1. Product Overview
With excellent thermal insulation, fire resistance, sound absorption, and corrosion resistance properties, rock wool board is widely used in building energy efficiency, industrial equipment insulation, petrochemical, metallurgy, power generation, shipbuilding, transportation, and other fields.
As a representative product of modern high-temperature insulation materials, rock wool board not only provides excellent thermal physical properties but also meets strict environmental protection standards. It is an ideal choice for high-temperature insulation, energy consumption reduction, and improved safety protection.
2. Core Product Features
■ Excellent Fire Resistance
Rock wool board is a non-combustible material (Class A1). It can withstand high temperatures in fire conditions, prevent the spread of fire, and protect buildings and equipment safety.
■ Excellent Thermal Insulation Performance
With low thermal conductivity (0.034-0.045 W/m·K), rock wool board maintains stable thermal resistance under high-temperature conditions and effectively reduces energy loss.
■ Good Mechanical Strength
It features high compressive strength and good toughness, is not easy to break during installation and transportation, and is convenient for cutting and installation.
■ Sound Absorption and Noise Reduction
The fiber structure can absorb sound waves, reduce industrial noise and indoor echo, and improve environmental comfort.
■ Moisture Resistance and Corrosion Resistance
Some rock wool boards can be covered with films, aluminum foil, or polymer waterproof layers to improve moisture resistance and adapt to various complex environments.
■ Environmentally Friendly and Non-Toxic
Free of asbestos, compliant with RoHS and REACH environmental standards, safe for humans and the environment without harmful emissions.

11. FAQ
Q1: What is the difference between rock wool board and glass wool board?
A1: Rock wool board is made from natural minerals such as basalt and diabase. It has better fire resistance, higher compressive strength, and is suitable for high-temperature industrial applications and building fire protection requirements. Glass wool board is mainly used for indoor thermal insulation and sound absorption, with relatively lower temperature resistance.
Q2: Can rock wool board be used outdoors?
A2: Yes. However, it is recommended to choose rock wool board with waterproof film or aluminum foil facing to improve moisture resistance and extend service life.
Q3: Is rock wool board environmentally friendly?
A3: Yes. Rock wool board is asbestos-free, has no carcinogenic risk, and complies with RoHS and REACH environmental standards, making it safe for use.
Q4: Is rock wool board difficult to install?
A4: No. Installation is simple. It can be cut according to requirements and supports mechanical fixing or adhesive installation. Proper protective measures should be taken during construction.
Q5: Can the thickness and density of rock wool board be customized?
A5: Yes. We provide customized solutions for different thicknesses, densities, and surface treatments with composite materials according to customer requirements.
