External Duct Insulation

At Johns Manville, we’re committed to the details that matter to you. We offer a range of fiber glass duct wrap solutions that provide traditional sheet metal ducts with improved thermal insulation. Our duct wrap is available in a variety of densities, thicknesses and with or without facings.

In addition, JM Microlite® EQ is now manufactured with a bio-based binder made primarily of rapidly renewable, plant-based materials, which satisfies the industry’s growing demand for agriculturally sourced products. Installing contractors prefer it for many reasons, including improved handling, easier cutting and less dust. Residential and commercial building occupants appreciate the consistent temperatures and improved comfort and energy efficiency that JM fiber glass duct wrap provides.
