DuctSox are cost effective and can be an aesthetically attractive alternative to metal ductwork. DuctSox discharge air through a combination of porous fabrics, engineered orifices and linear vents to meet a large range of HVAC and Refrigeration requirements. LabSox Products are "Fabric" Air Dispersion Devices designed for laboratory environments (Vivariums, Pharmaceutical, Research, etc) UnderFloorSox (UFSoxTM) are designed to provide better air dispersion for underfloor plenums. SkeleCore is a Cylindrical Tensioning Device for fabric ductwork systems. While in the deflated mode, SkeleCore maximizes the duct's open shape and does not deflate allowing for smoother start ups and a better appearance.
