Rock wool board, also known as rock wool insulation decorative board, is an inorganic fiber board made primarily from basalt as raw material through high-temperature melting and processing. It is a new type of material for thermal insulation, fire resistance, and sound absorption.
Curtain wall special rock wool board serves as a fireproof sealing material in curtain wall structures. It is mainly used for fire and smoke blocking and sealing gaps between curtain walls and structural floors or partition walls, as well as in hard-to-see areas within the system, thereby forming a fire barrier. By dividing the building into independent fire compartments, it prevents the spread of fire within the building during a fire, achieving passive fire protection. This rock wool board is also suitable for filling and sealing gaps where fire and smoke commonly penetrate, such as those between fire dampers and their building installation structures.
Additionally, curtain wall special rock wool board can be used to fill gaps between wall-penetrating pipes or other wall-penetrating devices and firewalls or fireproof floors. The product is easy to use and particularly suitable for filling irregularly shaped gaps caused by wall-penetrating objects. It is also employed for thermal insulation in curtain wall system window wall panels to reduce heat loss in these areas. The excellent fire resistance of the rock wool board enables the formation of fire compartments between the building's window sill walls and edge reinforcement systems, effectively enhancing the overall fire performance of the building.
Apart from thermal insulation, rock wool boards also provide soundproofing and noise reduction. The sound absorption effect of rock wool depends not only on its thickness but also on its density and whether the surface has sound-absorbing perforations. For soundproof walls, materials with different properties must be combined. For example, soundproofing materials can be added in front of load-bearing brick walls. To meet fireproof requirements, a 100 mm thick rock wool layer, enclosed and decorated with flexible fabrics, can achieve the desired performance.
