Facadeshield FR Class B is a vapour-permeable membrane with a monolithic construction, designed for use as a breather membrane in external wall systems. It allows the passage of water vapour while providing reliable resistance to external moisture in accordance with relevant industry standards. The monolithic structure supports long-term durability, maintaining water holdout performance even after extended UV exposure. The membrane achieves a Class B reaction to fire in accordance with EN 13501-1 and is supplied in roll format for ease of handling and installation.

Facadeshield FR Class B should be incorporated within a designed construction system and installed in line with project specifications and good practice guidance.
