Duct Liner

This category features commercial and industrial-grade acoustic and thermal duct liners engineered for internal installation within sheet metal air distribution networks. Designed to absorb low-to-high frequency mechanical fan noise and cross-talk harmonics, these liners provide exceptional acoustic dampening while simultaneously serving as an internal thermal barrier to prevent duct sweating and reduce radiant heat gain or loss. This technical inventory includes high-density fiberglass liners, flexible elastomeric closed-cell foam liners, and eco-friendly cotton-fiber mats. The interior-facing surfaces are manufactured with advanced, high-velocity-rated coatings or glass mats that resist air erosion, prevent fiber migration into the airstream, and feature EPA-registered antimicrobial agents to inhibit mold and biological growth. This professional collection provides mechanical contractors, sheet metal fabricators, and facility engineers with the code-compliant, NFPA 90A/90B and UL 181 tested assets required to optimize indoor air quality (IAQ) and satisfy rigorous acoustic specifications.
