A recent fire at a Johns Manville (JM) plant has limited supply of the company’s Micro-Lok[R] Pipe Insulation and caused JM to end production of pre-formed round air duct products.

A recent fire at a Johns Manville (JM) plant in Defiance, Ohio, has limited supply of the company’s Micro-Lok[R] Pipe Insulation and caused JM to end production of pre-formed round air duct products. All other JM products for industrial and commercial applications are readily available.

The company is distributing Micro-Flex[R] Pipe and Tank Wrap, a semi-rigid fiber glass blanket with a random fiber orientation that allows the material to wrap pipes and equipment without gaps, as a suitable substitute for Micro-Lok in many applications. Micro-Flex will be stocked at JM’s Cleburne, Texas, plant so it can be shipped in mixed loads.

Other products unaffected by the fire include Zeston[R] and Ceel-Co[R] PVC fitting covers and jacketing, and Spin-Glas[R] equipment and board insulations.
