Air tightness measurements with blower door measurement method

In well-insulated buildings, up to 60 % of heating energy can be lost through gaps and cracks in the building envelope. Energy-efficient construction can therefore only be achieved with a high degree of airtightness of the building envelope. In addition, this prevents structural damage due to condensation as well as the penetration of drafts, noise or odors.
