External walls provide not only a striking appearance for buildings, but also the protection against external influences, such as resistance to UV rays, wind, rain, moisture, noise and temperature variations. More importantly, insulated exterior walls provide a comfortable living environment for people, save energy, and reduce carbon emissions. Rockwell Rockwool is made of natural rocks, such as basalt, and it is a perfect four-in-one product embodying fire safety, sound absorption and noise reduction, durability, and sustainability.

CCEWOOL series of rock wool boards for screen walls are used for fireproof filling of window partitions, window sill walls, and other parts in curtain walls, which provide fire separation for upper and lower floors or units of curtain walls of buildings. They prevent the flame from burning through the window or between layers to the upper or adjacent building units in a fire. At the same time, the filled CWB rock wool has great thermal insulation, sound insulation, and noise reduction.

They can be applied to insulation and fire protection of window walls and window sill walls in curtain wall systems. They protect the force bars in the curtain wall structure that may be exposed to fire.

At the primary stage of building plants, CCEWOOL already began to invest in Italian imported production equipment of international production standards. The rock wool production line has 6 t/h in capacity; surfaces can be overlaid with paper, glass fabric, or aluminum foil. All the raw materials adopt fully automatic batching equipment. Products are produced in accordance with EU EG standards by an advanced four-roller centrifuge to form high-speed centrifugal fiber. Products are then packaged by automatic heat-shrink packaging machines with the use of heat-shrink film that has good penetration resistance and shrinkage. Every step of production has reached the standard of an international top brand in the rock wool field.

CCEWOOL rock wool takes high-quality natural rocks, such as basalt and dolomite, as the main raw materials. The raw materials are melted in the cupola at a high temperature of about 1500 °C and then centrifuged into fibers at a high speed by a four-roll centrifuge. Meanwhile, a small amount of phenol resin with water repellent and emulsified oil is sprayed at the surface of the fabric. Under the action of negative pressure air, the newly formed rock wool fibers are quickly accumulated into felt. Through pendulum, pleating, pressurizing, and curing, the felt is processed into rock wool boards, rock wool felt or rock wool shell, etc. according to the requirement of customers.

CCEWOOL rock wool is free of asbestos and environmentally harmful substances, such as CFCs, HCFCs and HFCs, during the production process; thus, CCEWOOL rock wool does not have detrimental effects on human health, nor does it increase the risk of cancer.

CCEWOOL high-quality rock wool selects top natural rocks as the raw materials, of which Basal, one of the most abundant resources on earth, takes up over 80%.

CCEWOOL rock wool is not only renewable and sustainable, but also is outstanding in energy conservation of industrial cupolas. It is estimated that the use of every m3 of rock wool as insulation material in industrial thermal facilities can save energy up to 2500 kcal/hour, equivalent to three tons of standard coal every year. Also, at least one ton of petroleum can be saved by using one ton of rock wool insulation in buildings.

In addition, its great durability in fire protection and insulation can provide lifelong protection for buildings and for people from noise and fire.
