Step 3: Insulate The Perimeter Beam for Energy Savings
Additionally, we recommend insulating the above foundation area, where the floor joist meets the wooden perimeter, with a minimum of an R-10 insulation. This will keep cold air out in the winter, and logically thinking, will create savings on energy costs. In fact, in 2010 Internal Revenue Service was allowing a tax credit percentage for having this done (money saved on the front end). Hopefully, they will continue that program for the future, so consult you tax professional for updates.
