As a fibrous material, Uetersen rock wool is used in the field of building insulation, with thermal insulation, sound absorption and noise reduction, high mechanical strength and fire resistance. The above properties are achieved by the air chamber formed by the interweaving of the rock wool fibers through the adhesive. Therefore, the first and most important quality evaluation is the quality of rock wool fiber. The quality of the fiber determines the quality of rock wool.

　　Fire protection is required for both exterior and interior walls. When selecting an exterior wall insulation material, two factors should be considered: how the material will react to fire and how the material will resist fire. Almost all types of rock wool insulation are classified as non-combustible to provide longer protection.

　　Uetersen rock wool has strong high temperature resistance, and is different from traditional thermal insulation materials, with A1-level non-combustible properties, so the fire-resistant wrapping core material used in the direction of smoke prevention and exhaust can be used in conjunction with fire-resistant boards to achieve 3 hours of fire resistance fire resistance. The melting temperature is over 1100°C, which can protect the building for a longer time.

　　Uetersen has made adjustments in raw materials and formulations to improve the durability of rock wool, and will not cause stress corrosion and copper-aluminum-iron corrosion to austenitic stainless steel. The unique fire performance can be used as a fireproof material and a structural protective layer, which can delay or completely prevent the summer movement of the fire. Low thermal conductivity ensures good energy-saving properties, preserving its excellent thermal insulation properties throughout the life of the building.

　　In addition to the direction of fire-resistance, fire-resistance, and heat-insulation, Uetersen rock wool is also often used in the direction of renovation of old houses and wall insulation. The thermal insulation material has various choices for the wall base, that is, it can be used in the new plastering layer and can be used for wrapping the wall of the old house. It has the effect of roof renovation and insulation. It integrates the functions of heat preservation, sound insulation, protection and energy saving. The real energy saving benefits achieved are much higher than the estimated potential energy saving benefits.
