house was built in the early 20's. Still original plaster in most of the house. windows are single pane, double hung, with good wall coverage. roof is relatively new, attic (house is a 4 square) has a finished room in a large portion (unclimatized), but has access hatches to the remainder of the attic which is plywood over joists for storage. There are roof vents on 3 of the 4 sides of the roof. In the attic space, there is older r-?(13 at MOST) in the joist cavities, with the facing to the bedroom sides. Along the walls of the attic room is r-13 unfaced in the studs and along the roof deck there is r13 in the bays faced into the attic space. at the lowest part of the roof, (but not yet to the soffit) there is some kind of blown in white substance (possibly vermiculilte, but I think this was done recently), but I dont think this goes all the way into the soffit. The soffit is NOT vented at all. The upper part of the roof (above the finihed room) is not ventilated, accessible, or insulated (I had to remove some drywall to fix a ceiling light) but is probably not fully broken from the lower roof other than by the r-13 bats in the roof deck.
Ok - now that that is out of the way.!
Our upstairs is very uncomforatble this time of year. Our master bedroom especially. It is in the southeast corner of the house and will be 5-10 degrees warmer than other rooms in our upstairs, including the mirror image room adjoining it (northeast) with the same windows open.
Obviously a lot of the conversation with this would need to be hand by someone onsite as a lot of this is hard to describe, but what am I missing that this is so hot? The other big issue is that the upstairs seems to be holding in the heat quite a bit more than I would suspect it should. For example, it was 85 in our bedroom last night, and when we woke up it was only down to 83 despite being in the low 70's last night and with all the windows open and the ceiling fan running the whole time.
I've had mixed responses regarding the insulation of the attic room, should the access hatches be open or sealed, should the atttic be soffit vented, should the roof even be vented (FYI, I suspect the roof was redone about 3 years ago, and thats when the r-13 was placed on the deck. They had covered the roof vents, although I suspect that was the previous home owner - unless there was a reason to cover them....). Should the deck be insulated or should we pull up as much of the floor as we can and fit as much insulation into the bays as possible (the joists are not very deep).
We are actually going to switch bedrooms to one I percieve to be cooler because this is getting so obnoxious.
Sorry for the long winded post.
Ok - that
