DuctSox Fabric Duct and Diffuser Systems have many advantages and benefits, many of which are green and can be helpful in attaining LEED credits. Because the entire DuctSox System is a diffuser, air can be supplied to the occupied space in a more effi-cient pattern. DuctSox Systems may be designed with fittings similar to metal ductwork, including many standard zippered fittings and unlimited customization to match any application requirements. The cost of a DuctSox System is 20 to 80% less than metal. The cost savings of air porous DuctSox are even more dramatic when compared to insulated/double-wall spiral metal duct or premium materials. There is also considerable savings in the labor time required to install DuctSox versus a comparable metal system. Our fabrics are available in a variety of standard colors and patterns, including custom colors to match any interi-or decor. DuctSox can personalize your DuctSox System—advertise your company or school logos, mascots, inspirational sayings, sponsors, or suppliers.
