Uninsulated Flexible Duct
Uninsulated flexible ducts are lightweight, ribbed aluminum air ducts used in HVAC systems. They consist of a single outer layer without any insulation, making them easy to install in tight spaces. These ducts are best suited for short runs, connections, or areas where thermal insulation and soundproofing are not required.
