Weatherproof Membrane

A weatherproof membrane restricts the movement of warm, moist air from inside a property into the fabric of the building. Our Passive Purple and other liquid weatherproof membrane ranges are applied with an airless sprayer or roller and dries to an airtight flexible coating. With excellent adhesion on different surfaces, such as concrete, brick and wood, our Passive Purple breathable vapour control products can be used on all wall and floor connections and joints.

Our liquid membranes and vapour control layer products are cost-effective, easy to apply, VOC-free and extremely tough with breathable vapour control to give your external facade UV protection.
