Wood Fibre Insulated Sarking Board

Pavatex Isoroof boards can be exposed to the weather for three months, and are “waterproof” according to the European standard EN 14964 for sarking boards. Isoroof boards are also insulating, and can therefore be included in the calculation of heat transfer. When used as sarking boards, please observe the country-specific application codes according to the regulations and standards in the technical documentation. The Isoroof board can be used as a vapour permeable, water repellent layer in external walls in timber constructions with clad walls. An additional facade membrane is required for open facade cladding, e.g. Pavatex FBA.
