Rock wool felt is a flexible, roll-form product consisting of a rock wool mat faced with wire mesh, stainless steel mesh, or fiberglass cloth; it is also referred to as wire-reinforced rock wool felt. It is primarily utilized for the thermal insulation of large-diameter pipelines, storage tanks, large-scale equipment, and irregularly shaped components. The following outlines the characteristics and application scenarios for various types of rock wool felt:
Plain Rock Wool Felt: Suitable for large-diameter pipelines as well as building walls and roofs; it offers excellent thermal insulation properties and sound absorption capabilities.
Fiberglass-Faced Rock Wool Felt: Suitable for large-scale industrial equipment and building structures; it exhibits high tensile strength (resistance to breakage), is easy to install, and-when applied to building walls-provides dust-proofing properties.
Wire-Reinforced Rock Wool Felt: Suitable for environments characterized by high vibration and high temperatures; it is frequently recommended as a thermal insulation material for boilers, ships, valves, and large-diameter, irregularly shaped pipelines.
Wire and Stainless Steel Mesh-Reinforced Felt: Particularly well-suited for the thermal insulation of high-temperature equipment.
These rock wool felt products not only deliver effective thermal insulation but also possess characteristics such as sound absorption, dust resistance, and structural durability, making them widely applicable across various industrial and construction sectors.
