sisäänotettavaa

Sisäänotettavaa is a Finnish term that translates to "breathable" or "inhalable" in English. It is most commonly used in the context of materials and their ability to allow air or vapor to pass through them. This property is crucial in various applications, particularly in textiles, construction, and outdoor gear.

In textiles, breathability refers to a fabric's capacity to permit perspiration vapor to escape from the body, thus helping to regulate body temperature and prevent a clammy feeling. Materials like Gore-Tex are known for their breathable membranes, which can block liquid water from entering while allowing water vapor to exit. This is achieved through a microporous structure that is too small for liquid water droplets to pass through but large enough for water vapor molecules.

In construction, breathable materials are used in building envelopes to manage moisture. Wall assemblies that can "breathe" allow trapped moisture from inside the building to escape outwards, preventing condensation within the wall structure. This can help to maintain the integrity of building materials and prevent mold growth. Examples include certain types of insulation, vapor-permeable membranes, and breathable paints.

The concept of "sisäänotettavaa" is also relevant to air quality and environmental science, where it can refer to substances that can be inhaled. However, in common usage, it primarily denotes the permeability of materials to air or vapor, distinguishing them from impermeable or waterproof materials. The degree of breathability is an important factor when selecting materials for specific functional requirements, ensuring comfort, durability, and healthy indoor environments.
