Mineraalvillit

Mineraalvillit, often translated as mineral wool, is a versatile insulating material produced from molten minerals. The primary raw materials used are rock, slag, or glass, which are melted at high temperatures and then spun or drawn into fine fibers. These fibers are then processed with a binder to create a cohesive mat or batt. The resulting structure traps a significant amount of air within its voids, which is key to its excellent thermal and acoustic insulation properties.

There are two main types of mineral wool: rock wool and glass wool. Rock wool is made from basalt or slag, offering high fire resistance and good acoustic performance. Glass wool, derived from recycled glass and sand, is also an effective thermal insulator and is generally more cost-effective. Both types are non-combustible and contribute to fire safety in buildings.

Mineral wool is widely used in construction for insulating walls, roofs, and floors in both residential and commercial buildings. Its thermal properties help to reduce energy consumption for heating and cooling, while its acoustic characteristics can significantly dampen sound transmission, improving indoor comfort. It is also employed in industrial applications, such as pipe insulation and in the manufacturing of fire-resistant components. The material is generally considered safe to handle when appropriate precautions are taken, and it is often recyclable.
