sisäeristeinä

Sisäeristeinä refers to thermal insulation materials used on the interior side of a building's construction. These materials are installed within the walls, floors, or ceilings to reduce heat transfer between the interior and exterior environments. The primary purpose of interior insulation is to improve the building's energy efficiency by minimizing heat loss during colder months and heat gain during warmer months, thereby reducing heating and cooling costs.

Various materials can be employed as sisäeristeinä. Common examples include mineral wool, which is made from rock or glass fibers, and cellular plastics like polystyrene or polyurethane foams. Natural materials such as wood fiber, cork, or sheep wool are also gaining popularity as eco-friendly alternatives. The selection of the appropriate insulation material depends on factors like thermal conductivity (R-value), moisture resistance, fire safety, cost, and environmental impact.

Proper installation is crucial for the effectiveness of sisäeristeinä. Air gaps or thermal bridges can significantly compromise the insulation's performance. Therefore, careful attention is paid to sealing all joints and penetrations to create a continuous thermal barrier. Furthermore, the placement of vapor barriers is often considered to manage moisture within the building envelope, preventing condensation and potential damage to the structure. Interior insulation can sometimes be a more straightforward solution in renovation projects where exterior modifications are limited or undesirable.
