Sisäeristeissä

Sisäeristeissä refers to insulation materials installed on the interior side of a building's walls. This method is often chosen when exterior insulation is not feasible, such as in historic buildings with preserved facades or in cases of complex building designs. Interior insulation can also be a solution for renovations where altering the exterior is undesirable or restricted.

The primary purpose of sisäeristeissä is to improve a building's thermal performance, reducing heat loss in winter and heat gain in summer. This leads to lower energy consumption for heating and cooling, increased comfort for occupants, and a reduced environmental impact. By adding insulation on the inside, the interior space is effectively reduced, which is a consideration for homeowners.

Common materials used for sisäeristeissä include mineral wool, wood fiberboards, and various types of foam insulation. The choice of material depends on factors such as thermal resistance requirements, moisture management properties, fire safety, and cost. A critical aspect of installing interior insulation is managing moisture to prevent condensation within the wall structure. This typically involves the careful installation of a vapor barrier on the warm side of the insulation to prevent moist indoor air from reaching colder surfaces where it could condense. Proper ventilation of the interior space is also essential. While effective, sisäeristeissä can present challenges related to thermal bridging, where heat can bypass the insulation through structural elements, and can affect the aesthetic and functional layout of rooms.
