JM Cancels, Adds Product Lines

DENVER — Due to a recent fire at the Johns Manville (JM) plant in Defiance, Ohio, there is a limited supply of Micro-Lok® Pipe Insulation that has caused JM to end production of preformed, round air duct products. All other JM products for industrial and commercial applications are readily available. The Industrial Insulation Group (IIG), a joint venture owned by Industrial Mineral Holdings (IMH) and JM, also continues to supply industrial insulation without interruption.

JM is accelerating development of a product similar to the Spiracoustic® Plus for metal, round ducts with diameters smaller than 18 inches, to be introduced later this summer. Preformed round products Rigid Round™, Super Round®, and Spiracoustic® will no longer be produced by JM, but will be supplied until existing inventory is depleted.
