The Hartfords retrofit
DFI completed a basement insulation retrofit at the Hartfords house in Peru. After removing the R11 fiberglass in the rim joist area, we could see why the basement was cold.
There was quite a few holes that you could see outside in the area, add that to the concrete block foundation and you have alot of air leakage. We then applied 2" R14 closed cell foam in the rim joist and too the concrete foundation to seal up all those holes and cracks allowing the cold air to filter in. The Hartfords wont have to worry about any pipes freezing down there this winter or any winter to come. Read more. www.energycircle.com/blog/2012/02/05/helping-hartfords-and-finding-path-...
