System XFR vs Cast Iron Test English
Contractors installing DWV pipe in high buildings and plenums had few alternatives to heavy cast iron and copper. IPEX has changed that. System XFR — the world’s first PVC DWV system rated for high buildings and air plenums where tighter Flame Spread and Smoke Development requirements of the Building Code have previously limited the use of thermoplastic.
Suitable for use in noncombustible environments, System XFR’s advanced material meets all fire-resistance and smoke development codes. Its revolutionary fire-retardant properties eliminate flame spread and reduce the volume of smoke generated.
And in addition to its reliable smoke and fire protection, System XFR delivers all the performance advantages you’d expect from thermoplastic piping.
