Marc insulating the ceiling in the living/dining room. Messy itchy stuff. Horrible. I got to be an expert in cutting it though. Marc did virtually all of the stapling. It took way more than we expected. Marc also sound proofed every interior wall with insulation. You can see the Reflectix material between the rafters and the roof - it's kinda like aluminum foil with insulation sandwiched between. It bounces the heat from the sun back off the roof. We also have it on the west wall of the house. We blew in cellulose insulation in the attic areas above the porches. Those areas are completely enclosed. Since they house the A/C ductwork we wanted them to be well insulated.
