The Effisus Breather FR System is fire rated as Class A2-s1,d0 based on EN 13501-1 and Class A (or Class 1) according to ASTM E84, having obtained the final fire classification with Effisus accessories (tapes and adhesives) tested as a system.
It should be installed on top of the external insulation (cold side) protecting the entire façade composition. However, and depending on the cladding brackets complexity (size/shape) it is acceptable that breather membrane systems be fixed on the top of the sheating board. The weatherproofing design of the breather membrane systems should be done in detail and in project-by-project basis.
