Rock Wool Board

Rock Wool Board

Rock wool board is mainly divided into the following types:

1. Ordinary rock wool board: mainly used for building insulation, heat preservation, sound absorption, etc.

2. High-density rock wool board: has higher strength and better heat insulation performance, suitable for industrial insulation with high requirements.

3. Fireproof rock wool board: added with fire retardant, has good fire resistance, suitable for places with strict fire protection requirements.

4. Colored rock wool board: the surface is specially treated and has a variety of colors. In addition to the heat preservation and heat insulation function, it also has a decorative effect.

5. Moisture-proof rock wool board: after special treatment, it has certain moisture-proof performance and is suitable for humid environments.

6. Waterproof rock wool board: the surface is waterproofed and has good waterproof performance, suitable for occasions where waterproofing is required.

7. Steel structure rock wool board: specially designed for steel structure buildings, with good adhesion and compressive strength.

8. Veneer rock wool board: the surface is affixed with aluminum foil, paper and other materials, which is both beautiful and has certain decorative and protective effects.

Rock wool composite board is a composite board with rock wool as the core material and metal or other materials covered on the outer layer. It has good heat insulation, sound insulation and fireproof performance, and is widely used in building exterior walls, roofs, partitions and other parts. The structural design of the rock wool composite board makes it lightweight while having high strength and stability. It is one of the commonly used energy-saving materials in modern buildings.

Composite mortar ester rock wool board is a new type of building energy-saving material, which consists of a rock wool core material and a composite mortar layer on both sides. This board has good thermal insulation performance, and also has certain fireproof and sound insulation effects. It is suitable for the external insulation system of the building exterior wall, which can effectively improve the energy efficiency of the building and reduce energy consumption. In terms of construction, the composite mortar ester rock wool board is easy to install and compatible with a variety of building materials. It is an ideal choice for modern green buildings.

Rock wool board, also known as rock wool insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. The test was successful in June 1981. Rock wool board is a new type of thermal insulation, flame retardant and sound absorption material.

Rock wool board is an artificial inorganic fiber processed by high-temperature melting. It has the characteristics of light weight, low thermal conductivity, heat absorption and non-combustibility. It was initially developed as a common application type in construction and is mostly used in industrial buildings. It should comply with the provisions of "Application Types and Basic Requirements of Building Insulation Materials".

7 characteristics of rock wool board

1. Fireproof

The raw material of the exterior wall rock wool board is natural volcanic rock, which is a non-combustible building material fireproof material.
Main fireproof properties:

● It has the highest fireproof grade A1, which can effectively prevent the spread of fire.

● The size is very stable and will not stretch, shrink or deform in a fire.

● High temperature resistant, with a melting point above 1000℃.

● No smoke or burning droplets/fragments will be produced in a fire.

● No harmful substances and gases will be released in a fire.

2. Thermal insulation

The fibers of the exterior wall rock wool board are slender and flexible, and the slag ball content is low. Therefore, the thermal conductivity is low and it has excellent thermal insulation effect.

3. Sound absorption and noise reduction

Rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that Shikeda rock wool is an excellent sound absorption and noise reduction material.

4. Hydrophobicity

The hydrophobicity of hydrophobic rock wool products can reach 99.9%; the water absorption rate is extremely low, and there is no capillary penetration.

5. Moisture resistance

In an environment with high relative humidity, the volume moisture absorption rate of rock wool is less than 0.2%. According to the ASTMC1104 or ASTM1104M method test, the mass moisture absorption rate is less than 0.3%.

6. Non-corrosive

Rock wool has stable chemical properties, a pH value of 7-8, and is neutral or weakly alkaline. It has no corrosion to metal materials such as carbon steel, stainless steel, and aluminum.

7. Safety and environmental protection

Rock wool has been tested to contain no asbestos, CFC, HFC, HCFC and other environmentally harmful substances. It will not be corroded or produce mildew and bacteria. (Rock wool has been recognized as a non-carcinogenic substance by the International Cancer Research Authority).
