Application

Suitable for standard 600 mm joist centres. 

Description

Loft access hatches that have been designed and engineered under BS EN ISO 9001.


The 30-minute fire-rated (FR) push-up hatch is compromised of a hatch face that is a 6 mm masterboard with spray-applied vinyl finish and insulation infill. The hatch has pressed metal support brackets and the frame is fitted with intumescent strips.


Features and benefits:

  • All models meet or exceed the NHBC minimum opening size (NHBC Standards 7.2-D14).
  • Each loft access hatch is a complete unit comprising frame and door, with integral closed- cell 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.
  • The hatches provide continuity of thermal insulation at ceiling level.
  • 30-minute fire resistance with Class 0 surface spread of flame.
  • U-value of 0.35 W/m²K.
  • All Glidevale loft access hatches use insulation which has a Global Warming Potential (GWP) of less than 5 and an Ozone Depletion Potential (ODP) of zero.
  • The AH7 is matt white, which blends unobtrusively with a classic brilliant white ceiling.
