Hengittävyyttä

Hengittävyyttä is a Finnish term that translates to "breathability" in English. It refers to the ability of a material to allow air and water vapor to pass through it. This property is particularly important in textiles, footwear, and construction materials.

In the context of clothing and footwear, breathability is crucial for comfort. Breathable materials allow sweat to evaporate, preventing the buildup of moisture and heat against the skin. This helps regulate body temperature and reduces the risk of chafing and discomfort, especially during physical activity. Fabrics like Gore-Tex are known for their breathability, allowing perspiration to escape while preventing external water from entering.

In construction, breathable materials are used in walls, roofs, and insulation. These materials allow moisture vapor from inside a building to escape to the outside, preventing condensation and the potential for mold growth and structural damage. Proper breathability in buildings contributes to a healthier indoor environment and increases the longevity of the structure.

The concept of breathability is often measured by specific tests that quantify the rate of air or water vapor transmission through a material. These measurements help manufacturers and consumers understand and compare the performance of different products. Factors such as the material's composition, weave or knit structure, and any applied coatings can affect its breathability.
