Partition walls have evolved from the previous partition-only function to a building component that features fire protection, sound insulation, moisture resistance, and heat preservation. In a wide variety of partition wall systems, light steel keel partitions are widely used because of their light weight and fast construction speed, but their fire performance has always been the main concern. As the best fireproof insulation material, Stone Wool plays an extremely important role in the light steel keel partition walls. CCEWOOL sound- and fire-proof Stone Wool boards are the best choice for the partition systems as they have a high fireproof standard, very good sound absorption, low water absorption, excellent air permeability, and great environmental protection. 

Compared with ordinary Stone Wool boards, CCEWOOL Stone Wool boards of sound insulation and fire prevention have the characteristics of good sound insulation, strong sound absorption, impressive fire resistance, high overall strength, easy construction, and environmental protection. It realizes the perfect combination of five features: sound absorption and noise reduction, fire safety, heat preservation, energy saving, durability and sustainability. It is suitable for sound insulation and sound absorption in hotels, convention centers, office buildings, residential buildings, etc. It can act as the filling of lightweight firewalls to create more comfortable, quiet and private spaces, better sound quality, and higher fire protection for users.

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.
