Sterling Airlite Plenum Boxes offer a lightweight solution for air distribution, they come in the form of pre-assembled units, requiring only one person to install.These plenum boxes generally need no other support, sitting immediately upon the available ceiling grid, thanks to their exceptionally light weight.
We make our Steling airlite plenum boxes from KoolDuct. This is a lightweight pre-insulated ducting system made from CFC free high-density phenolic laminate.
This ducting system replaces the traditional lagged sheet metal systems and has many advantages.
