Eristemateriaalilevyjä

Eristemateriaalilevyjä, often translated as insulation board or insulating panel, are building materials primarily used for thermal insulation in construction. They are designed to reduce heat transfer, contributing to energy efficiency and improved indoor comfort in buildings. These boards are manufactured from various materials, each offering different properties and applications. Common types include rigid foam boards made from polystyrene (EPS and XPS), polyurethane (PUR/PIR), and mineral wool boards.

Polystyrene foam boards, such as expanded polystyrene (EPS) and extruded polystyrene (XPS), are widely used due to their lightweight nature, good insulation value, and moisture resistance. EPS is typically white and used for general insulation purposes, while XPS is denser and often colored, offering higher compressive strength and better moisture resistance, making it suitable for applications like foundations and inverted roofs. Polyurethane and polyisocyanurate (PIR) boards offer excellent thermal performance with relatively thin profiles, making them ideal for applications where space is limited. Mineral wool boards, made from rock or slag, provide good thermal insulation along with fire resistance and sound absorption qualities.

The selection of eristemateriaalilevyjä depends on factors such as the required R-value (thermal resistance), moisture exposure, fire safety regulations, structural load-bearing requirements, and cost. They are used in a variety of building elements, including walls, roofs, floors, and foundations, to minimize heat loss in winter and heat gain in summer, thereby reducing energy consumption for heating and cooling. Installation methods vary but generally involve adhering or mechanically fixing the boards to the building structure.
