Ilmantiiviitä

Ilmantiiviitä, often translated as air-tighteners or air sealants, refers to materials and techniques used to prevent uncontrolled air leakage through the building envelope. This leakage can occur through cracks, gaps, and penetrations in walls, roofs, and floors. The primary goal of ilmantiiviitä is to improve energy efficiency, enhance occupant comfort, and ensure proper functioning of the building's ventilation system.

Effective air sealing is crucial for maintaining a healthy indoor environment. By reducing air infiltration, it helps to keep out unwanted pollutants, allergens, and moisture. This, in turn, can prevent issues such as mold growth and improve indoor air quality. Furthermore, a well-sealed building envelope requires less energy for heating and cooling, as conditioned air is retained within the building and unconditioned air is kept out.

Common materials used for ilmantiiviitä include specialized tapes, membranes, caulks, and spray foams. These are applied to joints, seams, and around openings for windows, doors, pipes, and electrical outlets. The application process typically involves careful inspection of the building envelope to identify potential air leakage pathways. Professional installation is often recommended to ensure a continuous and effective air barrier.

The concept of ilmantiiviitä is closely linked to building codes and standards that specify requirements for airtightness. Many countries and regions have regulations in place to promote energy-efficient construction, and achieving a certain level of airtightness is often a mandatory part of these standards. Monitoring and testing, such as blower door tests, are used to verify the effectiveness of the air sealing.
