Glass wool is made of natural minerals such as quartz sand, dolomite, borax and other inorganic materials, which are mixed according to specific process formula ratio requirements, hot-melted at 1360℃, and made into a series of products such as glass wool felt and glass wool board using advanced centrifugal fiber-forming technology.

The use of fine fibers increases the number of fibers, improves the insulation effect, and compared to 80K rock wool, 16~24KAclear can achieve equal or better insulation performance. It can reduce the weight of insulation materials by 70~80%, achieving significant lightweighting.

The fiber refinement technology improves the sound absorption performance and can improve the sound insulation performance.

No formaldehyde. No materials containing formaldehyde are used in the production process, achieving a comfortable indoor air environment. No odor. Due to the change of adhesive, the peculiar odor of glass wool and rock wool is also eliminated.

It uses basalt, dolomite and other main raw materials, and has extremely strong fireproof and heat-insulating properties.
