The best performing airtight loft hatch available

❑  The AT35 metal loft hatch is the first air tight loft hatch of its kind. Insulated to meet Part L of the building regulations the AT35 is airtight in both positive and negative air pressures at 50Pa. This hatch is designed specifically to meet the stringent demands new properties are subjected to ensure they are as airtight and well insulated as possible. The air permeability test is based on BS EN 1026:2000 and BS EN 12207:2000 for a ceiling use only.

Easy to fit

❑  Fitting is a doddle, 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.

Appearance

❑  This steel loft trap protrudes just 2mm from the ceiling when fitted. You'll also notice its lovely clean lines and smooth finish (Powder-coated in white) it's the neatest loft hatch on the market. Let's face it does anybody really want a great unsightly lump of plastic protruding from their ceiling?
