Waterproof Breathable Membrane
Breathable membranes are water-resistant but vapour permeable which means that they can protect your building from damp related issues while releasing any surplus moisture vapour into the air. They are also able to prevent penetration by external environmental factors including snow, wind and rain and they keep out contaminants such as dust and dirt.
Product Parameter
Three-layer vapour-permeable roof membrane. Made of two layers of polypropylene non-woven and special functional film which ensures high vapour permeability and water sealing of the underlay. Owing to its high vapour permeability, it can be applied directly on insulation and consequently a venting slot is not required between the membrane and the thermal insulation.
