Greetings! I'm new to the forum and I'm trying to find help with a question I haven't been able to answer on the net. I'm thinking/wanting to remodel my unfinished attic to make living space out of it. Right now it's insulated on the floor with gable vent and vented soffits. I know that I have to insulate the rafter space with baffles and seeing as though the soffits are vented already I'd like to just put a ridge vent in. However, my rafters are 2x6's and I cant afford to waste head space by increasing the depth. I live in Minnesota, so I know that R-value is a premium here. I read somewhere that 6" of fiberglass insulation is only an R-value of 19? Is that true? And if so, what's my best bet to get a higher R-value without compromising the headroom. I was thinking the blown in closed cell foam insulation, but does anyone have a rough idea what that costs? Also, I read that if I do go with that type of insulation, venting isn't necessary though I can't imagine that to be true. Anyways, as you can see I'm in the beginning stages of this project, but I figure planning the insulation to be the best start. Any help is greatly appreciated!
