Tyvek® Trifecta™ is a non-combustible breather membrane designed to provide all the benefits of a standard Tyvek® breather membrane, but with A2-s1, d0 Class Fire Performance to the current European Fire Classification Standard EN 13501-1.
It surpasses current UK Building Regulations, which require membranes to meet Class B. By exceeding minimum standards, customers can positively contribute to building safety, an area of our industry which has undergone a vast shift in recent years.
The latest generation breather membrane was recognised at the 2024 R&D 100 Awards, winning the Mechanical/Materials category. For six decades, the R&D 100 Awards have been a benchmark of achievement in science and technology, often referred to informally as ‘The Oscars of Innovation.’
Tyvek® Trifecta™ is installed on the cold side of external wall insulation, and also possesses excellent moisture management properties with class W1 water resistance to EN13859-2. Coupled with the product’s low vapour resistance and up to 12 months UV resistance, this makes its performance suitable as a secondary weather protection layer in external wall systems, with additional temporary rain protection during construction.
The breather membrane is supplied in a lightweight and convenient roll size of 1.5m x 25m, making it fast and easy to install on site.
DuPont™ Tyvek® Trifecta™ complements the DuPont™ AirGuard® A2 FR AVCL to create a complete A-rated membrane system. The DuPont™ AirGuard® FR System Tape further enhances the system's fire and moisture protection capabilities, with a 25-year limited warranty available.
