BBA Agrément Certificate
BBA Certified - A1 class fire rated breathable membrane
BBA Certificate 21/5951
Effisus Breather FR waterproofing vapour permeable membrane uses an innovative technology, with a fibreglass basis to obtain fire resistance: Class A1 as membrane (tested stanalone) and Class A2-s1,d0 as membrane system (tested including all the ancillary fixing/sealing acessories) based on BS EN 13501-1.
Designed for global protection of facades against moisture, driving rain and wind, avoiding corrosion, insulation deterioration and mould growth on facade elements. It has an exceptional UV resistance and is suitable for facades with open or closed joints.
The existence of a large range of accessories allows its installation on the most demanding of projects. The final fire classification was obtained for Effisus Breather FR with Effisus accessories (tapes and adhesives), tested as a system.
The product should be installed on top of the external insulation (cold side) protecting the entire facade composition. However, depending on the cladding brackets’ complexity (size/ shape), it is acceptable for breather membrane systems to be fixed on the top of the sheathing board. The weatherproofing design of the breather membrane systems should be done in detail and on a project-by-project basis.
