The Rock Wool Blanket is a high-performance insulation solution designed for industrial systems that demand reliable heat control and energy efficiency. Made from natural basalt rock, it delivers exceptional durability, fire resistance, and acoustic insulation. At Cera Thermal (Jiangsu Cera Thermal Technology Co., Ltd.), we engineer our rock wool insulation to perform under demanding high-temperature conditions across multiple industries. This material helps maintain stable process temperatures, reduce energy loss, and enhance operational safety.
Our Rock Wool Blanket combines excellent thermal efficiency with superior fire and sound insulation. Its fibrous structure traps air effectively, minimizing heat transfer and sound transmission. The non-combustible composition enhances fire safety, making it ideal for both industrial and building insulation projects.
Main advantages include:
High thermal efficiency – maintains temperature stability and minimizes heat loss.
Outstanding fire resistance – non-combustible and suitable for high-temperature environments.
Acoustic insulation – reduces noise and vibration for improved workplace comfort.
Durability and flexibility – retains form and performance under mechanical stress.
Eco-friendly composition – made from natural, recyclable stone materials that meet international standards.
These properties make our stone wool blanket a reliable choice for thermal and acoustic insulation in industrial facilities, power plants, and construction projects.
Cera Thermal offers Rock Wool Blanket options with aluminum foil or galvanized wire mesh facings. The aluminum foil layer enhances moisture resistance and provides a reflective surface for improved heat retention. The wire mesh facing increases mechanical strength, allowing secure installation around curved or irregular surfaces.
Common applications include:
Pipelines and process ducts
Industrial boilers and furnaces
Storage tanks and heat exchangers
Marine and offshore systems
These faced insulation blankets extend service life and ensure consistent performance in petrochemical, power generation, and marine environments.
The Rock Wool Blanket provides dependable thermal protection and energy efficiency for both hot and cold insulation. It supports process stability and reduces operational costs in a wide range of industrial systems.
Typical uses include:
Furnaces, kilns, and boilers
Industrial tanks and reactors
Ducting, piping, and exhaust systems
Power generation and metallurgy
Ceramic and petrochemical plants
In every application, our insulation blanket contributes to energy conservation, safety, and long-term reliability.
