INSUL-TUBE® is used to prevent heat gain and prevent condensation or frost formation on refrigerant lines, cold water plumbing, and chilled water systems. It also retards heat flow for hot water plumbing, liquid heating, dual temperature piping, and many solar systems. Designed for the HVAC and Refrigeration industry. INSUL-TUBE® is non-porous, non-fibrous and resists mold growth. An EPA registered antimicrobial agent is incorporated into the product providing additional protection against mold, fungal and bacterial growth. INSUL-TUBE® Pipe Insulation is made from a UV resistant elastomeric blend. For moderate UV exposure, no additional protective coating is needed. However, for severe UV exposure (rooftop applications) or where optimum performance is required, 374 Protective Coating or approved jacketing or cladding should be used.
