Kattoeristeinä

Kattoeristeinä refers to the use of materials as insulation within a roof structure. This is a crucial aspect of building construction, aimed at reducing heat transfer between the interior of a building and the exterior environment. Effective roof insulation helps maintain comfortable indoor temperatures, lowers energy consumption for heating and cooling, and can contribute to soundproofing.

Various materials are employed as kattoeristeinä, each with distinct properties regarding thermal conductivity, moisture resistance, and fire retardancy. Common examples include mineral wool (rock wool or glass wool), which is a non-combustible material known for its good thermal and acoustic insulation properties. Another popular option is foam insulation, such as polyurethane foam (PUR) or polystyrene foam (EPS/XPS), which offers high thermal resistance with relatively thin layers. Natural materials like wood fiber or cellulose are also used, often favored for their sustainability and breathability.

The installation of kattoeristeinä typically involves filling the spaces between roof rafters or trusses. Careful attention is paid to ensuring a continuous layer of insulation, avoiding thermal bridges which can compromise the system's effectiveness. Vapor barriers are often integrated to prevent moisture from the interior air from condensing within the insulation, which could degrade its performance and lead to structural damage. The choice of kattoeristeinä and its installation method depend on factors such as climate, building type, and local building regulations.
