Air & Weather Tightness
Creating an air and weather tight envelope is an essential element to a high-performing home. Our membranes, tapes and sealants are designed to work together to stop air from escaping – achieving that cocoon-like haven.
How the SIGA products work
The SIGA product range is designed to work as a family of membranes, tapes and sealants to achieve a total air and windproof building envelope for residential and commercial buildings. Their products have been developed for specific areas of the building, the roof, and the external part of the building.
