Rock wool is an inorganic thermal insulation material made primarily from natural basalt, gabbro, and other minerals. The fibers are melted at high temperatures, drawn into fibers, and then pressed and cut. Due to its stable raw material source and reliable performance, it is widely used in building energy conservation, industrial equipment insulation, and sound insulation systems, and is one of the most common mineral wool materials.

From a properties perspective, the most significant characteristics of rock wool are its strong non-combustibility and excellent high-temperature resistance. The raw ore itself has fire resistance, allowing rock wool to maintain its structure even at high temperatures, making it difficult to burn. Therefore, it is often classified as a Class A non-combustible material. In the construction industry, this characteristic makes rock wool an important safety material in exterior wall insulation, roof insulation, and fireproof partitions.

The fiber structure of rock wool is porous, containing a large amount of air between the fibers, which is why it has excellent thermal insulation performance. The air layer effectively reduces heat transfer, thereby reducing building energy consumption and improving indoor temperature stability. Whether for winter insulation or summer heat insulation, rock wool exhibits stable thermal performance, making it suitable for various building types, including residential, commercial, and industrial buildings.

Besides its insulation function, rock wool also offers sound absorption and noise reduction advantages. Its porous fiber structure absorbs sound wave energy, reducing reverberation and propagation. Therefore, rock wool is a common acoustic material in places with high acoustic requirements, such as computer rooms, cinemas, soundproof walls, and equipment rooms.

Rock Wool Pipes

In the industrial field, rock wool is commonly used for thermal insulation of boilers, heating pipelines, storage tanks, and chemical equipment. Its high-temperature resistance, vibration resistance, and good chemical stability make it adaptable to various complex working conditions. Furthermore, as an inorganic material, rock wool is not easily corroded or prone to mold growth, resulting in a long service life.

However, moisture prevention is crucial during the use of rock wool. Although rock wool itself does not readily absorb water, prolonged exposure to a humid environment may affect its insulation performance. Therefore, it is usually used in conjunction with waterproof layers or aluminum foil to ensure stable performance.

Rock wool felt

In general, rock wool is a mineral fiber material that combines multiple properties such as thermal insulation, sound absorption, non-combustibility, and high-temperature resistance. With its high safety, wide applicability, and stable performance, it has become one of the most commonly used and reliable insulation materials in the construction and industrial fields. In practical applications, suitable rock wool boards, rock wool felts, or rock wool pipe shells can be selected according to the project type and environmental requirements.
