I live in Dryden ON and I'm helping a friend of mine renovate his basement, new insulation, VB, drywall etc. I've been reading that as of Jan 2017 R20 is now required for exterior basement walls? Also is 24" centers for the wall studs acceptable or should they be on 16" centers.
Any insight would be a big help.
The insulation is fine. Regarding the studs, we always build with 16" on centers. More stable construction. And as importantly people in the future will expect to find 16" on centers in the wall for thins as simple as mounting a bracket for a T.V. on the wall.
