Patent Pending, DuPont™ Tyvek® Trifecta™A2 Fire-Rated Breather Membrane compliments the DuPont™ AirGuard® A2 FR AVCL and completes the DuPont Fire Performance System. Available in the United Kingdom.

London, UK May 6, 2024 – DuPont Performance Building Solutions, a leading innovator in material science, has announced the launch of its latest generation breather membrane, Tyvek® Trifecta™. The innovative product offers exceptional fire safety and moisture protection, making it an ideal solution for external walls of high-rise buildings in a convenient and light-weight roll size of 1.5m x 25m. 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.

The Complete A-Rated Membrane System with a 25-year Limited Warranty

DuPont™ Tyvek® Trifecta™ compliments 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, helping to making it safe for use in all building types, including high-rise, single-story, dwellings, commercial projects, hotels, hospitals, and schools.

Tyvek Trifecta™ also features 12 months UV resistance, allowing for project time wiggle room while supporting a quality façade installation by protecting the structure during construction.

Advanced Protection against Moisture

Tyvek® Trifecta™ has excellent moisture management properties, with Class W1 water resistance to EN13859-2. Coupled with the product’s low vapour resistance, it offers an excellent solution as a secondary weather protection layer in external wall systems.

“Tyvek® Trifecta™ provides an outstanding solution to helps offer building owners fire safety protection of people using their buildings,” said Andrea Albert, Shelter Solutions EMEA Marketing Leader at DuPont.

“This product is a testament to our commitment to developing solutions that help enhance the fire safety and moisture protection standards of the construction industry, ” added Albert.

Europe has standardised testing and classification criteria for construction products through the European Standard EN 13501-1. Classes are described by letters. The first letter gives a classification based on the combustibility and contribution to fire: A1 and A2 is non-combustible, B till E go from very limited to medium contribution to fire, and F means high contribution and easily flammable. In addition, smoke development and severity of burning droplets falling off the material are determined. The best possible class being s1 for smoke and d0 for no droplets. Hence, a product can be said to perform to for e.g.  class B-s1,d0 or class A2-s1,d0 and so forth and so on. Different test regimes of EN 13501-1 standard are described below.

DuPont™ A2-s1,d0 fire rated non-combustible system for weatherproofing and condensation risk is designed to provide maximum fire safety and protection in the construction industry. It’s ideal for use in high-rise and higher-risk building applications.

DuPont™ Tyvek® Trifecta™ is an airtight, vapour permeable membrane that prevents water from penetrating the walls. It is a popular choice for weatherproofing and condensation risk mitigation in many risk-averse construction projects. DuPont™ Tyvek® Trifecta™ is installed on the cold side (outside) of the wall assembly, typically, between the external sheathing and mineral wool insulation.

The DuPont™ AirGuard® A2 FR AVCL provides resistance against water vapour, ensuring that trapping & accumulation of the moisture within walls and thermal insulation is prevented, which otherwise can result in structural damage and ineffective energy use. In addition, coupled with a cavity, it will provide thermal resistance. AirGuard® A2 FR AVCL is installed on the warm side (inside) of the wall assembly, typically, between the internal lining and structure.

Additionally, DuPont™ AirGuard® FR System Tape is used to seal horizontal and vertical laps, joints, junctions, around windows and doors, as well as sealing around penetrations such as pipework, wiring and structural elements.

AirGuard® FR System Tape is A2 fire rated product fully coherent with Tyvek® Trifecta and/or AirGuard® A2 FR AVCL, providing continuous and complete fire-rated system. It is an essential component in achieving the highest level of fire safety and contributes to bettering numerous other building performance aspects, such as airtightness, watertightness and smoke control.

Overall, the use of the DuPont™ A2 fire rated system gathered of Tyvek® Trifecta™, AirGuard® A2 FR AVCL, and AirGuard® FR System Tape is a highly effective, tested & proven, extremely reliable solution for improved fire safety in a wide variety of high-rise and higher-risk construction applications.
