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.
4 major advantages of airtight buildings
1. Greater living comfort: Live without drafts. Airtight buildings keep heat and cold outside, as well as traffic noise and air pollution.
2. Save money, protect the climate: Energy consumption for heating and cooling of an airtight building is significantly lower than traditional structures, and as a result, reduces climate-damaging CO2 emissions.
3. Preserve value: Airtight buildings are protected from wind, rain, drifting snow, insects and building damage caused by condensation and mold.
4. Active house feasible: The low energy consumption of an airtight building facilitates self-sufficiency with renewable energy. That’s how easy it is to turn a building into an active building.
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.
To build a healthy and comfortable indoor environment, you need a good thermal envelope. Learn what a thermal envelope is, what functional layers it is made of and why thermal insulation is so important for saving energy.
