Its internal fiber structure can absorb and reduce noise transmission.
Soundproofing and Noise Reduction: Its internal fibrous structure effectively absorbs and minimizes noise transmission, enhancing the acoustic performance of both indoor spaces and the surrounding environment. Corrosion Resistance: Glass wool is immune to erosion by chemicals such as acids and alkalis, maintaining stable chemical properties and remaining resistant to aging, deformation, or flaking—ensuring a long service life.

Good thermal insulation performance: Glass wool has a low thermal conductivity, typically ≤0.039–0.042 W/(m·K), effectively minimizing heat transfer, preventing heat loss, and reducing energy consumption. Excellent fire resistance: Glass wool is classified as an A-grade non-combustible material, capable of withstanding high temperatures without igniting when exposed to fire—and it doesn’t release toxic gases, providing reliable protection in fire safety scenarios.

Glass wool insulation pipes are made by adding superfine glass wool to a resin binder, then heating and curing it into a tubular shape. The surface can be coated with protective layers such as aluminum foil, offering features like moisture resistance, radiation protection, and an aesthetically pleasing appearance.
