CCEWOOL® Stone Wool Board HD is an economical product specially developed for flat roof systems, primarily used as the bottom layer in double-layer roof systems. It offers excellent fire resistance, thermal insulation, acoustic performance, and durability. When combined with other CCEWOOL® roof board products, it can be applied to both metal and concrete substrates for new construction and renovation projects.

To cater to different application needs, CCEWOOL® Stone Wool Board HD can be coated with fiberglass or asphalt, further enhancing its functionality and durability. The product not only excels in soundproofing, fire resistance, and durability but also significantly enhances the energy efficiency of buildings.

Additionally, CCEWOOL® Stone Wool Board HD features excellent fire resistance, dimensional stability, good breathability, and is mold-resistant, making it highly suitable for fire doors and other OEM applications that require rigid board insulation.

High fire rating: Classified as A1 non-combustible material.
Excellent thermal insulation: Low thermal conductivity reduces building energy consumption and lowers operating costs.
Superior acoustic performance: Provides outstanding sound insulation and absorption.
Durable performance: Excellent dimensional stability and high water repellency, ensuring service life equivalent to that of the roof.
Cost-effective: Lower density helps reduce overall system costs.

Roof insulation 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.
