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.
The Effisus Vapour FR Membrane is a high quality and multifunctional weatherproofing vapour barrier made of a special fiberglass technology with an aluminum foil, developed to achieve a fire reaction Class A1 in accordance with EN13501-1.
Works as a vapour control layer (VCL) protecting the building from condensation risk and improving the airtightness and consequently the energy efficiency.
Effisus Vapour FR Membrane can be used in facade rainscreen cladding, curtain walls and many other applications to protect the insulation and building interior from water, heat radiation and moisture transfer. It also works as a fire retardant layer in constructions.
