CCEWOOL® Stone Wool is primarily manufactured from high-quality natural minerals such as basalt and diabase. After being melted at high temperature, the raw materials are processed through an advanced four-roll centrifugal fiber-forming process to produce discontinuous fibers with a diameter of approximately 4–7 μm. Appropriate amounts of binder, dedusting oil, and water-repellent agent are then added. Through fiber collection, pleating, curing, cutting, and other processing steps, the material is manufactured into Stone Wool products of different densities and specifications.
To meet different insulation structures and installation requirements, the CCEWOOL® Stone Wool range is available in multiple product forms, including Stone Wool Board, Stone Wool Blanket, Stone Wool Blanket with Wire Mesh, and Stone Wool Pipe Section. These products are suitable for building envelopes, industrial equipment, piping, storage tanks, and other thermal insulation, fire protection, and noise-control applications.
What Is the Difference Between Stone Wool for Building and Industrial Applications?
Stone wool can be used in both building and industrial applications, but because the operating environments are different, the product structures and performance priorities also vary.
Stone wool for building applications is mainly used in exterior walls, curtain walls, roofs, partition walls, and other building envelope systems. These applications generally place greater emphasis on fire performance, dimensional stability, tensile strength, water repellency, and sound absorption.
Industrial stone wool is mainly used for equipment, boilers, piping, storage tanks, flue ducts, and air ducts. Greater attention is typically given to thermal insulation performance, adaptability to equipment structures, and the effectiveness of wrapping and fastening.
Therefore, Stone Wool Board is commonly used in building applications, while Stone Wool Blanket, Stone Wool Blanket with Wire Mesh, and Stone Wool Pipe Section are more often used for curved equipment, large-diameter piping, and storage tanks.
What Are the Main Forms of Stone Wool Products?
Depending on equipment structure, installation method, and application requirements, stone wool can be manufactured into a variety of product forms. Common types include Stone Wool Board, Stone Wool Lamella, Stone Wool Blanket, and Stone Wool Pipe Section.
Stone Wool Board
Stone Wool Board is one of the most common forms of stone wool products.
After forming, curing, and cutting to specified dimensions, the product develops a stable board structure with a certain level of mechanical strength, making it suitable for continuous installation over large surface areas.
Typical applications include:
Building exterior walls, curtain walls, roofs, industrial equipment, wall systems, and other flat insulation structures.
When used in external thermal insulation systems for building walls, Stone Wool Board can also be classified into different grades according to tensile strength perpendicular to the surface, based on the applicable standards.
Stone Wool Blanket
Compared with Stone Wool Board, Stone Wool Blanket offers greater flexibility and can adapt more easily to curved and partially irregular equipment surfaces.
Depending on actual operating conditions, it can also be further processed into standard Stone Wool Blanket or Stone Wool Blanket with Wire Mesh.
Main applications include:
Large-diameter piping, storage tanks, boilers, industrial equipment, and other curved surfaces requiring thermal insulation.
Its flexible structure allows it to conform more closely to equipment surfaces and helps reduce excessive cutting and jointing on complex structures.
Stone Wool Blanket with Wire Mesh
Stone Wool Blanket with Wire Mesh is a reinforced stone wool blanket with metal wire mesh added to the surface and secured by stitching.
Compared with standard Stone Wool Blanket, the wire mesh reinforcement improves the overall integrity of the blanket, making it better suited for large industrial equipment, boilers, storage tanks, flue ducts, air ducts, and large-diameter piping where wrapping and secure fixing are required.
Stone Wool Pipe Section
Stone Wool Pipe Section is a prefabricated stone wool insulation product designed specifically for round piping systems.
It can be manufactured in full-round or half-round sections to match different pipe diameters and insulation thicknesses, allowing direct installation around the outside of the pipe.
Main applications include:
Heating pipelines, steam piping, industrial piping, and other systems used to transport hot or cold media.
Compared with wrapping flat products around pipes on site, prefabricated Stone Wool Pipe Sections provide a better fit to the piping structure and can improve installation efficiency.
Main Application Areas of Stone Wool
Thanks to its thermal insulation, fire protection, and sound absorption properties, stone wool is widely used in building envelopes, industrial equipment, piping, storage tanks, and other systems requiring heat control and noise management.
Different product forms can accommodate flat, curved, and cylindrical installation structures.
Building Insulation
In building applications, Stone Wool Board is mainly used for exterior walls, curtain walls, roofs, partition walls, and other building envelope systems.
Its porous fiber structure not only helps reduce heat transfer but can also contribute to fire protection, sound absorption, and noise reduction according to the design requirements of the overall system.
Industrial Equipment Insulation
Stone Wool Board, Stone Wool Blanket, and Stone Wool Blanket with Wire Mesh can be used for the external insulation of boilers, industrial equipment, air ducts, flue ducts, vessels, and other thermal systems, helping reduce heat loss during equipment operation.
Stone Wool Board is better suited for regular and flat structures, while Stone Wool Blanket and Stone Wool Blanket with Wire Mesh can more easily adapt to curved, irregular, and wrap-around equipment surfaces that require secure fixing.
Piping Insulation
Stone Wool Pipe Section and Stone Wool Blanket are widely used for steam piping, heating pipelines, industrial piping systems, and systems that transport hot or cold media.
Prefabricated Stone Wool Pipe Sections can directly match round piping, reducing on-site cutting and jointing. Stone Wool Blanket is more suitable for large-diameter pipes, elbows, and other areas with more complex geometries.
Storage Tank and Large Vessel Insulation
Storage tanks and large vessels generally have continuous curved surfaces, making flexible Stone Wool Blanket or Stone Wool Blanket with Wire Mesh particularly suitable for these applications.
The products can be installed continuously along the equipment surface, helping reduce cutting and jointing in complex curved areas and creating a more continuous insulation layer.
The metal wire mesh reinforcement can also improve the integrity of the blanket during wrapping and fastening.
Fire Protection and Acoustic Applications
Stone wool is an inorganic mineral fiber material and can also be used in building partitions, fire separation systems, equipment noise-control systems, and sound absorption applications.
By adjusting product density, thickness, and structure, stone wool products can meet different system requirements for thermal insulation, fire protection, and acoustic performance.
Stone Wool — An Inorganic Fiber Insulation Material for a Wide Range of Structures
Through different densities, thicknesses, product forms, and surface configurations, stone wool can be applied to building walls, curtain walls, roofs, industrial equipment, piping, storage tanks, fire protection systems, and acoustic applications.
CCEWOOL® Stone Wool is available as Stone Wool Board, Stone Wool Blanket, Stone Wool Blanket with Wire Mesh, and Stone Wool Pipe Section. With customized dimensions and optional surface facings, these products can better adapt to flat, curved, and cylindrical insulation structures.
