Rakennuseristeet

Rakennuseristeet are materials used in construction to reduce heat transfer. Their primary function is to improve thermal insulation, which helps maintain a comfortable indoor temperature and reduces energy consumption for heating and cooling. Effective insulation also contributes to soundproofing and can help manage moisture within building structures.

Various types of rakennuseristeet are available, each with distinct properties and applications. Common examples include mineral wool, such as glass wool and stone wool, which are known for their fire resistance and sound absorption qualities. Foamed plastics, like expanded polystyrene (EPS) and extruded polystyrene (XPS), offer excellent thermal resistance and moisture resistance, making them suitable for foundations and walls. Polyurethane foam (PUR) and polyisocyanurate (PIR) are also widely used, often in spray or board form, providing high insulation values. Natural materials like cellulose, cork, and sheep's wool are also employed as sustainable insulation options.

The selection of rakennuseristeet depends on factors such as the specific building component being insulated (walls, roofs, floors), the required thermal performance (U-value), fire safety regulations, environmental considerations, and budget. Proper installation is crucial to ensure the effectiveness of the insulation and prevent thermal bridging, which can compromise the overall energy efficiency of the building. By reducing the need for artificial heating and cooling, rakennuseristeet play a significant role in enhancing building performance and sustainability.
