Rock wool insulation board is mainly used for external walls. Together with the roof, they form the envelope of any building, protecting everyone and everything inside. They also cover the largest surface area, making them a prime area for preventing heat loss. The main place where heat is lost is by escaping through poorly insulated walls.
Key Functionality
With rock wool insulation board, living spaces can be made warm, energy efficient and compliant with modern building standards – as well as gaining additional benefits in terms of acoustics, indoor comfort and fire safety.

Discover the importance of insulation for exterior walls, and the positive impacts it can bring. These boards have many advantages such as light weight, good performance as a whole and low coefficient of heat conductivity. They are widely used in construction and other industries in the heat preservation field.
It also has a good function of sound absorption, so it can be used to reduce industrial noise and deal with the sound absorption in buildings. Rock wool is produced with natural basalt as the main material, melted at high temperatures and made into artificial inorganic fibers by high-speed centrifugal equipment, then added with special agglomerates and dust-proof oil, heated and solidified into various rock wool heat preservation products in different specifications according to different requirements.
