Polyuretaanieristeellä

Polyuretaanieristeellä is a Finnish term referring to insulation made from polyurethane. Polyurethane foam is a versatile polymer material produced by reacting polyols and isocyanates. It is widely used in construction for its excellent thermal insulation properties. The foam can be applied in various forms, including spray foam, rigid boards, and pre-formed panels, making it adaptable to different building applications.

The primary advantage of polyurethane insulation is its high R-value, which indicates its resistance to heat flow. This means it can effectively reduce heat loss in winter and heat gain in summer, contributing to energy efficiency and lower heating and cooling costs. Polyurethane foam also has a closed-cell structure, which provides a good barrier against moisture and air infiltration, further enhancing its performance and preventing issues like mold growth.

In construction, polyuretaanieristeellä is commonly used to insulate walls, roofs, floors, and foundations. Spray polyurethane foam can be applied directly to surfaces, expanding to fill cavities and creating a seamless insulating layer. Rigid polyurethane boards are often used for insulating exterior walls and roofs, providing a consistent and durable insulation solution. The material is also utilized in appliances like refrigerators and freezers to maintain low temperatures efficiently. While effective, the installation of spray foam requires specialized equipment and trained professionals due to the chemicals involved.
