DUCTWORK REDUCES THERMAL DECAYUnderFloorSox from DuctSox is an air-dispersion system designed to reduce thermal decay and improve temperature consistency within the plenum for underfloor-air-distribution systems in retrofit and new-construction commercial buildings. UnderFloorSox are 12- to 18-inch- (305- to 457-mm-) diameter round fabric air ducts routed through a UFAD plenum. No condensation forms on duct surfaces, and the modular design is reconfigurable.
