Poly B in Newfoundland and Labrador
Everything this library knows about Newfoundland and Labrador: the housing numbers, the code and permit reality, and what genuinely differs on this side of the provincial border.
The 30-second answer
Across the 1 Newfoundland and Labrador cities we profile, roughly 12,314 of 49,255 occupied homes were built in periods overlapping the 1978 to 1998 Poly B installation window. That’s the pool where Poly B lives, not a count of homes that have it, and the only way to answer for a specific home is to look at the pipe.
