DuPont™ Tyvek® Trifecta™

Tyvek® Trifecta™ is a non-combustible and robust breather membrane suited 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.​

 

Tyvek® Trifecta™ doesn’t produce droplets or emit smoke when subjected to flame, making it a great choice for fire risk averse build-up designs. It is engineered for fast and easy installation with non-combustible A2 tape.

 

Airtight and watertight yet vapour-open, the Tyvek® Trifecta™ breather membrane also contributes to energy conservation and climate control, improving the comfort of occupants and contributing to higher internal air quality.​

 

Tyvek® Trifecta™ is the unique long-term protection solution every builder can trust.
