Effisus Vapour FR - Airtight Vapour Control Layer

BBA Certificate 21/5951 (Product Sheet 1).

High quality and multifunctional weatherproofing airtight vapour barrier manufactured from fibreglass technology with an aluminium foil, developed to achieve a fire reaction Class A1 as membrane and Class A2-s1,d0 as system according to BS EN 13501-1. The final fire classification of the system was obtained for Effisus Vapour FR membrane with Effisus ancillary items/accessories (fixing/ sealing tapes and adhesives).

The product should be located on the internal face (warm side) of the back wall and fixed on the top of vertical Galvanized Steel SFS Studs. The weatherproofing design of AVCL membrane systems should be done in detail and on a project-by-project basis.

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 EN 13501-1.

Works as a vapour control layer (VCL) protecting the building from condensation risk and improving the airtightness and consequently the energy efficiency.

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.

Features and benefits:

• Fire protection: Class A1 as membrane and Class A2-s1,d0 as system according to BS EN 13501-1 (system: Effisus Vapour FR membrane with Effisus fixing and sealing accessories).
• Fire protection: Class A2-s1, d0 according to BS EN 13501-1 (Effisus Vapour FR membrane tested with Effisus fixing and sealing accessories).
• Multifunction: 100% water, vapour and airtight.
• Resistant: High mechanical resistance with resistance to thermal variations.
• Complete system: Complete range of accessories for any project needed. Possibility of combining with an A1 Effisus Breather FR membrane to have a full envelope fire-rated system.
• Energy efficiency: The airtightness of the membrane improves the air quality in the building interior, thermal efficiency, durability of all the facade components and avoids condensation risk.
• In accordance with LEED v4.1, EMICODE, BREEAM International (Exemplary Level) and Indoor Air Comfort GOLD – Eurofins.
• Complies with the Directive 2011/65/UE and its subsequent amendments Directive 2015/863 related with hazardous substances.
