Micro-lok HP fiberglass pipe insulation is a high-performance insulation made from rotary glass fibers bonded with a thermosetting resin and produced in 36 inch (0.92 m) lengths. Micro-lok HP insulation is used to insulate standard iron pipe and copper tubing. The 3' (0.92 m) sections have an all-service (ASJ) vapor-retarder jacket with a longitudinal, self-sealing closure lap. The factory-installed tape system permits installation at ambient temperatures down to 20°f (-7°c) and will not soften or separate when exposed to high ambient temperatures and humidity. Micro-lok HP fiberglass pipe insulation is suitable for installation over hot, cold, concealed and exposed piping systems with operating temperatures up to 850°f (454°c). weather-protective jacketing is required for outdoor applications. Pipes operating below ambient temperatures require all joints to be sealed with the factory-applied, Self-Seal lap and butt strips.
