Rock Wool Fireproof Panel

Rock wool fireproof panel is a new type of fireproof building material, which is widely used in mobile board room, paint baking room and electronic clean room. As a new type of sandwich panel, rock wool sandwich panel has the characteristics of good fire resistance, heat preservation and heat insulation performance.

Fire rating of rock wool panel

1. Class A: Non-combustible building materials: materials that hardly burn.

2. Grade B1: Flame retardant building materials: The flame retardant materials have a good flame retardant effect. It is difficult to catch fire in the air or under the action of high temperature, and it is not easy to spread quickly, and the combustion stops immediately when the fire source is removed.

3. Grade B2: Combustible building materials: Combustible materials have a certain flame retardant effect. When exposed to open fire in the air or under the action of high temperature, it will immediately catch fire, which may easily lead to the spread of fire, such as wooden pillars, wooden roof trusses, wooden beams, wooden stairs, etc.

4. Grade B3: Flammable building materials: without any flame retardant effect, it is very easy to burn and has a great fire hazard.

External wall insulation materials are classified according to fire rating:

a. Insulation materials with Class A combustion performance: rock wool, glass wool, foam glass, foam ceramics, foamed cement, closed-cell perlite, etc.

b. Insulation materials with combustion performance of B1 level: specially treated extruded polystyrene board (XPS) / specially treated polyurethane (PU), phenolic, rubber powder polystyrene particles, etc.

c. Insulation materials with combustion performance of B2 level: molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

What are the characteristics of rock wool sandwich panels?

1. Fireproof

The raw material of the outer wall rock wool board is natural volcanic rock, so it will not burn easily, and it is a fireproof building material.

2. Thermal insulation

The fiber of the outer rock wool board is slender and flexible, with low slag ball content and small thermal conductivity, so it has excellent thermal insulation performance.

3. Sound absorption and noise reduction

Rock wool is a kind of sound insulation material with excellent performance, and its interior is a porous structure formed by many slender fibers.

4. Non-corrosive

The chemical properties of rock wool are stable, normally neutral or weakly alkaline, and will not be corroded when used with carbon steel, stainless steel, metal and other materials.
