State Supply offers foam pipe insulation from Armaflex in 6' lengths and for pipe sizes from 3/8" to 2-1/2". Armaflex insulation features superior condensation control for pipes' outer surface, efficiently reduces heat flow for hot-water plumbing, liquid-heating and dual temperature piping, and dust-free, fiber-free, closed-cell design that prevents moisture from wicking. Armaflex inhibits condensation from water lines, while providing substantial insulation. Armaflex closed-cell sheet insulation works as both an insulator and vapor-retarder by retarding heat gain and controlling condensation drip from chilled water and refrigeration systems. This insulation has a temperature range from -60° to 200°F which makes it ideal for both indoor and outdoor installations. Self-sealing pipe insulation lengths are also available.
