Westlake Pipe & Fittings PVC Cellular Core DWV pipe gives Canadian builders an alternative to ABS for low-rise residential drain, waste and vent systems. It offers better fire performance, quieter drainage and less sag than ABS, and a proven record in cold climates.
- Proven at scale: PVC cellular core is the dominant residential DWV pipe in the U.S., accounting for 76% of the single-family residential DWV market in 2017 and used in every state.
- Built for cold weather: Westlake Pipe & Fittings PVC DWV Cellular Core DWV is manufactured to Canadian-specific ASTM F3128-19, which requires enhanced cold temperature impact testing beyond the older ASTM F891 standard.
- Fire performance: PVC's flame spread index (10–20) is a fraction of ABS's (200–275). It releases less heat and less smoke than the equivalent ABS DWV Pipe.
- Sound performance: PVC cellular core measured quieter than ABS cellular core in CMHC testing.
Westlake Pipe & Fittings PVC DWV Cellular Core Pipe is available in 1½", 2", 3", 4" and 6" sizes. Watch the Westlake Pipe & Fittings video, "PVC Cellular Core: A New Standard for DWV in Canada," to see it in action.
