I looking for some guidance on subflooring (osb vs ply). I am building an ICF home on the Bruce Peninsula (we get lots of rain/snow from Great Lakes). I will be waiting on a timberframe roof structure until late Dec. The floors will definitely get their share of weather before being closed in.
I am concerned about the weather exposure…the Norboard osb is alot less expensive, but will it hold up?
The subfloor are spec’d at 3/4″, and will get 1 1/2″ thinset ontop for hydronic heating.
Thanks in advance,
