What is the best way to insulate the exterior of an old house?
We live in central Alberta, Canada. Our house has R-12 insulation in the walls with vapor barrier.
I would like to add some sort of insulation on the outside and put on new siding. I would like some suggestions on what type of foam product is best, etc.
