A2 Fire Rated AVCL System
Fire Rated Weatherproofing Vapour Barrier Membrane and required accessories.
The Effisus Vapour FR System is fire rated as Class A2-s1,d0 according to EN13501-1, having obtained the final fire classification with Effisus accessories (tapes and adhesives) tested as a system.
AVCL should be located on the internal face (warm side) of the back wall and fixed on the top of the vertical Galvanized Steel SFS Studs. The weatherproofing design of the AVCL system should be done in detail and project by project basis.
This solution is available at Effisus NBS Source profile.
