Features and Advantages

The products have higher strength and better elasticity. The folded rock wol board with certain compression resistance has greater drawing strength, and it does not tend to peel off and has greatly improved durability.


Elastic mid-strength rock wool board: used for heat preservation, fireproofing and sound absorption for the building wall/roof, such as curtain wall, inner wall partition and elevator hoistway, etc.

High-strength rock wool board: used for various high/low temperature conditions, with good weight-bearing ability and compression-resistance, specially suitable for heat preservation and heat insulation for large ships, tanks, ovens,pipelines and other industrial facilities.

Compression-resistant rock wool board: used for roof heat preservation of airport lounge and large workshop as it could bear huge loads.

1. Introduction

Rock wool board

Rock wool is an artificial inorganic fiber made from melted basalt slag wool at high temperature.

It has the characteristics of light weight, small thermal conductivity, good sound absorption performance, non-combustible and good chemical stability.


2. Advantages

Primary advantages of rock wool panel

1)Fire protection: The panel material is non-combustible materials, which can fully meet the requirements of fire protection regulations. The combustion performance depends on how much of the flammable binder is present. Rockwool itself is an inorganic mineral fiber so that not flammable. The using life of the board can reach more than 35 years.

2)Sound insulation performance: Rockwool products have excellent sound insulation and sound absorption. The sound absorption mechanism is the product’s porous structure. When the sound waves pass, friction is generated due to the flow resistance, so that the sound energy is partially absorbs and impedes the transmission of sound waves.

3)Insulation: Rockwool has low thermal conductivity and good thermal insulation. The good thermal insulation performance is the basic characteristics of rock wool and its products. Under normal temperature conditions (about 250C), the thermal conductivity of rock wool is usually between 0.03 and 0.047W/(m·K).


3.Main functions

What is the purpose of the rock wool board?

Marine rock wool board for thermal insulation and fireproofing of ships.

Waterproof rock wool board for vehicles, mobile equipment, cold storage projects, air conditioning ducts.

The rock wool board for construction has excellent fireproof, thermal insulation and sound absorbing properties.


4. Where can rock wool board be used?

Rockwool composite panels are widely used in the ceilings and partitions of steel structure workshops, roofs of simple movable houses, walls, and air clean rooms.

The rock wool panel is suitable for temperature control process, energy conservation and personal protection of equipment and pipelines such as boilers, steam pipes, heat exchangers, reactors, ovens, furnaces, etc., and has good sound absorption, noise reduction and fire prevention.


5. Applications

In modern society, new material rock wool board have been widely used in construction, metallurgy, chemical, electric power, petroleum, agriculture, machinery, light industry, textile, military, transportation, warehousing and other industries. Various buildings, industrial furnaces, boilers, heat exchangers, distillation towers, storage tanks, cold storage flue, pipes, valves, fans, air conditioners, vehicles and ships, as well as the development of modern defense, aerospace, and atomic energy technologies are all this new type of multi-functional material for thermal insulation, sound absorption and noise reduction.
