Airtightness systems

The airtightness of a building is extremely important and is one of the five basic principles of the Passive house concept. If air flows through joints and cracks in a leaky building envelope, structural damage occurs and energy losses are unnecessarily high. In addition, sound insulation suffers and drafts reduce living comfort. The component database contains numerous certified airtightness systems; all products are accompanied by instructions for correct implementation. You can find out more about airtightness in buildings on the Passipedia knowledge platform.
