Rock wool board 120kg/m3

Advantages of rigid rock wool:

Excellent fireproof performance:

The raw material of rigid rock wool is natural rock, which is a non-combustible building material with a fireproof grade of A, the highest fireproof grade. It is not easy to burn at high temperature and can effectively prevent the spread of fire. Even in a fire, no toxic gas, smoke or burning droplets or fragments will be produced, and no additional threat will be posed to the safety of personnel's lives, which will buy people precious time to escape.

Excellent thermal insulation performance:

The fiber of rigid rock wool is slender and flexible, and the slag ball content is low, which makes its thermal conductivity low and the thermal insulation effect is excellent. It can effectively block the transfer of indoor and outdoor heat, and can provide good thermal insulation effect for buildings, reduce energy consumption, and save heating and cooling costs, whether in cold winter or hot summer.

Excellent sound insulation and noise reduction performance:

The rigid rock wool is formed by a large number of slender fibers to form a porous connection structure, which makes it an ideal sound insulation material. It can effectively absorb and block the propagation of sound, reduce noise interference, and create a quiet and comfortable indoor environment for people. It is widely used in places with high noise control requirements such as cinemas and KTVs.

Good hydrophobicity:

The hydrophobicity of hydrophobic rock wool products can reach 99.9%, with extremely low water absorption and no capillary penetration. This means that the rigid rock wool can still maintain good performance in a humid environment, and it is not easy to cause the insulation effect to decrease or mold, corrosion and other problems due to water absorption, which increases its service life and stability.

Strong moisture resistance:

The volume moisture absorption rate of the rigid rock wool is less than 0.2% in an environment with high relative humidity; according to relevant standards, the mass moisture absorption rate is less than 0.3%. Even in humid climatic conditions or in a humid environment for a long time, it can maintain good physical properties and thermal insulation performance.

Stable chemical properties:

The rigid rock wool has stable chemical properties, with a pH value of 7-8, neutral or weakly alkaline, and has no corrosive effect on metal materials such as carbon steel, stainless steel, and aluminum. This prevents the rigid rock wool from chemically reacting when it comes into contact with metal components or other materials, ensuring the safety and durability of the building structure.

Safety and environmental protection:

The rigid rock wool has been tested to contain no asbestos, CFC (chlorofluorocarbons), HFC (hydrofluorocarbons), HCFC (hydrochlorofluorocarbons) and other substances that are harmful to the environment. It will not corrode or produce mildew and bacteria. It has been identified as a non-carcinogenic substance by the International Agency for Research on Cancer. Its production process has little impact on the environment, and no harmful substances will be released during use. It is a green and environmentally friendly building material.

Strong and durable:

rigid rock wool has high strength and stability, is not easy to deform, crack or damage, and can maintain good performance for a long time. Under the correct construction and use conditions, rigid rock wool can provide reliable insulation, fire prevention, sound insulation and other functions for buildings, reducing the cost of maintenance and replacement.

Convenient construction:

rigid rock wool is light in weight and easy to carry and install. It can be constructed in a variety of ways such as pasting and keel fixing to adapt to different building structures and construction requirements, which can improve construction efficiency and shorten the construction period
