If my crawlspace is ventilated, can I still insulate the walls of the crawlspace, or is it better
to insulate the floor?
If you have a vented crawlspace with pipes and uninsulated ducts, it is better to insulate the crawlspace
walls. If there are insulated ducts and no pipes, the best course of action is to insulate the floor above.
The vents should be closed in the winter and open in the summer.
