PVC Ductwork KCH Services Inc. Forest City NC

KCH Services has received Factory Mutual approval for its polyvinyl chlo- ride (PVC) ductwork as a feasible al- ternative to fiberglass reinforced plas- tic (FRP) ductwork. As a result, the need for fire sprinklers in PVC duct- work is nonexistent. The new KCH unplasticized PVC duct does not bum readily. It softens and melts under the heat of the fire, causing the PVC duct to collapse onto itself, starving the fire. The PVC is an inert, homogenous ma- terial extruded into uniform sheets and/or various shapes that can be formed, cut, machined, heat welded, or solvent welded with no change in physical or corrosion-resistant proper- ties.
