Lisäeristysjärjestelmät

Lisäeristysjärjestelmät refers to external thermal insulation composite systems (ETICS) used in building construction. These systems are designed to improve the thermal performance of existing buildings by adding an insulating layer to the exterior walls. The primary goal is to reduce heat loss in winter and heat gain in summer, thereby enhancing energy efficiency and occupant comfort.

An ETICS typically consists of several components. A layer of insulation material, commonly expanded polystyrene (EPS), mineral wool, or polyurethane foam, is attached to the external facade of the building using adhesive and mechanical fasteners. Over this insulation layer, a reinforced base coat is applied, embedding a mesh fabric for structural integrity and crack resistance. Finally, a decorative and weather-resistant finish coat is applied to protect the system from the elements and provide the desired aesthetic appearance.

The application of ETICS is a significant method for renovating older buildings that may have insufficient or outdated insulation. By upgrading the thermal envelope, these systems contribute to lower energy consumption for heating and cooling, reducing greenhouse gas emissions. Furthermore, ETICS can improve the sound insulation of the building and protect the underlying structure from moisture and weathering. Proper installation by qualified professionals is crucial to ensure the long-term performance and durability of the system.
