hengittävässä

Hengittävässä is a Finnish term that translates to "breathable" in English. It describes materials or structures that allow air to pass through them. This property is important in various applications, particularly in textiles, construction, and packaging.

In textiles, breathable fabrics are designed to permit the passage of moisture vapor away from the skin while preventing liquid water from entering. This helps to regulate body temperature and maintain comfort, making such materials ideal for activewear, outdoor clothing, and bedding. Breathability in fabrics is often measured by specific tests like the Moisture Vapor Transmission Rate (MVTR).

In construction, breathable building materials, such as certain types of insulation, membranes, and wall finishes, allow moisture to escape from within the building envelope. This helps to prevent condensation, mold growth, and structural damage. This is crucial for maintaining a healthy indoor environment and prolonging the lifespan of buildings.

Breathable packaging is used for certain food items and other products that require air circulation to maintain freshness or prevent spoilage. For example, some fruit and vegetable packaging incorporates breathable films to control the atmosphere inside and extend shelf life. The concept of "hengittävässä" is fundamentally about controlled air exchange.
