Glidevale Protect AH4 Part L Push- Up Hatch
Application

Loft access hatches.

Description

Glidevale loft access hatches have been designed and engineered to BS EN ISO 9001. Each Glidevale loft access hatch comprises a frame that is fixed into a trimmed opening and has a seal to the ceiling, and a hatch door that is thermally insulated and has a flexible closed cell seal between door and frame.


The AH4 push-up hatch door is injection-moulded polypropylene with insulation infill. Twin latches, and an anti-wind uplift mechanism at the opposite end of the door, prevent the hatch from becoming dislodged if there is severe wind gusting. Option: Two lockable security bolts.


Features and benefits:

  • 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.
  • Meets the minimum U-value requirement of the Approved Documents.
  • The hatches provide continuity of thermal insulation at ceiling level, substantially reducing heat loss
  • 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 zero.
  • Lightly textured scuff-resistant white finish, which blends unobtrusively with a classic brilliant white ceiling.
