CCEWOOL® Stone Wool Sound Board is a high-performance stone wool insulation material designed for interior partitions in residential wood and steel stud structures that require exceptional fire resistance and acoustic performance.

This product is non-combustible and, even when directly exposed to flames, will not emit toxic smoke or contribute to fire spread. This critical property provides valuable extra time for evacuation and firefighting operations, ensuring reliable building safety.

CCEWOOL® Stone Wool Sound Board also delivers outstanding acoustic performance. It can be easily integrated with walls, ceilings, and floors to significantly reduce noise transmission, helping create a quieter and healthier indoor environment.

As an ideal solution for enhancing both fire safety and acoustic performance, this product also carries strong environmental attributes, making it a preferred choice for modern residential and commercial buildings.

Easy to cut: Flexible and easy to handle, enabling precise cutting to fit various installation needs.
Non-combustible: High melting point provides superior fire protection for buildings.
Excellent sound absorption: Outstanding acoustic properties effectively reduce noise transmission and optimize indoor acoustic environments.
High-melting fire resistance: Heat-resistant material maintains stability in fire situations, providing additional evacuation time.
Mold- and fungus-resistant: Will not rot or support mold or fungal growth, ensuring a healthy building environment.
Low moisture absorption: Low water uptake resists moisture effects and maintains insulation performance.
Water- and moisture-resistant: Repels water and prevents absorption, ensuring long-term insulation and fire performance.

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.
