Micro-Lok® HP fiberglass pipe insulation is manufactured using the latest technology and our unique inline manufacturing process. This process results in a uniform fiberglass 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.

- Uniform self-sealing lap alignment and adhesion
- Tape is aligned at jacket edge to provide a clean, seamless appearance, tape seals jacket to itself immediately and permanently
- Closure is designed to prevent condensation moisture migration and provide a finished professional appearance
- Release liner functions to protect adhesive from dust when section is being fabricated and installed, release liner is easily removed while wearing gloves
- Consistent jacket adhesion and alignment
- Solid, tight bond between jacket and fiberglass along section length
- Jacket registration is centered on each section to facilitate fabrication
- Smooth fiberglass section surface promotes jacket tightness for optimum finished appearance
- Superior fabrication and cut ability, mandrel wound production for consistent wall thickness and insulation dimension across all pipe sizes
- Allows easy-to-make, clean cuts that accurately fit any pipe size or fitting
- Consistent wall thickness and insulation dimension
- Circumferential jacket scrim lines designed to provide guide for straight cuts
- Clear identification of pipe sizes and Zeston® fitting covers
- Bold-type is easy-to-read in warehouse or jobsite
- Printing is designed to be covered by a butt strip when installation is complete for a clean, finished appearance
- The ASJ jacket has a moisture vapor permeance rating of < 0.02 perms (per ASTM C1136), making it usable in chilled water applications
- Traditional ASJ jacket with a matte paper finish
