High-temperature Resistant Rock Wool Board

Rock wool board, also called rock wool thermal insulation and decorative board, is mainly made of natural basalt with other inorganic mineral raw materials. It is a new inorganic fiber board integrating thermal insulation, fire prevention, sound absorption and noise reduction, produced by high-temperature melting (up to 1400℃), fiberization, molding, pressing and solidification. As a high-quality inorganic thermal insulation material, it is widely used in industrial fields for its environmental protection, durability and stable performance, becoming a core material for modern construction and industrial thermal insulation and fire prevention.

Rock wool board has four prominent core advantages in practical use:

First, thermal insulation. Its dense porous fiber structure blocks heat conduction, keeping indoor heat in winter and isolating outdoor high temperature in summer, reducing energy consumption and improving comfort.

Second, fire resistance. As an inorganic material, it is Class A non-combustible, producing no toxic fumes when burning, slowing fire spread and providing time for evacuation and property protection.

Third, sound absorption. Its porous structure absorbs sound waves and reduces reflection, effectively lowering environmental noise to create a quiet space.

Fourth, uniform thickness. Precision molding ensures small thickness error and high flatness, facilitating construction and ensuring project quality stability.

With excellent performance, rock wool board is widely used in many industrial fields, mainly including:

Marine industry (ship cabin insulation, fire and sound proofing); metallurgical industry (equipment and plant insulation); power industry (boiler and pipeline insulation and fire prevention);

Construction industry (building wall, roof insulation, fire walls and partitions); chemical industry (equipment and pipeline insulation, auxiliary anti-corrosion);

Other scenarios: industrial plants (overall insulation, fire and noise reduction), cinemas (noise reduction), and ceiling projects (insulation, fire and sound absorption), meeting diverse needs.

A special rock wool board is designed for flexible waterproof roof systems, retaining basic functions while optimizing performance for roof use.

It has good compressive strength (bearing personnel and equipment weight without deformation), water repellency (low moisture absorption, stable in humid environments), and moisture resistance.

It also has excellent thermal stability (no obvious thermal expansion/contraction), dimensional stability, chemical stability, aging and weather resistance, resisting natural erosion and having a long service life.

It is suitable for both new building roof projects and existing building roof renovation, meeting construction requirements and maintaining stable performance for long-term safety guarantee.
