Hi,
I am in the process of converting my attic to living space. I would like to insulate the attic. I have installed the styrofoan baffles but do not know what kind of installation I should use. Could you recommend one, my ceiling joists are 8 inches wide. Also I would like to insulate the side walls they are 2x4's is there insulation for that? One more question, should I install a ridge vent.
Thanks,
Larry

Larry: From you name I guessed where you might live. If I am right the code for your attic is as follows. Attic/ceiling (8" depth) R-38, Exterior walls, R-21. It would probably be best at this point to put in rolled insulation batts. I would recommend a gable vent instead of a roof vent. Why cut a hole in a perfectly good roof.

Jack,
I am also renovating an attic into a living space like Larry. I am not clear on what I need for ventallation. If I use rolled installation do I need a 1" space between the sheathing and the installation? And since I will be drywalling over it all, the two roof vents that I have in now will not access in between all of the joists. Does that mean I need to install a ridge vent?

Hello
Venting is very important if you can install the needed insolation in the roof rafter area with a ridge vent and have room to vent over the top this would be the best thing. But with 8" rafters you will not be able to do that this area becomes unvented, you should install a gable end vent as high as you can on each side and each end to get cross venalation in the unused attic space, in the used attic space (the room) you will need to install a vapor barrier before you install the sheetrock to keep the moisture from getting into the insolation. NOW you should check with your building code in your area to make sure you do every thing right this is a good sized investment let get all you can out of it......
