lisäeristysjärjestelmä

Lisäeristysjärjestelmä, often translated as external thermal insulation composite system (ETICS) or EIFS, is a building facade insulation method. It involves applying a layer of insulation material, typically expanded polystyrene (EPS) or mineral wool, to the exterior of a wall. This insulation layer is then covered with a reinforcing mesh embedded in a base coat, followed by a final decorative render or cladding.

The primary purpose of a lisäeristysjärjestelmä is to improve the thermal performance of a building. By adding insulation to the exterior, it creates a continuous thermal barrier that significantly reduces heat loss in winter and heat gain in summer. This leads to increased energy efficiency, lower heating and cooling costs, and a more comfortable indoor environment.

Lisäeristysjärjestelmät are widely used in both new construction and building renovations. They can be applied to various substrates, including concrete, brick, and masonry. The system offers design flexibility, with a wide range of render finishes and colors available to suit aesthetic requirements. Additionally, the external application of insulation can help to protect the underlying structural wall from moisture and temperature fluctuations, potentially extending its lifespan. Proper installation by trained professionals is crucial to ensure the system's effectiveness and durability.
