I am a widow, trying to do a major remodel. I am trying to educate myself as I go, and although it's slow-going, I have finally completed the framing and electrical, plumbing, and HVAC rough-in. I have installed new energy efficient doors and windows, added new Hardie siding to the exterior, and put on a new metal roof. I am now ready for insulation and sheetrock, but am having a hard time figuring how I should insulate the attic. I have perforated exterior soffit in place, and a ridge vent the length of the roof. Spray foam insulation under the roof decking is not an option. The house is a very simple straight-run ranch type design, 66' x 26'. The roof pitch is not steep. I have put a thermal barrier product called Polaralum under the metal roof. Now I am trying to decide what kind of insulation to put in the attic. In particular, I'm wondering if it would make any sense to put batts in between the roof rafters, and to also put batts in between the ceiling joists. Just wondering if this would enhance the insulating properties of the attic and help to minimize the heat/cold transfer to the conditioned space below. I like the idea of batts between the ceiling joists because then I could still see the 2x4's. (Could I then put a plywood 'floor' over the batts on top of the joists?) The attic is not tall enough to stand up in, so I'm not thinking of it as any kind of 'living space,' but possibly for some additional storage. (I had to put my HVAC system in the attic, as it was really the only option.) One suggestion I've had was to put 5 1/2" of blown-in insulation above the ceiling, which I guess is pretty standard, but what happens if you ever need to find the wiring, plumbing, bathroom exhaust fans, can lights, etc. in the attic? Any help or recommendations would be greatly appreciated.
