Glidevale Protect AH6 1 Hour Fire-Rated Hinge-Down Hatch
Application

Suitable for standard 600mm joist centres.

Description

Glidevale loft access hatches have been designed and engineered under BS EN ISO 9001 to meet these latest demands. The AH6 1 hour fire-rated (FR) hinge-down hatch compromise's 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. Option: High-security lock for communal areas.

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 and 1/2 hour fire resistance options with Class 0 surface flame spread available.
  • 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.
  • Meets the minimum U-value requirement of the Approved Documents.
