Basalt Rock Wool Board

Basalt Rock Wool Board is a high-grade thermal insulation and fireproof material independently produced by Hebei Huashuo Xingye Thermal Insulation Building Materials Co., Ltd., taking high-quality basalt as the core raw material. It is manufactured through the advanced process of high-temperature melting of basalt ore, high-speed centrifugal spinning to form continuous fibers, professional curing and precision cutting. Based on the superior physical and chemical properties of basalt itself, the product has more excellent high-temperature resistance, structural strength and durability than ordinary rock wool boards, and retains all the classic advantages of rock wool materials. It is a premium choice for high-end building engineering, industrial high-temperature insulation and key fire protection projects with strict performance requirements.

Core Product Characteristics

Superior High-Temperature Resistance & Fire Safety

Taking basalt with high melting point as the raw material, the product is an inherent non-combustible material, which can withstand high temperatures above 600℃ and has an ultra-high hot load shrinkage temperature. In fire conditions, it will not melt, burn or release toxic smoke and combustible gases, and can stably block the spread of fire and heat transfer for a long time, providing a more reliable fire protection barrier for buildings and industrial equipment. Its organic content is strictly controlled at an ultra-low level, and there is no combustion-supporting component in the material, which fully meets the national and industrial top-level fireproof material standards.

Excellent Mechanical Strength & Structural Stability

Basalt fibers have higher toughness and strength than ordinary rock fibers. The board has uniform fiber distribution and strictly controlled slag ball content (the proportion of particles with diameter greater than 0.25mm). It has outstanding compressive strength and tensile strength, can withstand long-term heavy pressure, structural vibration and external impact without deformation, cracking or falling off, and is suitable for complex application scenarios such as high-rise building external walls, heavy industrial equipment insulation and large-scale steel structure fire protection.

Outstanding Thermal Insulation & Energy-Saving Performance

The product has an extremely low thermal conductivity, and its density is customizable in the range of 80-180kg/m³ (special specifications available), with conventional thickness of 30-150mm. The dense and uniform fiber structure can effectively block heat conduction and convection, and the thermal insulation performance is more stable and durable than ordinary rock wool boards. It can significantly reduce building energy consumption and industrial equipment heat loss, achieve excellent energy-saving and emission-reduction effects, and is suitable for energy-saving insulation projects of high-end commercial buildings, industrial kilns and precision equipment.

Strong Chemical Stability & Corrosion Resistance

Basalt raw material has excellent chemical inertness, making the board have super resistance to acid, alkali, salt and various corrosive gases. It will not produce chemical reactions and performance attenuation in harsh environments such as chemical workshops, metallurgical plants and outdoor humid and corrosive areas, and can maintain stable physical and chemical properties for a long time. Its acidity coefficient is much higher than the industry standard, which is the ideal insulation material for chemical, metallurgical, electric power and other heavy industrial fields.

Superior Water and Moisture Resistance & Durability

It has a high hydrophobic rate and extremely low volume water absorption. The special basalt fiber structure is not easy to absorb water and mildew, and can keep excellent thermal insulation and mechanical properties even in humid environments such as building roofs, basements and industrial pipeline trenches. It effectively avoids performance degradation caused by water absorption, and the service life is far longer than ordinary rock wool boards, reducing the later maintenance and replacement costs of the project.

Eco-friendly & Healthy & Low-Carbon

The product is made of natural basalt ore without adding any harmful additives, and realizes zero formaldehyde release in the whole production and use process, without emitting toxic and harmful gases, complying with the highest standard of green building materials. The production process has low energy consumption and low emissions, and the waste materials can be recycled and reused, in line with the development concept of low-carbon environmental protection. At the same time, it has good moisture resistance, which can maintain the cleanliness of the indoor and industrial environment and protect the health of users.

Multi-functional Integrated Advantages

While having the above core performance, it retains the porous structure of rock wool materials, with excellent sound absorption and noise reduction performance, which can effectively absorb industrial mechanical noise, building environmental noise and pipeline vibration noise, and optimize the acoustic environment of the application site. It also has good air permeability, which can promote air circulation, reduce the risk of condensation water formation, protect the building structure and industrial equipment from moisture damage, and realize the integrated effects of fireproof, thermal insulation, sound absorption, moisture proof and corrosion resistance.

Main Application Scenarios

High-End Building Engineering

Widely used in the external wall insulation, curtain wall fire protection, fire isolation belt and roof insulation system of high-rise residential buildings, luxury commercial complexes, five-star hotels, high-end office buildings and landmark buildings, providing high-performance and long-life thermal insulation and fire protection solutions for high-end buildings.

Heavy Industrial Field

It is the core insulation and fireproof material for industrial kilns, boilers, high-temperature ovens, smelting equipment in metallurgy, chemical industry, electric power, steel and other heavy industrial fields, as well as high-temperature pipelines and large storage tanks, resisting high-temperature baking and corrosive medium erosion, and ensuring the safe and stable operation of industrial equipment.

Key Fire Protection Projects

Applied to the fire protection and insulation of key public facilities with high fire safety requirements such as stadiums, transportation hubs (airports, high-speed railway stations), hospitals, data centers and nuclear power auxiliary facilities, as well as fire partition walls and fire isolation belts of flammable and explosive industrial plants, providing reliable fire protection guarantee for key projects.

Steel Structure Engineering

Used for the fireproof protection and thermal insulation of large steel structure buildings such as industrial plants, large-span stadiums and steel structure bridges. The high-strength basalt rock wool board can be closely combined with the steel structure, forming a firm fireproof protective layer, effectively improving the fire resistance limit of the steel structure.

Quality Control & Product Specifications

Strict Quality Detection

The product strictly abides by national and industrial rock wool product standards, and carries out more stringent detection on all core quality indicators based on the characteristics of basalt rock wool, including organic content, slag ball content, fiber diameter, hydrophobic rate, compressive strength, tensile strength, thermal conductivity, acidity coefficient and hot load shrinkage temperature. The detection methods cover combustion method, screening test, electron microscope detection, chemical titration, high-temperature furnace test, etc., ensuring that all performance indicators reach the premium level of rock wool products.

Customizable Product Specifications

The conventional density range is 80-180kg/m³, the thickness is 30-150mm (special thickness can be customized), the width is 1200-2400mm, and the length is 600-1200mm. It can be customized into special specifications according to the actual needs of different projects, and can be matched with a full range of basalt rock wool products such as basalt rock wool strips, rock wool felt and fire barriers to form a complete thermal insulation and fire protection system.
