DuPont has been a pioneer in fire safety for over 50 years and introduced its Tyvek® FireCurb® Housewrap breather membrane for buildings in 2013. As regulations catch up post Grenfell, and as most fires begin inside buildings, DuPont has since developed an airtight vapor control layer in its high performance AirGuard® range, to offer similarly advanced, non-toxic, fire-resistance with proven efficacy.
Now developers, designers and control officers can have confidence in a complete membrane and tape solution for durably enhanced fire safety in both the exterior and interior fabric of a building. While Tyvek® FireCurb® Housewrap forms a weather-protective, vapor-open lining behind ventilated facades, new DuPont™ AirGuard® A2 FR AVCL offers energy-saving, moisture management, improved interior air quality and climatic comfort, together with its added fire-retardant function.
Airtightness and vapour control
Tyvek® FireCurb® Housewrap utilizes DuPont's patented self-extinguishing technology. Its halogen-free coating limits the propagation of flames and the formation of droplets, while also minimizing smoke. DuPont™ AirGuard® A2 FR is truly fire-retardant and independently rated as Class A2. Along with Tyvek® 2060M Metallized Tape, DuPont now offers a complete A2 classified membrane and sealing system that surpasses existing regulations.
Correct installation is crucial, nonetheless. In addition to airtightness and vapour control, properly taped systems also help to reduce smoke penetration, a primary cause of casualties in a fire. DuPont also offers comprehensive guidance and support to ensure its products perform as designed. Suitable for application in any type of building, these robust products offer not only reliable performance, easy installation and full regulatory compliance, but a vital investment in greater safety and peace of mind, both during and after installation.
