lisäeristysmateriaalien

Lisäeristysmateriaalit, often translated as additional insulation materials or supplementary insulation, refer to products used to enhance the thermal performance of existing building structures. These materials are applied to improve the energy efficiency of a building, reduce heating and cooling costs, and enhance indoor comfort by minimizing heat transfer. They are distinct from primary insulation systems and are often employed in renovation projects or to address specific thermal bridging issues.

Common types of lisäeristysmateriaalit include various forms of rigid foam boards, spray foam insulation, and mineral wool batts or boards. Rigid foam boards, such as polystyrene (EPS and XPS) or polyisocyanurate, are frequently used for their high R-value per inch and their ability to create a continuous insulation layer, particularly on exterior walls or foundations. Spray foam, either open-cell or closed-cell, offers excellent air sealing properties in addition to insulation, filling cavities and irregular spaces effectively. Mineral wool, made from rock or slag, provides good fire resistance and acoustic properties alongside its thermal insulation capabilities.

The application of lisäeristysmateriaalit can take various forms. They might be installed on the interior surface of existing walls, on the exterior before cladding, within roof structures, or around foundations. The choice of material and application method depends on factors such as the existing building construction, budget, desired R-value, moisture management considerations, and local building codes. Proper installation is crucial to maximize the benefits and prevent potential issues like moisture accumulation or mold growth. These materials play a significant role in the retrofitting of older buildings to meet modern energy performance standards.
