Rock wool, also known as mineral wool, is a high-performance thermal insulation and fireproof material made from natural volcanic rock (mainly basalt) and dolomite. With its excellent comprehensive properties, it is widely used in construction, petrochemical, electric power and other industries worldwide.

Rock wool products are made from high-quality molten basalt as the primary raw material. Through the four-roller centrifugal fiberizing process, the molten basalt is drawn into discontinuous fibers with a diameter of 4–7μm.Subsequently, a precise amount of binder, dust suppressant, and water repellent are added to the fibers. The mixture then undergoes a series of procedures including sedimentation, lamination, curing, and cutting, before being fabricated into products of varying densities and forms—such as blankets, boards, and pipes—tailored to specific application requirements.Additionally, the products can be supplied either as plain (non-faced) versions or with a wire mesh facing. This versatile material is widely used for thermal insulation in construction, petroleum, electric power, and chemical industry equipment, as well as for insulation in building partitions, curtain walls, roofs, and overall building envelope systems.

Excellent thermal insulation performance, outstanding structural stability and long service life.

Fire-resistant & Flame-retardant.

Made of flame-retardant materials, it is non-combustible and safe for application.

The product's long-fiber structure features good elasticity, which can effectively reduce vibration, achieving remarkable shock absorption, sound insulation and noise reduction effects.

1.Soft and lightweight, easy to cut and install — ideal for wrapping irregular components.
2.Low thermal conductivity delivers exceptional insulation, paired with excellent sound absorption performance.
3.Class A non-combustible for superior fire resistance, plus strong chemical stability and an extended service life.

Product Feature

A standout advantage of Heat Resistant Acoustic Wall Rock Wool Insulation is its exceptional high-temperature resistance. 
This makes it the ideal material for fire-prone areas such as industrial buildings, commercial kitchens, and boiler rooms. 
Capable of withstanding temperatures up to 1000°C, it delivers reliable performance even in extreme high-heat environments.
 
Beyond heat resistance, this rock wool insulation also boasts superior acoustic dampening properties. It effectively absorbs sound waves and reduces ambient noise, making it a top choice for noise-sensitive spaces like recording studios, theaters, and conference rooms.
 
Durability is another key benefit. Resistant to moisture, mold, and mildew, the insulation maintains its integrity over time without deterioration. It is thus a long-lasting, cost-effective solution for all insulation needs.
 
For optimal performance, proper fitting and airtight sealing during installation are essential. This ensures the material fulfills its designed insulation and soundproofing potential to the fullest.
