Adjacent Attic Wall in Catlett, VA

This Catlett, VA homeowner was having issues with their master bedroom being hot in the summer and cold in the winter. Upon an evaluation by Comfenergy, we found one of the walls of the master bedroom were adjacent to the attic above the garage.  The only insulation providing a thermal barrier between this wall and the hot/cold attic on the other side, was falling fiberglass insulation.

Even if fiberglass were in place on this wall it still would not stop air movement and heat transfer through it.  Fiberglass is ONLY effective if it is sandwiched on all sides by an air barrier.

Comfenergy used 2" thick SilverGlo EPS foam boards to build an additional R10 of thermal barrier along the back side of this wall.  More importantly it creates an air barrier for the fiberglass and makes it effective!

Now this customer has a total of R23 on this wall and its air tight!  Comfort at its best!
