Revolutionising Protection of the Building Substrate

Traditional breather papers and wraps create obvious paths for moisture to reach-and compromise-the substrate. Our seamless, liquid applied air and water-resistive barriers stop moisture in its tracks keeping your substrate protected as well as air tight. Whether you are applying it under any one of our external wall insulation (EWI) systems or a non-EWI wall assembly, we've got your building substrate covered!

Thinking Outside the Box for Protection of Building Substrates

Aquaflash& Backstop air and moisture barriers deliver a protected envelope even before your EWI or other cladding system is installed giving ultimate piece of mind.
