Lämpöeristevillat

Lämpöeristevillat, often translated as thermal insulation wools, are a common type of building insulation material. They are primarily made from mineral fibers, which are manufactured by melting and spinning rock or slag at high temperatures. The resulting fibers are then processed into various forms, such as batts, rolls, or loose-fill, for easy installation in buildings.

The main function of lämpöeristevillat is to reduce heat transfer, thereby improving a building's energy efficiency. They achieve this by trapping air within their fibrous structure. Air is a poor conductor of heat, so the numerous small air pockets created by the fibers significantly slow down the flow of heat from warmer areas to colder areas. This helps keep buildings warm in winter and cool in summer, reducing the need for artificial heating and cooling.

Common types of lämpöeristevillat include glass wool and mineral wool (also known as rock wool or slag wool). Glass wool is made from recycled glass and sand, while mineral wool is typically derived from basalt rock or industrial by-products like blast furnace slag. Both types offer excellent thermal insulation properties and are also known for their fire resistance and sound absorption capabilities.

When installing lämpöeristevillat, it is important to follow safety guidelines, as prolonged exposure to mineral fibers can cause skin and respiratory irritation. Proper personal protective equipment, such as gloves, masks, and eye protection, is recommended during handling and installation. The material is typically placed within wall cavities, attics, and floors to create a continuous thermal barrier.
