Insulated Flexible Duct

R-Value 1.0 (Polyester Insulation)

Flexible air conditioning ducting, often called ‘flex’, transports heated or cooled air. It moves air from the HVAC unit around the building and back through the grilles or diffusers. Several factors significantly impact each ducting system’s performance. These include the quality of the material, the correct sizing, its R-value, and the installation method.
