Natural And Recyclable Rock Wool Boards Widely Applied In Building
Rock wool board is an inorganic thermal insulation material made from natural rocks such as basalt and diabase as the main raw materials, which are melted at high temperature, made into fibration, and then pressed. It is widely used in the construction field due to its excellent performance.
Core Advantages
It mainly undertakes three core functions in buildings: thermal insulation, fire resistance and flame retardancy, as well as noise reduction, while also helping to improve the stability and durability of building structures. Its porous fiber structure can effectively block heat transfer, reduce heat exchange between the inside and outside of the building, help maintain a constant indoor temperature and reduce energy consumption of air conditioning and heating systems. As an inorganic material, it is non-combustible itself, and does not release toxic fumes at high temperatures, which can delay the spread of fire and buy time for personnel evacuation and fire fighting. At the same time, the fiber structure can absorb sound wave vibrations, reduce the transmission of external noise, such as traffic and construction noise, into the room, and reduce the leakage of indoor sound, thus improving the comfort of living or working environments.
Extensive Applications
Rock wool boards have a wide range of applications, covering multiple parts of buildings such as external walls, roofs, and internal partitions. In external wall insulation systems, they are suitable for external and internal insulation of new buildings as well as energy-saving renovations of existing buildings. They can be combined with wall structures such as concrete and brick walls to form a continuous insulation layer, reducing the thermal bridge effect. For roof insulation, they are often used on flat and sloped roofs, capable of resisting the impact of external high and low temperatures on the interior. When combined with waterproof layers, they enhance the integrated waterproof and insulation effect of the roof, making them particularly suitable for buildings with high fire resistance requirements such as factories and warehouses. Indoors, they can be used as filling materials for partitions or insulation layers for ceilings, enhancing the sound insulation performance of walls and reducing noise interference between adjacent spaces. They are widely applied in places with high sound insulation requirements like hospitals, schools, and office buildings.
