Glass Wool Pipe Insulation – Thermal, Flame-Retardant Soundproof for HVAC Systems

Low slag ball content minimizes thermal conductivity, delivering excellent heat retention performance for pipes and ductwork.

Glass wool offers outstanding stability and effectively blocks flame propagation, achieving an A1 combustibility rating.

Based on micro-porous acoustic design principles, sound waves enter the tiny pores and are dissipated as kinetic energy, providing effective noise reduction for piping systems.

Leadsun glass wool pipe insulation is produced using proprietary centrifugal technology and environmentally friendly thermosetting resin binders. Made from ultra-fine glass fibers with diameters of just a few microns, it contains numerous tiny air pockets that provide outstanding thermal insulation, sound absorption, and safety performance. The product can be faced with moisture-proof materials according to customer requirements, making it an ideal solution for pipe insulation in construction and industrial applications.
