Rock wool sandwich panel

Rock wool board is an artificial inorganic fiber made by high-temperature melting and processing. It has the characteristics of light weight, small thermal conductivity, heat absorption, and non-combustibility.

Features

Fireproof

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

Main fire protection characteristics:

☉With the highest fire protection level A1, it can effectively prevent the spread of fire.

☉Very dimensionally stable and will not stretch, shrink or deform during fire.

☉High temperature resistance, melting point higher than 1000℃.

☉No smoke or burning droplets/debris produced in fire.

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

heat insulation

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

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-absorbing and noise-reducing material.

Hydrophobicity

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

Moisture resistance

In an environment with high relative humidity, the volume moisture absorption rate of rock wool is less than 0.2%. When tested according to ASMC1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.

Non-corrosive

Rock wool has stable chemical properties, a pH value of 7-8, and is neutral or weakly alkaline. It is resistant to carbon steel, stainless steel,

Metal materials such as aluminum are non-corrosive.

Safety and environmental protection

Rock wool has been tested and does not contain asbestos, CFC, HFC, HCFC and other environmentally harmful substances. Will not be corroded or produce mildew and bacteria. (Rockwool has been recognized as a non-carcinogen by the international cancer research authority)

Key points of construction of rock wool exterior wall insulation system

1. Before construction, a special energy-saving and thermal insulation construction plan for the project should be prepared based on the design and requirements of this regulation and relevant technical standards, and technical explanations and professional technical training should be provided to construction personnel.

2. The construction of the rock wool board external insulation system for energy-saving insulation projects should be carried out in accordance with the reviewed and qualified construction drawing design documents and the approved special energy-saving insulation construction plan for the project.

3. Manufacturers of rock wool board external insulation systems should have professionals to provide on-site guidance during the construction process and cooperate with the construction unit and on-site supervision to control construction quality.

4. Materials entering the site must be inspected and accepted according to specifications, quantity and quality requirements before they can be put into the warehouse. They should be kept by dedicated personnel and stacking in the open is strictly prohibited. Curtain wall rock wool boards should be stacked overhead to prevent moisture.
