meet the minimum U-value requirement of the Approved Documents.
Optional key-operated security for tenanted properties or public areas.
1 hour and 1/2 hour fire resistance options with Class 0 surface flame spread available.
Suitable for standard 600mm joist centres.
