Designed specifically for concrete walls to reduce the risk of condensation, Kingspan AIR-CELL Permiwall® is an all-in-one insulation and vapour permeable membrane, offering advanced thermal and fire performance in a clean, fibre-free, thin medium as an alternative to conventional bulk fibre insulation.

Manufactured with a patented closed-cell structure sandwiched by highly reflective foil facings and pierced with tiny, evenly-spaced perforations, Kingspan AIR-CELL Permiwall® allows water vapour permeance while helping to achieve aSection J compliance. This system also keeps wall cavities clean and accessible for services such electrical wiring and plumbing.
