Glidevale improves loft hatch range

Some of the benefits of the revised range include:

• Integral seals to 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 of the Approved
• Documents, as demonstrated by test.
• Continuity of thermal insulation at ceiling level, substantially reducing heat loss by conduction through the hatch.
• Options with enhanced insulation meet the minimum U-value requirement of the Approved Documents.
• One hour and half-hour fire resistance options with Class 0 flame spread.
• Optional key-operated security bolts for tenanted properties or public areas.
