A BBA-certified, Passivhaus Certified, ICC Certified airtight vapour control air barrier coating that is applied with an airless spray device on all areas of an external envelope (warm side of the insulation) of a building. This includes those difficult connection areas to the floor, wall, roof and joist. When used on the warm side of the insulation, it can be applied to either face of the external envelope. To install, ensure the material or surface is dust-free.
