Airtightness systems

An airtight building envelope prevents draughts and is a key element in energy saving and durability. It also improves sound insulation and is a particularly cost-effective energy-saving measure. All certified airtightness systems have been tested for functionality in a realistic setting. They offer a secure connection to other airtightness layers and come with complete and easy-to-understand installation instructions. You can find more information on the airtightness of buildings on
