lufttäthetsåtgärder

Lufttäthetsåtgärder refer to actions and strategies implemented to improve the airtightness of buildings. The primary goal of these measures is to prevent uncontrolled air leakage through the building envelope, which is the boundary separating the conditioned interior space from the unconditioned exterior. Uncontrolled air leakage can lead to various problems, including energy loss, reduced indoor air quality, moisture issues, and decreased thermal comfort.

Implementing lufttäthetsåtgärder involves identifying and sealing any gaps, cracks, or openings in the building's structure. This can include areas around windows and doors, joints between walls and roofs, penetrations for pipes and electrical wiring, and other potential pathways for air to escape or enter. Common materials used for sealing include tapes, membranes, sealants, and specialized coatings.

The benefits of effective lufttäthetsåtgärder are significant. By reducing air leakage, buildings become more energy-efficient as less heated or cooled air escapes, leading to lower energy consumption for heating and cooling. Improved airtightness also contributes to better control over indoor air quality by preventing the infiltration of outdoor pollutants, allergens, and dust. Furthermore, it helps to maintain a more stable and comfortable indoor temperature and can mitigate risks of moisture-related damage such as mold growth. Building codes in many regions now specify requirements for airtightness, and testing methods like blower door tests are often used to verify compliance.
