ISOLAIR

Permeable sarking board

PAVATEX sarking boards can be exposed to the weather for three months, and are “waterproof” according to the European standard EN 14964 for sarking boards. ISOLAIR sarking boards are simultane- ously also insulation boards, and can therefore be included in the cal- culation of the heat transfer. When used as sarking boards, please observe the country-specific application codes according to the regu- lations and standards in the technical documentation. ISOLAIR sark- ing board can be used as a vapour permeable, water repellent layer in external walls in timber constructions with clad walls.
