Product Description

DuPont is bringing building breather membranes to next level of protection, with flame retardant Tyvek FireCurb, enabling up to Euroclass B (EN13501-1). When flames meet Tyvek FireCurb, they literally stop, die down and go out. The new patented technology adds flame retardancy to the well-known properties of Tyvek for even more comprehensive protection of walls and roofs.

DuPont Tyvek FireCurb 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 takes the airtight and watertight yet vapour-open breather membranes of Tyvek membranes and adds flame retardancy properties that can significantly increase building safety. A flame retardant membrane can help slow or prevent the spread of flames, improving evacuation time for occupants and also helping to increase the fire rating of wall elements. Suitable for use in all building types, from bungalows to high-rises, Tyvek FireCurb offers an outstanding long-term protection solution you can trust.
