permicav insulation air-cell kingspan Kingspan AIR-CELL Permicav® is an all-in-one insulation and vapour-permeable membrane designed specifically for walls with cavities to reduce the risk of condensation.

Manufactured with a patented closed-cell structure sandwiched by highly reflective foil surfaces and pierced with tiny, evenly-spaced perforations, Kingspan AIR-CELL Permicav® allows water vapour permeance while helping to achieve a 6-star house energy rating.
