As a high-performance inorganic fiber material, rock wool board has become one of the core materials in the field of modern construction with its excellent fireproof, thermal insulation and sound insulation properties.
Rock wool board is made of basalt as the main raw material and is made by high-temperature melting, fiberization and binder curing. It has the following core advantages:
Fireproof performance: rock wool itself is an A1-level non-combustible material with a fire resistance limit of up to 2 hours. It will not release toxic gases in a fire and is the first choice for building fire isolation zones.
Insulation and heat insulation: The thermal conductivity is as low as 0.033-0.043W/(m·K), which can effectively reduce building energy consumption and is suitable for insulation scenes such as exterior walls and roofs.
Sound insulation and noise reduction: The porous fiber structure can absorb sound wave energy and is widely used in floor sound insulation, industrial equipment noise reduction and other fields.
Environmental protection and health: No volatile harmful substances, excellent hydrophobicity, can prevent moisture penetration and extend service life.
The following are the specific performance indicators of rock wool board:
