DuPont™ Tyvek® FireCurb® breather membrane
Product Code:
Tyvek® FireCurb® breather membrane: a flame-retardant lightweight membrane based on DuPont™ patented technology, enabling reaction to fire classification of Euroclass B-s1,d0 (EN 13501-1) suited for fire risk averse installations, high-rise and higher risk buildings, self-extinguishes when ignited. It uses a halogen-free flame-retardant coating to reduce the formation of droplets and smoke with minimal environmental impact.
Description
DuPont™ Tyvek® FireCurb® breather membrane which inherited prominent properties of Tyvek® brand, being vapour-open, watertight, and durable, with added flame retardancy properties that could significantly increase building safety. Suitable for use in all building types, from low-rise, high-rise to higher risk buildings, Tyvek® FireCurb® breather membrane offers an outstanding fire rated weatherproofing solution you can trust.
When considering standardised testing and classification criteria for construction products through the EN 13501-1, classes are described by letters. The first letter gives a classification based on the combustibility and contribution to fire: A1 and A2 is non-combustible, B till E go from very limited to medium contribution to fire, and F means high contribution and easily flammable.
In addition, EN 13501-1 determines, development of smoke and severity of burning droplets falling off the material. The best possible class being s1 for no/hardly any smoke and d0 for no-droplets. Hence, a product can be said to perform to for e.g. class B-s1,d0 or class A2-s1,d0 and so forth and so on. Different test regimes of EN 13501-1 standard apply to different classes, for more details, please take specialists advice.
DuPont™ Tyvek® FireCurb® breather membrane lightweight (with 68 g/m² mass per unit area to EN 1849-2), fire retardant performing to Euroclass B-s1,d0 (EN 13501-1) is a membrane that self-extinguishes when subject to flame. It uses a halogen-free flame-retardant coating to reduce the formation of smoke (s1 – smoke emissions absent or very little) and droplets (d0 – no burning droplets) with minimal environmental impact. Holds independently verified documentation on environmental credentials – environmental product declaration (EPD).
