To insulate or not insulate old foundations
Hi, I’m a renovator in Toronto, Ontario and I repeatedly come across the issue of whether or not to insulate non-waterproofed basements. There are many opinions floating around that say to insulate a wet (or potentially wet) basement is subjecting it to damage from freeze/thaw cycles as it will no longer be warmed by the interior. Is this based in science or just fear? I have searched extensively for an answer but can find none. Anybody have some info?
