What are the fire performance of rock wool sandwich panels?

Rock wool sandwich panel is a kind of building material with excellent fireproof performance. It usually consists of two layers of steel plates and a middle layer of gypsum board or rock wool board. Rock wool sandwich panels are widely used in construction projects, especially in large-scale industrial buildings, commercial buildings and public buildings, such as factories, warehouses, supermarkets, gymnasiums, hospitals, etc.

The fire performance of rock wool sandwich panels is mainly reflected in the following aspects:

1. High fire rating

The fire rating of rock wool sandwich panel is usually Class A, which is one of the building materials with the highest fire rating on the market. This is because the middle filler of the rock wool sandwich panel is rock wool, which is an inorganic fiber with good fire resistance. In the event of a fire, rock wool sandwich panels can effectively prevent the spread of fire and ensure the safety of people and property inside the building.

2. High temperature resistance

Rock wool sandwich panels have good high temperature resistance and can withstand high temperatures up to 1000 °C. In the event of a fire, a protective layer of limestone will appear on the surface of the rock wool sandwich panel, which can effectively prevent the spread of fire and ensure the safety of people and property inside the building.

3. Good heat insulation performance

The middle filler of the rock wool sandwich panel is rock wool, which is an excellent thermal insulation material and can effectively isolate heat transfer. Rock wool sandwich panel has good heat insulation performance, which can effectively prevent heat loss inside the building and improve energy utilization efficiency.

4. Good waterproof performance

The surface of the rock wool sandwich panels are covered with coating or galvanized layer, which can effectively prevent the penetration of moisture. Under the erosion of rain or snow, the surface of the rock wool sandwich panel is not easy to be damaged, and it maintains a long service life.

5. Good environmental protection

The middle filler of the rock wool sandwich panel is rock wool, which is a kind of inorganic fiber and has good environmental protection performance. Rock wool sandwich panels do not contain harmful substances, will not pollute the environment, and meet the national environmental protection requirements.

In short, the fireproof performance of rock wool sandwich panel is very outstanding, and it is a kind of building material with excellent performance. The application of rock wool sandwich panels in construction projects can effectively improve the fire protection level and heat insulation performance of buildings, and ensure the safety of people and property inside the buildings.
