Composite Rock Wool Board

Composite Rock Wool Board is a high-performance integrated insulation and fireproof material independently developed and produced by Hebei Huashuo Xingye Thermal Insulation Building Materials Co., Ltd. Based on high-quality basalt rock wool as the core insulation core material, it is compounded with different functional surface layers (color steel plate, cement mortar, aluminum foil, PVC film, etc.) through advanced processes such as high-temperature bonding, hot pressing and coating. The product perfectly integrates the excellent fire resistance, thermal insulation and sound absorption of rock wool with the structural strength, waterproofness and decorative performance of the surface layer materials, making up for the defects of single rock wool board in mechanical strength and environmental adaptability. It has the characteristics of light weight, high integral rigidity, simple construction and multi-scenario adaptation, and is a core material widely used in industrial and civil construction, industrial insulation, marine engineering and other fields, realizing the integrated effects of insulation, fireproof, waterproof, sound insulation and structural protection.

Core Product Characteristics

Integrated High Performance & Multi-Function Integration

The product takes A-class non-combustible rock wool as the core, inheriting the characteristics of high temperature resistance (up to 800℃), extremely low thermal conductivity (0.04~0.055W/m·K) and excellent sound absorption and noise reduction. Combined with the functional advantages of different surface layers, it realizes the integration of multiple properties: color steel surface layer enhances structural strength and corrosion resistance; cement mortar surface layer improves compression resistance and construction adaptability; aluminum foil surface layer has super thermal reflection and moisture resistance; PVC film surface layer adds decorative performance and easy cleaning property. It meets the diversified functional requirements of different application scenarios with one material.

Super High Structural Rigidity & Mechanical Strength

Through the professional composite process, the rock wool core material and the surface layer are firmly bonded without delamination or falling off, which greatly improves the integral rigidity, bending resistance and impact resistance of the board compared with the ordinary rock wool board. The product can bear external pressure, wind load and structural vibration for a long time without deformation and damage, and even can be used as the enclosure and load-bearing structure of simple buildings without additional beam and column support, with high bearing capacity and stable structural performance.

Enhanced Environmental Adaptability & Durability

The composite surface layer forms a dense protective barrier for the rock wool core material, effectively isolating the erosion of water, water vapor, acid and alkali gas and ultraviolet rays. The product has ultra-high hydrophobic rate (≥98.0%), extremely low water absorption and good chemical stability, which can maintain stable performance in harsh environments such as coastal high-salt spray areas, southern rainy areas and industrial high-humidity workshops. The corrosion resistance of the surface layer (such as color steel plate anti-corrosion layer service life up to 10-15 years, aluminum-zinc plated plate up to 30-45 years) is excellent, and the service life is far longer than that of the single rock wool board.

Excellent Fire Safety & No Toxic Emission

The whole board reaches the national A-class non-combustible fire protection standard, and the rock wool core material will not burn, melt or produce toxic smoke and combustible droplets in case of fire, effectively blocking the spread of fire and heat transfer. The composite surface layer materials are all environmentally friendly fireproof materials, which will not decompose and release harmful substances at high temperatures, and the organic content of the whole board is strictly controlled at an ultra-low level, fully meeting the fire safety requirements of high-rise buildings, public facilities and industrial plants.

Green Environmental Protection & Healthy Application

The product takes natural basalt and other inorganic minerals as the main raw materials, without adding formaldehyde and other harmful additives in the production and composite process, and no toxic and harmful gases are released during construction and long-term use, complying with the national green building and indoor environmental quality standards. The production process has low energy consumption and low emissions, and the waste materials can be recycled and reused, in line with the low-carbon environmental protection development concept; at the same time, the product has low moisture absorption, is not easy to get damp and moldy, and can maintain the cleanliness of the application environment.

Simplified Construction & High Efficiency

The composite rock wool board is pre-processed in the factory to form an integrated structure, which directly omits the on-site processes such as plastering and surface treatment required for the construction of ordinary rock wool boards, and the construction period can be shortened by 40%~70%. The product can be installed by mechanical fixing, splicing and bonding, and the modular splicing structure (with plug, notch and mortise and tenon design) can realize quick clamping with installation efficiency improved by 60%. It is suitable for rapid construction of large-scale projects and has good compatibility with various building materials.

Main Product Types & Matching Characteristics

According to the different surface layer materials and structural design, the product is divided into several classic types to meet the personalized needs of different scenarios:

Color Steel Composite Rock Wool Board

With color coated steel plate as the surface layer and rock wool as the core, it is formed by hot pressing with adhesive. It has the characteristics of bright color, no need for additional decoration, high strength and corrosion resistance, and is suitable for the roof and wall of steel structure factories, prefabricated movable rooms and clean rooms.

Cement Mortar Composite Rock Wool Board

The surface of the rock wool board is coated with cement mortar to form a firm plaster layer. It has the advantages of excellent fire performance, high compression resistance and low cost, and is the ideal material for the external wall external insulation system of high-rise buildings, hospitals, schools and other public buildings with strict fire requirements.

Aluminum Foil Faced Composite Rock Wool Board

One or both sides of the rock wool core material are covered with aluminum foil or aluminum foil composite glass fiber cloth. It has super thermal reflection performance and moisture resistance, can effectively prevent the rock wool from absorbing moisture and failing in insulation, and is widely used in the insulation of cold storage, refrigerated trucks and ventilation pipelines in low-temperature environments.

PVC Film Faced Composite Rock Wool Board

The decorative layer of polyvinyl chloride film is pasted on the galvanized steel plate or directly compounded on the rock wool core material. It has strong decorative performance (can simulate wood grain, stone grain and other textures), smooth surface and easy cleaning, and is suitable for indoor partition walls, suspended ceilings and office separation with decorative requirements.
