Eristelevyjä

Eristelevyjä are rigid boards used for thermal insulation in buildings. They come in a range of materials, including expanded polystyrene (EPS), extruded polystyrene (XPS), polyiso insulation (PIR), polyurethane (PU), mineral wool, wood fibre, and cork. These boards are commonly used in external wall insulation systems, interior wall insulation, roof and attic insulation, and floor insulation, helping to reduce heat loss and improve energy efficiency.

The choice of material affects thermal performance, fire safety, moisture handling, and durability. Thermal conductivity (lambda) and thickness determine the overall insulation value, often expressed as a U-value or R-value. Mineral wool and wood fibre boards typically offer good fire resistance and moisture tolerance, while polystyrene boards provide high insulation with lower cost but may require additional fire protection. Some foam boards may have environmental or health considerations related to blowing agents or emissions. Installation practices, including proper adhesion, mechanical fixings, taping of joints, and avoidance of thermal bridges, are crucial for performance.

Environmental and safety aspects are important. Production impacts vary by material, and many eristelevyjä are designed for recyclability or reuse at end of life. In Nordic climates, moisture management and vapor control are essential, so the choice of board often balances insulation needs with the building’s moisture strategy and local building regulations. In Europe, eristelevyjä intended for building use are typically manufactured to standardized specifications and bear CE markings, indicating conformity with relevant thermal insulation and safety standards.

In summary, eristelevyjä are versatile insulation solutions chosen for material properties, application area, and climate, with attention to installation quality and environmental considerations.
