CCEWOOL® External Wall Insulation Stone Wool Board is specially designed and manufactured for external wall thin plaster systems of buildings. It features high vertical tensile strength, excellent dimensional stability, high water repellency, and low water absorption.

CCEWOOL® External Wall Stone Wool Board is mainly used in stone wool external wall thin plaster systems, as well as in non-transparent curtain wall external insulation systems. It can also be applied in external wall insulation systems that use non–Class A insulation materials, serving as fire isolation belts, fire barriers, and similar structures.

Excellent Soundproofing Performance, Creating Comfortable Spaces: The stone wool material offers excellent noise reduction and sound absorption, effectively minimizing noise disturbances to create a quiet and efficient living or working environment.

Superior Breathability, Reducing Moisture Risks: The good breathability of the product helps keep the wall system dry, minimizing potential damage caused by condensation and water accumulation, thus extending the building’s lifespan.

Outstanding Fire Protection, Ensuring Safety: With an impressive melting point of 1177°C (2150°F), the product remains stable in extreme high-temperature environments. It forms a strong fire barrier, effectively delaying the spread of flames and providing reliable protection for buildings, significantly enhancing safety.

Reduced Thermal Bridge Effects, Improving Energy Efficiency: Effectively reduces thermal bridging in wooden structures, significantly enhancing the overall thermal performance of the building envelope, helping to improve energy efficiency and reduce energy consumption.

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 stones, 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 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.
