Dekoron Unitherm invented pre-insulated pipe and tubing in 1962 and introduced their next-generation 6200-BPE system. The 6200-BPE offers major advantages over field fabrication like lower installed costs through reduced waste and labor. It uses aerogel insulation, white PVC jacketing, and molded covers for fittings to provide a maintenance-free, impact resistant insulated piping system.
