Add Built-in Safety with a Fire Retardant Breather Membrane

Tyvek® FireCurb® breather membrane (formerly called Tyvek® FireCurb® Housewrap, is only a name change) is a fire-retardant breather membrane for commercial and residential buildings that uses new, patented technology.


DuPont™ Tyvek® FireCurb® Breather Membrane

DuPont™ Tyvek® FireCurb® breather membrane is a lightweight, advanced, fire retardant membrane that self-extinguishes when ignited. It uses a halogen-free flame-retardant coating to reduce the formation of droplets and smoke with minimal environmental impact.

Tyvek® FireCurb® breather membrane takes the airtight and watertight yet vapour-open breather membranes of Tyvek® membranes and adds flame retardancy properties that can significantly increase building safety. Suitable for use in all building types, from bungalows to high-rises, Tyvek® FireCurb® breather membrane offers an outstanding long-term protection solution you can trust.
