What Is A Breathable Membrane?

A breathable membrane is a water-resistive and vapor-permeable layer used in roof and wall systems. It helps reduce rain, snow and wind entry from the outside, while allowing trapped moisture vapor inside the building envelope to move outward. This balance is important for timber frame construction, insulated wall systems and roofing projects where moisture control affects long-term performance.

International buyers may search for the same product as waterproof breathable membrane, waterproof breathable fabric, breathable membrane, housewrap, building wrap, water-resistive barrier or WRB. Kedebon uses these terms clearly so buyers can match the product with their local specification language.

How It Works In Roof And Wall Systems

Water-Resistive Barrier

Installed behind cladding or under roofing materials to help block external water entry and protect sheathing or insulation layers.

Vapor Permeable Layer

Allows moisture vapor to pass through, supporting drying performance in wall cavities, timber frame projects and insulated assemblies.

Wind And Dust Protection

Helps improve the stability of the building envelope by reducing air movement, dust entry and exposure during installation.

Typical Applications

Housewrap and building wrap for exterior wall protection.
Water-resistive barrier (WRB) for timber frame and light steel frame buildings.
Roof underlayment for pitched roof and ventilated roof systems.
Facade backing layer behind cladding, siding and panel systems.
OEM and private label roll supply for distributors, building material brands and project contractors.
