Airtightness Tapes & Membranes

We have created a range of air tightness products to complement all aspects of building with our systems. Our range of air tightness products covers all the areas needed to give you the best air testing results possible. From simple vapour control layers and breather membranes to more intelligent variable membranes, these are the products to ensure your building is dry and air tight. Whether you are building with timber frame or masonry we have all the tapes, sealants and accessories to ensure your building is as energy efficient as possible.
