Eristyskerroksen
Eristyskerroksen (insulation layer) is the layer of insulating material incorporated into a building envelope to reduce heat flow between interior and exterior environments. It is commonly placed in exterior walls, roof assemblies, floors above unheated spaces, and foundations, and may be used in both new construction and renovations. The primary purpose is to improve energy efficiency, maintain comfortable indoor temperatures, and reduce heating and cooling costs. It also affects acoustic performance and, depending on the material, fire resistance and vapor control.
Materials vary widely. Mineral wool and glass wool provide fire resistance and moisture tolerance; polystyrene boards
Design and installation considerations include achieving continuous insulation to minimize thermal bridges, proper detailing at joints,
In Nordic and other cold climates, eristyskerroksen plays a central role in energy efficiency, often combined
