EFFISUS’ core business is focused on efficiency, sustainability and innovation: the three key aspects which have driven the company down the years. With the aim of adding value to the construction market, EFFISUS provides Building Envelope solutions (water, air, heat, light and noise) to maximize the performance and lifetime of buildings, and works to meet the different needs of customers, differentiating itself from the rest of the market by offering a complete service.

Aware of the huge gap in the market for sealing façade interfaces, which hasn’t changed for decades, and also the need to use non-combustible materials in building facade systems, it was clear the market needed a breakthrough technology.

Effisus ProFlex FR membrane is a prime example of a cutting-edge solution that effectively addresses the challenges of sealing an interface while considering both elongation and fire safety in the sealing of the facade.

This multi-layered, fire-rated, weatherproofing elastic membrane boasts an impressive 200% elongation capacity, exceptional resistance to puncture, and outstanding mechanical resistance, with high tensile and tear strength. Its fire performance is rated at B-s3 d0 according to BS EN 13501-1.
