Duct Board Products

At Johns Manville, we believe in providing not just better products, but also better solutions. Our fiber glass duct board offers a high-performance alternative to traditional sheet metal ducts. It provides a number of performance benefits to HVAC contractors, as well as residential and commercial building occupants.

JM duct board dampens unwanted noise and promotes consistent temperatures for less wasted energy. In addition, it contributes to a healthier indoor environment through less air leakage and is protected against damage from microbial growth. Homeowners and occupants will enjoy the benefits of improved comfort, while installing contractors will find JM duct board is easy to fabricate for faster installation. Our duct board solutions offer a wide range of benefits to fit your requirements and needs—because at JM, materials matter.
