A long-term and trustworthy protection solution, Tyvek® Trifecta A2 Fire Rated Breather Membrane is a 25m x 1.5m non-combustible and robust breather membrane that is fire retardant with an A2 European Classification. Suitable for high-rise and high-risk commercial and residential buildings with 3-in-1 underlaying properties of A2 (s1,d0), W1 and 0.416 MNsg / SD 0.08m, this membrane is both watertight and airtight yet also vapour open.
Designed to ensure fast and easy installation with non-combustible A2 tape, it allows unrestricted use for high-rise buildings, including height and proximity across the UK & Ireland. It doesn't produce droplets or emit smoke when subjected to flame, which makes it an ideal solution for fire-risk-averse build-up designs.
Able to withstand UV exposure for up to 12 months and with a W1 water resistance rating to EN 1928 (A) for effective weather protection, Tyvek® Trifecta contributes to energy conservation and climate control, improving the comfort of occupants and contributing to higher internal air quality. Its low vapour resistance also provides condensation control.?
Question:
Can this product be used internally on an external wall
Answer:
The DuPont Tyvek Trifecta A2 Fire Rated Breather Membrane is designed for application on external walls. It is a vapour permeable, airtight, and watertight membrane, providing excellent protection for your walls. However, it's typically used on the exterior side of the wall as it's designed to protect against outside elements. If you're looking for an internal application, I would advise checking if this product is suitable for your specific requirements or considering other products designed for internal use.
