Stone Wool Blanket | Flexible Thermal Insulation for Industrial Equipment & Piping | CCEWOOL®

CCEWOOL® Stone Wool Blanket is manufactured primarily from natural basalt through high-temperature melting, fiberization, and a flexible forming process. It is a flexible inorganic fiber insulation material that combines thermal insulation, fire resistance, and sound absorption.

With a temperature rating of up to 750°C (1382°F), its flexible blanket structure can conform closely to large-diameter pipes, storage tanks, equipment shells, and irregular surfaces, helping maintain a continuous insulation layer while reducing cutting and jointing around complex structures.

For industrial equipment and piping projects, insulation materials need not only to reduce heat loss, but also to accommodate curved surfaces, corners, vibration, and outdoor operating conditions. CCEWOOL® Stone Wool Blanket provides a flexible insulation solution for these complex installation requirements.

750°C Temperature Rating for Industrial Insulation Applications

CCEWOOL® Stone Wool Blanket is available with a temperature rating of:
750°C (1382°F)

The product can be used for boilers, vessels, industrial equipment, large-diameter pipes, storage tanks, flue gas ducts, and other industrial areas requiring continuous thermal insulation, providing flexible configuration options for different operating conditions.

Flexible Blanket Structure for Complex Equipment Surfaces

Compared with rigid boards, CCEWOOL® Stone Wool Blanket provides greater flexibility and conformability.

The blanket can closely fit:
Large-diameter pipes
Cylindrical storage tanks
Curved equipment shells
Irregular equipment surfaces
Valves and localized complex structures
Flue gas ducts and large industrial ducts

Its flexible structure helps reduce large gaps that may occur when rigid boards are installed on curved surfaces, creating a more continuous insulation layer while reducing on-site cutting and adjustment.

For large industrial equipment and piping systems, the blanket structure is also well suited to large-area wrapping and installation.

Stable Thermal Insulation Helps Reduce System Heat Loss

CCEWOOL® Stone Wool Blanket consists of a dense network of fine inorganic fibers, creating numerous air pockets within the fiber structure that help reduce heat transfer.

Its stable fiber structure and thermal performance make it suitable for long-term industrial insulation, helping reduce heat loss from equipment, piping, and storage tanks and thereby minimizing unnecessary energy loss.

For continuously operating systems in power plants, chemical plants, and other industrial facilities, a stable insulation layer also helps maintain long-term thermal efficiency.

A1 Non-Combustible Performance for Thermal and Fire Protection

CCEWOOL® Stone Wool Blanket is primarily made from inorganic mineral fibers and can meet A1 non-combustible requirements.

Under high-temperature or fire conditions, the stone wool itself does not burn or produce flaming droplets, allowing the material to provide both thermal insulation and fire protection.

In addition to conventional equipment insulation, Stone Wool Blanket is also suitable for applications with higher fire-safety requirements, including:
Power plant equipment
Chemical processing equipment
Large storage tanks
Industrial piping
Building walls and roofs
Fire separation systems

For projects requiring both heat-loss control and fire protection, Stone Wool Blanket can provide these functions within one insulation system.

Porous Fiber Structure for Sound Absorption and Noise Reduction

The porous fiber structure of Stone Wool Blanket not only limits heat transfer but can also absorb part of the sound energy generated by equipment and airflow.

For boilers, piping near fans, flue gas systems, industrial facilities, and equipment enclosures where operational noise is present, CCEWOOL® Stone Wool Blanket can provide thermal insulation while also helping reduce noise transmission.

For industrial systems exposed to both elevated temperatures and equipment noise, this combination of thermal insulation and sound absorption provides additional application flexibility.

Multiple Facing Options for Moisture Protection and Mechanical Support

CCEWOOL® Stone Wool Blanket can be supplied with different facing materials according to project requirements.

For example:

Aluminum Foil Facing
Helps improve surface moisture resistance and overall system integrity;

Wire Mesh Facing
Provides additional support and structural stability for large equipment surfaces, vertical installations, and applications subject to vibration.

Different facing options can be selected according to equipment structure, environmental conditions, and installation methods, allowing Stone Wool Blanket to integrate more effectively into complete industrial insulation systems.

Typical Applications of Stone Wool Blanket

CCEWOOL® Stone Wool Blanket is particularly suitable for projects requiring flexible wrapping, continuous insulation, and installation on complex surfaces.

More Than Flexible Insulation for Complex Industrial Structures

The core advantage of CCEWOOL® Stone Wool Blanket goes beyond flexibility.

By combining a flexible blanket structure, stable thermal insulation, A1 fire performance, sound absorption, and optional aluminum foil or wire mesh facings, the product can adapt to a wide range of complex building and industrial insulation environments.

Compared with rigid boards, Stone Wool Blanket is better suited to continuous wrapping around large-diameter pipes, storage tanks, curved equipment, and irregular surfaces. Compared with conventional flexible insulation materials, its inorganic mineral fiber structure also provides a combination of fire resistance, thermal insulation, and long-term stability.

For projects requiring thermal insulation, fire protection, sound absorption, close conformity to complex structures, and reliable long-term industrial performance, CCEWOOL® Stone Wool Blanket provides a mature and flexible insulation solution with broad engineering adaptability.
