The core material of CCEWOOL sandwich panels is the best for flat and formed sandwich panels of commercial, industrial and public building designs. It is suitable for indoor and outdoor applications and is widely used in building envelopes, especially in super-span and high-rise buildings. It demonstrates extraordinary advantages in building facades, walls, roofing, partitions, ceilings and high-load sandwich panels.

CCEWOOL Structural Stone Wool core material adopts patented technology and unique formula in production. Stone Wool fiber is specially processed for high quality sandwich panels.

CCEWOOL Structural Stone Wool core material is a product developed for high quality sandwich panels. It involves a comprehensive consideration of various requirements that the composite panel needs to meet in the application of exterior walls, interior walls, firewalls, ceilings, etc., including structural performances, fireproof performances, safety, and durability.

High strength: It has excellent structures and special interface parts which only need to be fixed at both ends. The single span of the panel can reach up to 12 meters;

High fireproof performance: non-combustible structural Stone Wool with a dense node design; up to 4 hours fire endurance, and can block the spread of hot air and flame;

Durable: It can help high-end sandwich panels pass the highest rated durability test of ESSC/CIB.

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.
