ilmatiiviiseen

Ilmatiiviiseen is a Finnish term that translates to "airtight" or "impermeable to air" in English. It refers to a state of being sealed in such a way that no air can pass through. This concept is crucial in various fields, particularly in construction and engineering, to control air infiltration and exfiltration.

In building design, achieving an ilmatiiviiseen envelope is a key objective for energy efficiency. A well-sealed building prevents unwanted drafts and heat loss during colder months, and also stops conditioned air from escaping in warmer weather. This can lead to significant reductions in heating and cooling costs and improve occupant comfort by minimizing temperature fluctuations. Materials like airtight membranes, sealants, and tapes are used to create this barrier.

Beyond buildings, the principle of ilmatiiviiseen is applied in packaging to preserve the quality of food and other sensitive products. Airtight packaging prevents oxygen and moisture from entering, which can cause spoilage or degradation. Similarly, in industrial processes, maintaining an ilmatiiviiseen environment might be necessary to prevent contamination or control specific atmospheric conditions. The effectiveness of an ilmatiiviiseen system is often measured by its air leakage rate, with lower rates indicating better performance.
