lämmöneristeiksi

Lämpöeristeiksi refers to thermal insulation materials used in construction and various industrial applications to reduce heat transfer. The primary function of thermal insulation is to minimize heat loss in cold conditions and heat gain in warm conditions, thereby improving energy efficiency and comfort.

Common types of lämpöeristeiksi include mineral wool, such as rock wool and glass wool, which are made from spun fibers of molten rock or glass. These materials are non-combustible and have good acoustic properties. Another popular category is foam plastics, including expanded polystyrene (EPS), extruded polystyrene (XPS), and polyurethane foam (PUR/PIR). These offer excellent thermal resistance for their weight and can be rigid or flexible.

Natural materials like cork, wood fiber, and cellulose also serve as lämpöeristeiksi. Cellulose, often derived from recycled paper, is treated for fire and pest resistance. Cork is known for its durability and resistance to moisture.

The effectiveness of a thermal insulator is measured by its thermal conductivity (lambda value), with lower values indicating better insulation. The thickness of the insulating material also plays a crucial role in its overall performance. Proper installation is essential to avoid thermal bridging, which are areas where heat can bypass the insulation, compromising the building's thermal envelope.
