Glidevale Protect AH4 Part L Push- Up Hatch - Loft Access Hatch

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.
