Contractors installing DWV pipe in high-buildings and plenums had few alternatives to heavy cast iron and copper. IPEX® has changed that. System XFR® is the world's first PVC DWV system rated for high-buildings and air plenums where the national building code mandates more stringent flame spread and smoke development requirements which previously limited the use of thermoplastic. Suitable for use in non-combustible environments, system XFR® advanced material has a flame spread rating of 25 and smoke developed classification of 50 which permits it to be installed in high-buildings and air return plenums in accordance with local codes. In addition to its flame and smoke attributes, system XFR® delivers all the performance advantages you'd expect from thermoplastic piping.
