Application

Glidevale Protect loft access hatch. Suitable for standard 600mm joist centres.

Description

Glidevale Protect loft access hatches have been designed and engineered to BS EN ISO 9001. Each Glidevale Protect 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.
  • U-value of 0.35W/m²K.
  • 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.
