ilmavuotoestejärjestelmä

An ilmavuotoestejärjestelmä, which translates to "air leakage barrier system" in English, is a construction method or component designed to prevent uncontrolled air infiltration and exfiltration through the building envelope. Its primary function is to create a continuous and airtight layer within the building's structure, ensuring that air movement is managed and controlled. This system is crucial for achieving energy efficiency in buildings, as it significantly reduces heat loss in colder climates and heat gain in warmer climates by minimizing the transfer of conditioned air to the outside and unconditioned air to the inside.

The implementation of an ilmavuotoestejärjestelmä can involve various materials and techniques. These may include specialized membranes, tapes, sealants, and carefully designed construction details at junctions between different building elements such as walls, roofs, floors, windows, and doors. The effectiveness of the system relies on the meticulous application and continuity of these components, leaving no gaps or openings where air could escape or enter.

Beyond energy savings, a well-installed ilmavuotoestejärjestelmä contributes to improved indoor air quality by preventing the ingress of pollutants, dust, and moisture from the exterior. It also plays a vital role in protecting the building structure itself by preventing moisture-laden air from condensing within wall cavities, which can lead to mold growth and material degradation. Consequently, such systems are increasingly becoming a standard requirement in modern building codes and certifications focused on sustainable and high-performance construction.
