New company ATK has brought out a range of kits that are designed to improve airtightness where pipes pass through a building’s fabric. Called Airtightkit, the product is a sleeve that fits around the pipe where it interfaces with the cladding and provides an airtight seal. It consists of a flanged ABS sleeve that fits over the pipe and is screwed to the wall. A rubber gasket fitted between the flange and the wall provides the seal along with glue that fixes the sleeve to the pipe.

The company said field testing showed the product helped improve airtightness ratings. The kits are available to fit 21mm, 42mm and 110mm diameter pipework and are supplied with the sleeve, gasket, screws and wallplugs.
