MICRO-LOK - Johns Manville Micro-Lok® HP fiber glass pipe insulation is manufactured using the latest technology and our unique in-line manufacturing process. This process results in a uniform fiber glass core that delivers consistent performance during fabrication and installation. In addition, our proprietary auto-jacketer ensures consistency during production and installation resulting in a tighter jacket with a cleaner finished appearance. Micro-Lok HP delivers thermal performance you can count on, while meeting all industry performance requirements. This assures the building owner, mechanical engineer and contractor that Micro-Lok HP will deliver the performance you've come to expect from JM products throughout the life of the mechanical system.
Fiber Glass Pipe Insulation is a high-performance insulation made from rotary glass fibers bonded with a thermosetting resin and produced in 36" (0.92 m) lengths. Micro-Lok HP
insulation is used to insulate standard iron pipe and copper tubing. The 3' (0.92 m) sections are available plain or with a factory-applied vapor-barrier jacket. The all-service (ASJ) vapor-retarder jacket includes a longitudinal, self-sealing closure lap. The jacket system is adhered to each fiber glass section using a specially formulated adhesive to ensure jacket securement. Latex paint may be applied to the Micro-Lok HP
jacket after installation. 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.USES:
fiber glass 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.
