Vapour Control Layer

A vapour control layer restricts the movement of warm, moist air from inside a property into the fabric of the building. Our Passive Purple liquid vapour control range is applied with an airless sprayer, or roller, and dries to an airtight flexible coating. We have a range of tub sizes from 3.9Kg to 11.4kg available for you to purchase!

With excellent adhesion on different surfaces, such as concrete, brick and wood, our Passive Purple breathable vapour control layers can also be used on all wall and floor connections and joints.

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