Hard rock wool board price @News Center Director in charge of telephone fax [Note]: This number is only for customer inquiries, not for promotional activities or sales. Rock wool board is made primarily from high-quality basalt as the main raw material, melted at high temperatures, and processed using the internationally advanced four-roll centrifugal cotton process. The basalt cotton high-temperature solution is drawn into 4~7μm discontinuous fibers, and then a certain amount of binder, dustproof oil, and water-repellent agent are added to the rock wool fibers. These fibers undergo settling, solidification, cutting, and other processes to produce a range of products with varying densities depending on their intended use.

Rock wool board is manufactured using basalt and other natural ores as the primary raw materials, melted into fibers under high temperatures, mixed with an appropriate amount of binders, and processed into a solid state. Widely used in ships, metallurgy, power generation, construction, and other industries, it provides excellent thermal insulation and soundproofing capabilities. Installation is easy and efficient, offering significant energy-saving benefits and a favorable cost-performance ratio.
Marine and hydrophobic rock wool insulation boards include hydrophobic additives during production, providing excellent moisture resistance. Marine rock wool boards are used for ship thermal insulation and fireproof partitions, while hydrophobic rock wool boards are suitable for vehicles, mobile equipment, cold storage projects, air conditioning ducts, and thermal insulation in humid environments or where moisture resistance is needed. Construction-grade rock wool boards offer outstanding fireproofing, thermal insulation, and sound-absorbing properties. They are primarily used for wall and roof insulation in buildings, as well as for fireproofing and noise reduction in building partitions, firewall barriers, fire doors, and elevator shafts. The thermal insulation performance of rock wool insulation boards remains consistently excellent, particularly at normal temperatures, where it outperforms other insulation boards. Additionally, rock wool’s sound insulation capabilities are impressive and are widely utilized in Europe and North America.
When installing rock wool insulation boards, consider the following:
1. Ensure the rock wool board is properly insulated, with pipelines free of leaks. The surface should remain dry, grease-free, and rust-free. In certain conditions, a protective coating may be applied for additional corrosion protection.
2. To minimize heat loss, all joints between the board and felt must be tightly sealed. When using multiple layers of insulation, stagger the cross joints to prevent thermal bridges and maintain cold conditions.
3. For outdoor insulation or areas prone to mechanical wear, such as metal or plastic covers, pay attention to the joints, seams, and seals. Consider adding adhesive seals if necessary, with an overlap of at least 100mm.
4. When applying cold insulation, ensure a moisture barrier is installed on the cold side. At extremely low temperatures, resin-free rock wool should be used, with fireproof moisture barriers.
5. If the rock wool board temperature exceeds 200°C, proper protection is necessary to prevent expansion that could alter the thickness and bulk density.
6. For large-diameter or flat-wall equipment requiring insulation above 200°C, install insulation nails and ensure the outer protective layer is secure.
7. When insulating vertical objects of considerable height, add positioning pins or support rings to the insulation layer, spaced no more than 3 meters apart to prevent slippage due to vibration.
8. Avoid outdoor insulation or cold preservation work on rainy days unless rain protection measures are in place.
Improper handling of rock wool boards can render them ineffective despite installation.
Color Steel Rock Wool Board Sandwich Composite Panel:
This is a new building material featuring colored rock wool board as the outer layer and rock wool, fireproof, and flame-retardant insulation material as the core layer. Its advantages include lightweight, excellent thermal insulation, sound absorption, and sealing capabilities, fast and convenient construction, short project cycles, low comprehensive costs, bending resistance, corrosion resistance, and an attractive appearance.
Characteristics of Rock Wool Board:
(1) Thermal Insulation: Thermal conductivity of 0.035W/m²K.
(2) High Strength: Can function as a retaining and load-bearing structure, with bending and compression resistance. Generally, homes do not require beams and columns.
(3) Bright Colors: No surface decoration required. The color steel plate’s anti-corrosion layer lasts 10-15 years, while the color galvanized sheet’s anti-corrosion layer lasts 30-45 years.
(4) Flexible and Quick Installation: Construction periods can be reduced by over 40%.
It is extensively used in the ceilings, partitions of roofs, walls, and air clean rooms in steel structure workshops and simple portable houses.
