DuPont™ Tyvek® FireCurb® Housewrap the flame retardant breather membrane

With recent events and new regulations, fire retardant construction materials and methods are currently in the spotlight. Tyvek® FireCurb® Housewrap offers an innovative flame retardant technology, ideal for high rise buildings, for use with ventilated façades, and for wall membrane applications in timber frame constructions.

The housewrap reduces flammability by using a phosphorous containing agent, which forms a ‘char’ layer at the surface when in contact with an ignition source. This thin layer of carbonized polymer is highly resistant to burning and creates a barrier, thus slowing the release of flammable materials from the membrane into the fire. Starved of fuel, the flame spreads over the membrane more slowly, or not at all.

In addition, Tyvek® FireCurb® Housewrap produces less smoke if it does burn; helping those who may be attempting to escape a burning building. The housewrap also limits flame propagation between floors via the external envelope and offers extremely high levels of flame retardancy (up to Class B).

The flame retardant performance adds to the many highly-valued properties of DuPont™ Tyvek® breather membranes, such as long-term wind, water and weather protection, effective vapour diffusion and a significant contribution to energy efficiency and interior comfort.
