AT25 Air Tight Drop Down Hatch is the first product of its kind to achieve airtightness under both positive and negative air pressure. By combining the best draught proofing and insulation, no other loft hatch offers as much potential to reduce heat loss and save on heating as this product does. This slender, hinged loft hatch has very clean lines, is easy to fit, easy to use and looks incredibly neat.
Fitting is simple, just screw fix through the pre-drilled holes in the frame into the surrounding joists. The spring loaded twist catch lock ensures a high compression seal between the door and the frame. The outer frame is also fitted with a seal to ensure air cannot easily escape from around the outer edge of the hatch. No additional sealant is required. Comes with fixing screws and plastic o-ring seals which maintain the air seal between the hatch and the fixings.
