Ånggenomsläppligt

Ånggenomsläppligt is a Swedish term that describes a material's ability to allow water vapor to pass through it. This property is crucial in many construction and textile applications to manage moisture. A material that is ånggenomsläppligt permits the diffusion of water vapor, preventing its accumulation within structures or fabrics.

In building materials, ånggenomsläppligt membranes are used in roofs, walls, and floors. These membranes help to regulate humidity, preventing condensation and the potential for mold growth or material degradation. They allow moisture that might otherwise become trapped inside a building to escape outwards. The degree of ånggenomsläpplighet is often measured using specific tests and standards to ensure effective performance.

Similarly, in the textile industry, ånggenomsläppligt fabrics are essential for sportswear, outdoor gear, and workwear. These materials allow perspiration to escape from the body, keeping the wearer dry and comfortable. Fabrics that are not ånggenomsläppligt can lead to a clammy feeling and reduced thermal regulation. The concept is distinct from being waterproof, which refers to the ability to prevent liquid water from passing through. A material can be both waterproof and ånggenomsläppligt, a combination often sought for high-performance applications.
