External walls provide not only a striking appearance for buildings, but also the protection against external influences, such as resistance to UV rays, wind, rain, moisture, noise and temperature variations. More importantly, insulated exterior walls provide a comfortable living environment for people, save energy, and reduce carbon emissions. Rockwell Rockwool is made of natural rocks, such as basalt, and it is a perfect four-in-one product embodying fire safety, sound absorption and noise reduction, durability, and sustainability.

The thermal insulation rock wool boards for external walls is designed and manufactured for the thermal insulation plastering system of the exterior walls of buildings. It is suitable for dense structures (e.g. concrete foundation walls or brick foundation walls) and exterior walls’ insulation or energy-saving renovation whether it is a new or existing building. This product is ideal for external wall insulation system and also the fire isolation belt along with the external wall insulation system to improve the overall fire safety of buildings. It is great for fire protection, insulation and sound absorption in garage roofs or indoor ceilings.

The thermal insulation rock wool boards for external walls feature high compressive and tensile strengths, low water absorption and hygroscopicity, excellent dimensional stability, and great resistance to thermal expansion or shrinkage and aging. It is compatible with external wall systems and effective in heat preservation, fire protection, and extreme weather protection.

1. High compressive strengths, tensile strengths, and durability indicators, which ensure the stability and reliability of product performances in a long term.

2. The rock wool insulation belt does not burn nor release heat and toxic fumes; it can effectively block flames from spreading during the occurrence of fires because of its outstanding fireproof performance.

3. The thermal insulation performance is superior, which can improve the thermal resistance value of buildings, reduce the energy consumption of heating and air conditioning in buildings, save energy, and reduce emissions.

4. No corrosion occurs on metal materials, such as carbon steel, aluminum (alloy), copper, and various building materials.

5. It possesses physical properties including efficient sound absorption, noise reduction, and elastic vibration damping.

6. Non-hygroscopic, anti-aging, long-term stable performance.

7. Lightweight, can be cut and sawed, easy to construct.

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.
