Can a cottage built on a concrete piers ever be as warm in Canada as one with a full foundation?
I am trying to minimize the use of concrete in the design of a cottage on flat sandy-ish soil near Huntsville, Ontario. I have heard from contractors that a cottage on piers will always be drafty and that I should go for a full 4 ft insulated concrete perimeter foundation (crawl space).
My question is this – in reality (not theoretically) – can I insulate the floor of a building built on piers enough that it could match the full foundation? What would it take?
Thanks in advance for your help. It is one of those basic questions that no one I have talked to seems willing/able to answer.
