Facadeshield FR Class B is a vapour-permeable monolithic membrane designed for use as the breather membrane in external wall constructions. It allows water vapour to pass through while providing resistance to external moisture in accordance with relevant industry tests. The membrane achieves a B-rated fire classification to EN 13501-1 and is supplied in roll format for ease of handling and installation. Facadeshield FR Class B should be used as part of a designed construction system and installed in line with project specifications and good practice guidelines.
To complete the system, use Proctor Class B Tape for sealing membrane overlaps, penetrations and interfaces. Designed to complement Facadeshield FR Class B, the tape provides a strong, durable bond that helps improve weather tightness, airtightness and long-term performance of the façade system.
Key to Facadeshield FR’s development has been ensuring the right balance of fire performance, water hold out and ultraviolet (UV) resistance – all in addition to vapour permeability that meets the definition given in BS 5250:2021.
Classified in accordance with BS EN 13501-1, Facadeshield FR achieves a reaction to fire of Euroclass B-s1,d0 and supports projects in meeting the fire safety requirements of national building regulations.
Assessed against the test methods in BS EN 13859-2, the membrane achieves the highest water resistance classification of W1. Facadeshield FR’s monolithic construction ensures its water hold out performance is unaffected even after months of UV exposure.
This is far longer than other similar membranes offer and is the biggest differentiator of Facadeshield FR compared to similar solutions in the marketplace. The membrane has been tested to 5000 hours of UV exposure.
Proctor Group supplies recommended tapes to support the installation of Facadeshield FR, and is on hand to provide expert technical support and toolbox talks. The membrane can be installed with a range of sheathing board substrates, including the company’s own Proctor A1 Cement Board.
