The roof is the uppermost layer of the load-bearing and covering components of a house. It must meet the requirements of sturdiness, durability, waterproof, and thermal insulation. It is also light, simple in structure, and convenient in construction. CCEWOOL Stone Wool has excellent fireproof and mechanical properties as well as excellent insulation effects, acoustics, and durability. It enhances the overall performance of the roofing systems in terms of fire protection, thermal insulation, sound absorption, noise reduction, and the durability. CCEWOOL's unique Stone Wool boards for roof insulation is especially ideal for roofing systems because of its light weight, high strengths, and great sound insulation performance.

CCEWOOL Insulation Stone Wool of High-strength Roof are economical products specially developed for the flat roof system. They are mainly used for the bottom layer of the double-layer roofing system. The product has excellent fireproof, thermal insulation, acoustics, and durability properties, and can be used together with other CCEWOOL roofing panels. It can also be applied to the new construction and repair of metal or concrete roofs.

High fireproof standard: A1 fireproof material;

Excellent thermal insulation performance: low thermal conductivity, energy saving for buildings; operating cost reduction;

Excellent acoustic performance, sound insulation, and sound absorption;

Durability: excellent dimensional stability and high water repellency, and the same life as the roof;

Cost-effective: low density, lower system costs.

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.
