Description :

Effisus ProFlex FR is a multi-layered weatherproofing membrane composed by a robust double side fire retardant polymer and fire retardant ultra-elastic reinforced core. This high-tech composite membrane was developed by an innovative bulk-forming process to efficiently control water, air, water vapour and moisture while accommodating differential movements along with fire performance. Effisus ProFlex FR is watertight and airtight membrane that combines an exceptional 200% elongation capacity with a fire performance of Class B-s3,d0 according to BS EN 13501-1. It was developed for sealing façade interfaces and construction joints on typical curtain walls, on rainscreen/brick ventilated facades, precast, masonry and many other applications.
