ITP have launched a new breather membrane providing a solution for high-performance wall construction.
FlameOut Breathe Class A has been developed to meet the growing demand for fire-safe, durable, and moisture-managing building envelope systems. Designed specifically for external wall applications, the heavyweight woven breather membrane combines vapour permeability, water resistance, and enhanced fire performance in a single robust product.
Installed on the cold side of insulation, FlameOut Breathe Class A allows moisture vapour to escape from the wall structure while helping to prevent the ingress of external moisture. This supports the long-term performance of insulated wall systems and contributes to a healthier, more durable building envelope. Its high-strength woven construction also provides excellent tensile strength, making it suitable for demanding façade and rainscreen applications.
ITP Sales Director, Matt Thompson quoted “A key feature of our new class A membrane is its exceptional fire performance. Independently tested to EN 13501-1, FlameOut Breathe Class A achieved an A2-s1,d0 classification when free-hanging.”
In addition to its fire performance, the membrane also offers high water resistance to EN 1928, helping protect external wall constructions from weather exposure while maintaining vapour permeability to support outward drying.
Suitable for residential, commercial, and high-rise developments, FlameOut Breathe Class A delivers a balanced combination of fire safety, weather protection, moisture control, and durability, making it an ideal choice for modern façade, cladding, and rainscreen systems. The product is CE certified, with a Declaration of Performance available on request.
ITP’s FlameOut Breathe Class A breather membrane is available in pallet quantities or individual rolls at 1.5 x 50m rolls, contact the sales team today on +44(0)1347 825200 before they sell out.
