Application

Suitable for standard 600 mm joist centres.

Description

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


A 1 hour fire-rated (FR) hinge-down hatch that is compromised of a door and frame that are formed from 1.0 mm and 1.2 mm Zintec electrogalvanized mild steel finished in polyester powder coating with insulation infill. Closed cell gaskets. Concealed key-operated lock. Optional high-security lock for communal areas is available.


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.
  • 1-hour fire resistance with Class 0 surface spread of flame.
  • Meets or exceeds the NHBC minimum opening size.
  • 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 0.
  • The AH6 is polyester powder coated in white, which blends unobtrusively with a classic brilliant white ceiling.
  • U-value of 0.35 W/m²K.
