What is the right way to to insulate a crawl space?
I have herd so many different ways to insulate a crawl space and I was wondering which one is really the right way.
I have a crawl space that is about 30 inches tall. I have block walls and a dirt floor.
Do you insulate the floor joists or do you insulate the block walls?
If you insulate the joist , do you use foil or paper back insulation?
If you insulate the walls do you use styrofome sheets on the walls or spray?
I have Plastic on the dirt floor.
Does anyone really know the correct way to do this or is this some kind of great mystery?
