Jump to:

Application

Mainly used in pitched roofs and ventilated facades.

Description

A natural and ecological vapour-permeable, windproof and water-repellent thermal insulation board based on wood fibre made according to a dry process. The boards can be exposed to weather for up to three months and are waterproof according to BS EN 14964. In the case of open facade cladding, the installation of a UV-resistant membrane, such as Pavatex FBA, is required.

Features and benefits:

Can be used as a temporary roofing for up to three months.

Vapour permeable, but windproof and water-repellent.

CE marked.

Applications:

Mainly used in pitched roofs and ventilated facades.
