Description

Glidevale Protect loft access hatches have been designed and engineered under BS EN ISO 9001 to meet these latest demands. The AH7 1/2 hour fire-rated (FR) push-up hatch compromises a hatch face that is 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 Glidevale 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 0.35W/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.
