Fiberglass HVAC Duct Board: Complete Turnkey, Ready-to-Install System
We deliver far more than fiberglass HVAC duct boards — a fully integrated duct system from air handlers to terminal diffusers. Every component is precision-engineered for seamless fit, delivering superior airtightness, fire safety and structural integrity.
Our all-in-one package includes AHU flexible connectors, supply air plenums, reinforced duct sections, flanges, hangers, fire dampers, wall sleeves, volume control dampers and grille diffusers. All joints are sealed with fiberglass-specific aluminum foil tape and sealant. Standard suspension brackets are included, with optional waterproofing for outdoor use. This is a true ready-to-install solution: all components arrive pre-matched for immediate on-site assembly, drastically cutting installation time.
