CCEWOOL® Curtain Wall Stone Wool Board is a high-performance semi-rigid stone wool insulation board designed specifically for curtain wall systems, providing exceptional fire protection and thermal performance. Its non-combustible nature ensures that it will not produce smoke or contribute to flame spread when exposed to fire, offering reliable safety for buildings. In addition, this product has moisture-resistant and anti-corrosion properties, maintaining the thermal efficiency of wall assemblies over the long term.

CCEWOOL® Curtain Wall Stone Wool Board is engineered as a high-performance solution for modern curtain wall systems, combining fire resistance, thermal insulation, moisture protection, and durability to deliver enhanced building safety and long-lasting performance.

Low moisture absorption: Effectively discharges moisture from the external wall system and prevents damp accumulation.
Superior thermal protection: Provides higher R-values and long-term stable insulation performance.
Non-combustible: With a melting point of about 2150°F (1177°C), it forms a strong protective barrier in case of fire.
Acoustic performance: Excellent sound absorption, reducing noise transmission and improving indoor comfort.
Chemical inertness: Stable material properties, non-corrosive, and will not affect adjacent structures or components.
Water resistance: Resists water penetration, will not rot, and prevents the growth of mold, fungi, or bacteria, ensuring a healthy building environment.
Reinforced foil facing (optional): Available with reinforced foil surface to increase product strength and application flexibility.

External wall insulation: curtain walls;
Thermal and fire protection for spandrel areas;
Mullion cover panels in curtain wall systems.

At the primary stage of building plants, CCEWOOL already began to invest in Italian imported production equipment of international production standards. The stone 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 stone wool field.

CCEWOOL stone 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 stone wool fibers are quickly accumulated into felt. Through pendulum, pleating, pressurizing, and curing, the felt is processed into stone wool boards, stone wool felt or stone wool shell, etc. according to the requirement of customers.

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

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

CCEWOOL stone 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 stone 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 stone 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.
