Lisäeristekerrokset

Lisäeristekerrokset refers to additional layers of insulation added to a building to improve its thermal performance. These layers are typically applied to existing structures, often during renovations or retrofits, to enhance energy efficiency and occupant comfort. The primary goal is to reduce heat loss in colder months and heat gain in warmer months, thereby lowering heating and cooling costs.

Common materials used for lisäeristekerrokset include mineral wool, polystyrene boards (EPS or XPS), polyurethane foam, and natural insulation materials like cellulose or wood fiber. The specific type of material chosen depends on factors such as the location of application (walls, roofs, floors), cost, environmental impact, and desired thermal resistance (R-value).

The application methods for lisäeristekerrokset vary. For external walls, insulation boards can be attached directly to the existing facade and then covered with a new cladding or render. Alternatively, insulation can be blown into existing cavities or applied as a spray foam. For roofs, insulation can be added above or below the existing roof structure. Floors can be insulated by adding layers beneath the floor finish or by insulating the basement or crawl space.

Implementing lisäeristekerrokset can significantly improve a building's energy performance, reduce its carbon footprint, and enhance indoor air quality by preventing drafts and condensation. It is an important strategy in sustainable building practices and energy conservation efforts.
