Rakennusairistelevyjä

Rakennusairistelevyjä, known in English as building insulation boards or sheathing boards, are construction materials used in buildings to provide thermal insulation, structural support, or a combination of both. These boards are manufactured from various materials, including wood fibers, mineral wool, foam plastics, and gypsum.

The primary function of rakennusairistelevyjä is to reduce heat transfer, thereby improving the energy efficiency of a building. This is crucial for maintaining comfortable indoor temperatures year-round and reducing heating and cooling costs. In addition to thermal insulation, some types of these boards offer acoustic insulation, dampening sound transmission between rooms or from the outside.

Structurally, certain rakennusairistelevyjä are designed to add rigidity and stability to building elements such as walls, roofs, and floors. They can act as bracing, distributing loads and preventing movement. The specific type of board chosen depends on its intended application, whether it's for exterior sheathing, interior wall lining, or attic insulation.

Common materials include wood fiberboards, which are known for their breathability and moisture-regulating properties, and foam boards like EPS (expanded polystyrene) or XPS (extruded polystyrene), valued for their high insulation performance and low weight. Mineral wool boards offer excellent fire resistance and acoustic properties. The selection of rakennusairistelevyjä in construction projects is guided by building codes, environmental considerations, and the desired performance characteristics for the building envelope.
