Ilmatiheydestä
Ilmatiheydestä, or air tightness, refers to the quality of a building or structure to prevent unintended air leakage. This leakage can occur through cracks, gaps, and openings in the building envelope, which includes walls, roofs, floors, windows, and doors. Maintaining good ilmatiheydestä is crucial for several reasons, including energy efficiency, indoor air quality, and thermal comfort.
When a building is not airtight, heated or cooled air can escape to the outside, leading to
Beyond energy and comfort, ilmatiheydestä also impacts indoor air quality. Uncontrolled air infiltration can bring in
Assessing and improving ilmatiheydestä is often done through blower door tests. These tests measure the overall
