lisäeristeinä

Lisäeristeinä refers to additional insulation materials used to improve the thermal performance of a building. These are distinct from the primary insulation layer and are often employed in renovation projects or in areas where the original insulation is insufficient. The goal of using lisäeristeinä is to reduce heat loss in winter and heat gain in summer, leading to lower energy consumption for heating and cooling, as well as enhanced indoor comfort.

Common types of lisäeristeinä include mineral wool, glass wool, rock wool, cellulose, expanded polystyrene (EPS), and extruded polystyrene (XPS). The choice of material depends on factors such as the application area, moisture resistance requirements, fire safety regulations, and cost. For example, in damp environments, materials with good moisture resistance like XPS might be preferred. In existing wall cavities, blowing insulation like cellulose or mineral wool can be installed without significant disruption.

The installation of lisäeristeinä can involve several methods. In existing attics or crawl spaces, loose-fill insulation can be blown or poured in. For walls, injection methods can be used to fill cavities, or exterior insulation can be added as a continuous layer. In some cases, interior insulation can be applied to walls, which may require careful consideration of moisture management to prevent condensation issues. Proper installation is crucial to avoid thermal bridging and ensure the effectiveness of the added insulation. The use of lisäeristeinä is a common strategy in energy efficiency upgrades for older buildings.
