Rock Wool Sandwich Panel

 Rock wool is an artificial inorganic fiber made of high-quality natural rocks such as
basalt and gabbro as the main raw material, and is made by
high-temperature melting and fiberization

Rock wool is an artificial inorganic fiber made of high-quality natural rocks such as basalt and gabbro as the main raw material, and is made by high-temperature melting and fiberization. Rock wool sandwich panel consist of two layers of high quality metal sheet (color coated steel plate, galvanized steel plate ) with a high density centre core rock wool. They are highly preferred for their thermal conductivity, low combustibility and high mechanic resistance. Rockwool Sandwich panel has wide applications as roofs, walls, ceilings and are used in the construction of commercial and industrial buildings, Cold rooms and Clean rooms, Refrigerated buildings, Warehouses, Cold storages, Office buildings, Prefabricated containers and cabins, Food processing units, Malls, etc.

Key Advantages

Fire Resistance: grade A1,Non-combustible, which has improved the overall fireproof performance of steel buildings.
Fast Construction: it is fast  and flexible to install on the construction site. The construction period can be shortened by more than 40%.
Excellent performance in thermal insulation and sound absorption: Through testing, the sound insulation effect of a sandwich panel with a density of 120kg/ m³ rockwool as the core material can reach RW=29-30dB
Both sides of the tongue and groove are filled with polyurethane foam, which can effectively prevent heat conduction and rain leakage and improve the overall strength
High acidity coefficient, reducing corrosion to metals
