CCEWOOL® Stone Wool Board 55/65 is a medium-density rock wool insulation material designed for external and internal non-load-bearing steel-faced firewalls, offering excellent fire resistance, thermal insulation, and durability. This product provides at least 1 hour of fire protection, ensuring the fire safety of buildings.

Specifically, CCEWOOL® Stone Wool Board 65 offers 1-hour fire protection, while CCEWOOL® Stone Wool Board 55 provides a 2-hour fire rating (measured from the interior side). Both products meet stringent fire safety requirements and provide builders with flexible design options that allow for reduced spacing between buildings, thereby increasing usable building area.

CCEWOOL® Stone Wool Board 55/65 is the ideal solution for modern construction's fire and thermal insulation needs, offering builders efficient and reliable design options that enhance fire safety and energy performance.

Exceptional Fire Protection, Enhancing Safety: Made from non-combustible materials, it will not burn, produce toxic smoke, or contribute to the spread of fire, providing a reliable fire barrier for the building.

Outstanding Acoustic Performance, Optimizing Environmental Experience: With excellent sound absorption capabilities, it effectively reduces noise transmission, creating quiet and comfortable work and living environments, improving productivity and quality of life.

Efficient Waterproofing, Protecting Structural Integrity: The material does not absorb moisture and allows vapor to pass freely, preventing moisture buildup and reducing potential damage to the building structure.

Long-Lasting Durability, Stable Performance: The material retains its stable performance over time, resisting mold and corrosion, providing ongoing, reliable protection for the building, and ensuring long service life.

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.
