Lämpöeristykset, or thermal insulation in English, refers to materials and methods used to reduce heat transfer between objects or spaces. The primary purpose of thermal insulation is to keep heat where it is wanted and out of where it is not. This is crucial for energy efficiency in buildings, where insulation helps maintain comfortable indoor temperatures, reducing the need for heating in winter and cooling in summer. This leads to lower energy consumption and reduced greenhouse gas emissions.

The effectiveness of thermal insulation is measured by its thermal resistance, commonly known as the R-value. A higher R-value indicates better insulation. Different materials have varying R-values, and the choice of insulation depends on factors such as cost, desired performance, installation method, and environmental considerations. Common insulating materials include fiberglass, mineral wool, foam boards, cellulose, and natural fibers like sheep's wool or cotton.

In construction, insulation is typically installed in walls, roofs, floors, and around pipes and ducts. Proper installation is vital to prevent thermal bridging, which are areas where heat can more easily escape or enter. Beyond buildings, thermal insulation is also used in appliances like refrigerators and ovens, in industrial processes to maintain specific temperatures, and in transportation to protect goods from temperature fluctuations. The development of new and improved insulation materials continues to be an active area of research, aiming for higher performance, greater sustainability, and lower costs.
