State of The Art:
The Airtight Building Envelope The airtightness of the building envelope is an important prerequisite for realizing modern energy concepts in new buildings, as much as for construction projects on existing buildings. It is also an essential aspect of quality assurance. Leaks in the building envelope increase ventilation heat losses. If ventilation equipment is installed in a building, an airtight building envelope is necessary to ensure flawless functioning of the installations, as uncontrolled air flow in the building prevents the optimal use of heat recovery systems and interferes with fresh and exhaust air supply. Preventing drafts significantly increases the indoor  comfort level. Structural damage caused by convective moisture transport into the building construction can be avoided. When rehabilitating existing buildings, an air barrier can be implemented to achieve current low-energy or even passive-house standards.
