ilmatiiveydellä

Ilmatiiveydellä refers to the property of a building or its components to resist unintended air leakage. This means preventing air from passing through the building envelope, which includes walls, roofs, floors, windows, and doors. Achieving good ilmatiiveydellä is crucial for several reasons related to energy efficiency, comfort, and building health.

A primary benefit of ilmatiiveydellä is improved energy performance. Uncontrolled air leakage can account for a significant portion of a building's heating and cooling energy loss. By sealing gaps and cracks, less conditioned air escapes and less unconditioned air enters, reducing the workload on HVAC systems. This leads to lower energy bills and a smaller environmental footprint.

Furthermore, ilmatiiveydellä enhances indoor comfort. Air leaks can create drafts, uneven temperatures, and cold spots within a building, making it feel uncomfortable. A well-sealed building maintains more stable internal temperatures and reduces drafts, creating a more pleasant living or working environment.

Ilmatiiveydellä also plays a role in maintaining good indoor air quality and protecting the building structure. Air leakage can carry moisture, dust, and pollutants from the outside into the building, potentially leading to health problems and material degradation. By controlling air movement, these unwanted elements can be better managed. Specialized testing methods, such as a blower door test, are often used to measure and quantify the level of ilmatiiveydellä in a building.
