Top Floor Too Hot/Cold - Catharpin, VA

View Photo Gallery


This Catharpin, VA homeowner was looking for a way to make their top floor cooler in the summer.  There were many issues, but not too many for Comfenergy to handle. Lots of knee-walls and can lights were allowing hot attic air into the house too.


Comfenergy solved the issues with a combination of solutions: spray foam on vertical walls adjacent to living space, covering and sealing can lights, air sealing holes and gaps in the attic, and laying down a nice fresh layer of R60 cellulose insulation.
