lisäeristön

Lisäeristö, often translated as additional insulation or secondary insulation, refers to any insulation material or system added to an existing structure to improve its thermal performance. This is typically done to upgrade older buildings that were not originally constructed with modern insulation standards in mind, or to meet new energy efficiency requirements. The primary goal of lisäeristö is to reduce heat transfer, keeping buildings warmer in the winter and cooler in the summer, which in turn leads to lower energy consumption for heating and cooling.

Common methods for implementing lisäeristö include adding insulation to attics, crawl spaces, and basements, as well as insulating walls. For walls, this can involve blown-in insulation into existing cavities, adding rigid foam boards to the exterior or interior, or constructing new interior walls with insulation. The choice of material and method depends on factors such as the existing construction type, budget, and the desired level of thermal resistance (R-value). Proper installation is crucial to avoid thermal bridging and moisture issues. Lisäeristö is a key component of building renovations aimed at improving energy efficiency and occupant comfort.
