õhutõkked

Õhutõkked are essential components in building construction, primarily functioning to control air leakage through the building envelope. Their main purpose is to prevent unwanted air movement between the conditioned interior of a building and the unconditioned exterior or unconditioned spaces within the building structure. This air leakage can lead to significant issues such as heat loss or gain, reduced insulation effectiveness, moisture problems, and decreased indoor air quality.

The installation of an effective air barrier system, which often includes an õhutõke, is crucial for energy efficiency. By minimizing air infiltration and exfiltration, õhutõkked help maintain stable indoor temperatures, reduce the load on heating and cooling systems, and ultimately lower energy consumption and associated costs. Furthermore, preventing moist interior air from migrating into wall cavities or attics is vital for avoiding condensation, which can lead to mold growth, rot, and structural damage.

Õhutõkked can be implemented using various materials and methods. Common examples include specialized membranes, rigid insulation boards with sealed joints, or even site-applied coatings. The specific material and system chosen depend on factors such as the building's design, climate, and local building codes. Proper sealing of all joints, penetrations, and transitions is paramount for the õhutõke to perform its intended function effectively, ensuring a continuous and airtight barrier.
