External Wall Rock Wool Board

The exterior wall rock wool board is composed of slender and flexible fibers with low slag ball content. It features a low thermal conductivity coefficient, which greatly reduces heat transfer. With outstanding heat and cold insulation performance, it effectively blocks indoor and outdoor heat exchange, delivering excellent and long-lasting thermal insulation effects for buildings.

Made from natural volcanic rock as the raw material, rock wool is a non-combustible building fireproof material that meets the national Class A1 fire protection standard. It will not burn when exposed to high temperature and open fire, and can effectively restrain the spread of fire, significantly improving the overall fire safety of building exteriors.

The rock wool board boasts a water repellency rate up to 99.9% and ultra-low water absorption with no capillary penetration. Even in environments with high relative humidity, its volume moisture absorption rate is less than 0.2%. It can effectively resist moisture and rain erosion, maintaining stable performance in humid and harsh weather conditions.

With slender, tough and high-tensile fibers, the rock wool board offers high compression resistance, excellent tensile strength and long-term durability. It can buffer structural vibration and external pressure, adapt to slight deformation of buildings, and ensure the long-term stability and safe operation of the building exterior wall insulation system.
