We purchased a century home a year ago and discovered over the winter that our kitchen floor gets extremely cold. We've been reading up on how to insulate, but I am unsure which part of the Ontario building code applies. We have a fill basement made of stone and to the back, where the kitchen is we have a small window that leads to a crawl space with the same walls but no foundation floor (best guess is that this used to be a summer kitchen). In any case, I'm wondering what the is the best way to insulate.
2 lb sprayfoam is the best and only proper way to do an existing century-old home like that. It can be done from underneath without upsetting your finished floor in the kitchen area and 2 lb has built-in vapour barrier. This is the most expensive way but proper and easiest way you will not regret it call a local trusted Pro contractor in your area to get a spray foam quote
2 part spray foam is best.
You may benefit from spraying foundation wall only. Not the floor, and blown in some of your warm basement sir.
The cold comes from the surrounding frozen earth against your foundation walls, which makes the crawl space cold.
Insulating the foundation wall will stop the cold.
Blowing in warm basement air will keep the crawl space dry and warmer, solving the cold floor.
