1.Product Overview

Our fiberglass duct board is a rigid, resin-bonded fibrous glass panel engineered exclusively for fabricating rectangular HVAC ductwork. It integrates duct structure, thermal insulation, and sound absorption into a single material, delivering the most cost-effective solution for commercial, residential, and industrial HVAC systems.

Available in 1", 1.5", and 2" thicknesses with R-values ranging from 4.3 to 8.7, our duct boards comply with all major international standards including UL 181, ASTM C612, and CE EN 13162.
