Iain Fairnington, our Technical Director for the Group explains, “BS EN 13823:2010 evaluates the performance of products in relation to heat & smoke production, lateral flame spread and the presence of flaming droplets or particles. Under these test conditions Wraptite achieves a Class B-s1-d0 rating, the highest possible for a polypropylene membrane. This classification gives specifiers absolute confidence in the membranes performance in the event of fire.”
Wraptite combines the important properties of vapour permeability and airtightness in one self-adhering membrane. Wraptite has received BBA certification for use in both roofs and in walls behind rain screen cladding making it an ideal choice for commercial projects with large uninterrupted façades.
