This Leesburg, VA homeowner was having trouble keeping their top floor cool in the summer. So, they called Comfenergy to solve the problem!
The existing fiberglass insulation was allowing air to travel through and around it, thus radiating heat through the drywall behind it, and making the top floor hot.
Closed cell spray foam insulation was used to air seal and properly insulate this vertical wall.
The HVAC register "boots" were encapsulated with spray foam to keep them from sweating when the cold metal would hit the hot 130 degree attic air.
Comfenergy installed plywood "dams" around the attic hatch to keep the new insulation from falling whenever opened.
New insulation depth sticks were installed to ensure the proper depth for the homeowner.
Here is the finished product. The top floor is now cool and comfortable for the homeowner.
