This Sterling, VA homeowner was looking to lower their utility bills.
The existing fluffy, fiberglass insulation was uneven, and it allows a tremendous amount of "wind washing" to pass through it. Very inefficient at holding air in or keeping air out.
Once the insulation had been removed it was time to air seal all air gaps and leaks with one part spray foam.
Finally, TruSoft cellulose was installed to a level of R60. Now this house will be nice and comfortable and the HVAC system will run less.
