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.
