4" SilverGlo EPS foam boards and one part foam spray are used to "encapsulate" the attic. Notice the attic floor insulation is removed so the heating and cooling can "communicate" with the attic above.
Looking good so far!
This is dirty, nasty, dangerous work people....don;t try this at home!!!
Almost done!
The finished product. Now the top floor of this Broad Run, VA home is nice and cool int he summer, the HVAC runs in a cooler temperature, and they lose almost no heat in the winter!!!
