Duct Board, Wrap, and Liners

This category features commercial and industrial-grade duct boards, thermal wraps, and acoustic duct liners engineered to optimize thermal resistance and deliver targeted sound attenuation within high-velocity air distribution networks. Designed for application on sheet metal ductwork or for the fabrication of self-supporting duct systems, this technical inventory includes high-density fiberglass duct boards with durable, reinforced foil-scrim-kraft (FSK) vapor barriers, exterior thermal blankets (duct wrap), and interior acoustic liners. These materials maintain precise conditioned air temperatures by establishing a high-efficiency thermal boundary ($R$-value) that reduces HVAC plant load and eliminates structural condensation or "duct sweating." Additionally, the interior liners are specifically engineered with advanced water-repellent, antimicrobial coatings that resist air erosion at high velocities while absorbing mechanical fan harmonics. This professional collection provides mechanical contractors, sheet metal fabricators, and facility engineers with the code-compliant, NFPA 90A/90B tested assets required to maximize thermal performance and enhance indoor air quality (IAQ).
