Rock Wool Board

Rock wool board is a high-performance thermal insulation and fireproof building material produced by Hebei Huashuo Xingye Thermal Insulation Building Materials Co., Ltd. It is made from molten rock minerals through centrifugal spinning, curing and cutting processes, with excellent comprehensive performance and a wide range of applications in construction, industry and other fields.

Core Performance Characteristics

Fire Safety

It is a non-combustible material that can withstand high temperatures up to 600℃, effectively preventing the spread of fire and not producing toxic smoke at high temperatures. Its high hot load shrinkage temperature ensures stable performance in high-temperature environments, providing valuable evacuation time in fire accidents and reducing thermal damage.

Thermal Insulation

With an extremely low thermal conductivity, it can effectively block heat transfer, maintain the stability of indoor and industrial equipment temperatures, reduce building energy consumption and industrial heat loss, and achieve excellent energy-saving and emission-reduction effects. Its density ranges from 80-180kg/m³ (customizable for special specifications), and the thermal insulation performance is positively correlated with the density within a reasonable range.

Sound Absorption and Noise Reduction

The porous internal structure enables it to effectively absorb sound waves, reduce the spread of mechanical equipment noise and environmental noise, improve the acoustic environment of spaces such as theaters, recording studios, classrooms and conference rooms, and is also widely used for noise reduction in industrial pipelines and building partition walls.

Durability and Stability

It has high compressive and tensile strength, can withstand long-term pressure without deformation, and is suitable for various building structures, especially the external wall insulation system of high-rise buildings. It also has good chemical stability, resistance to acid and alkali corrosion, and stable performance in various harsh environments, ensuring long service life. The acidity coefficient of the board is an important index to measure its acid resistance, determining its application scope in chemical, metallurgical and other fields.

Waterproof and Moisture-Proof

It has high hydrophobic rate and extremely low volume water absorption. Even in humid environments, it can maintain good thermal insulation and sound insulation performance, reduce the risk of condensation water formation, protect the building structure from moisture damage, and is especially suitable for external wall and roof insulation systems.

Breathability and Environmental Protection

It features good air permeability, which can promote air circulation, adjust indoor humidity and improve the comfort of living and working environments. As an environment-friendly material, it has low organic content (strictly controlled by combustion or chemical analysis), no formaldehyde release in the formaldehyde-free type, non-toxic and harmless to the human body. The production process has low emissions, and the product can be recycled, in line with the concept of low-carbon energy conservation.

Key Quality Detection Indicators

The quality of rock wool board is strictly controlled through a series of professional detection items, including organic content, shot content (the proportion of particles with a diameter greater than 0.25mm), fiber diameter (detected by microscope, laser particle size analyzer, etc.), hydrophobic rate, volume water absorption, compressive strength, tensile strength, raw material calorific value, raw material sulfur content, density, thermal conductivity, acidity coefficient and hot load shrinkage temperature. All indicators comply with national and industrial quality standards to ensure the stable performance of the product.

Main Application Fields

Construction Field

It is widely used in building curtain walls, wall partitions, steel structure fire protection and insulation, prefabricated interior insulation filling, roof insulation systems, etc. It can improve the fire safety level of buildings, reduce energy consumption, and achieve the effects of sound insulation and moisture proof. It is suitable for residential buildings, commercial buildings, industrial plants and various public facilities.

Industrial Field

It is an ideal thermal insulation and fireproof material for industrial kilns, boilers, ovens, industrial pipelines, large storage tanks (including chemical storage tanks, petroleum storage and transportation tanks, LNG storage tanks), ventilation pipelines (especially commercial kitchen exhaust pipelines) and industrial equipment. It can reduce heat energy loss, maintain the temperature stability of conveying media and stored substances, and protect industrial equipment from high and low temperature damage.

Product Specifications

The conventional thickness of rock wool board is 30-150mm (special specifications can be customized), the width is 1200-2400mm, and the length is 600-1200mm. It can be matched with other rock wool products such as rock wool felt, rock wool strip and fire barrier belt to form a complete thermal insulation and fireproof system, meeting the diverse application needs of different scenarios.
