Airlite Plenum Boxes

Sterling Airlite Plenum Boxes are made using KoolDuct® - a lightweight pre-insulated ducting system made from high-density CFC-free phenolic laminate. This ducting system replaces the traditional lagged sheet metal systems and has many advantages. Offering a lightweight solution for air distribution, they come in the form of pre-assembled units, requiring only one person to install. These Airlite plenum boxes generally need no other support, sitting immediately upon the available ceiling grid, thanks to their exceptionally light weight. Combined with their ease of installation, and excellent insulation properties, real savings in both cost and installation time can be expected.
