First I would like to say hello and that this is my first post on these forums. (Not sure if this is the right Forum) I would like some advise on a room in attic insulation problem. I have a 1 1/2 story home with an unfinished attic built in 1956. Seeing as it tax time and this is our first home we qualify for a $7500 tax credit, which I will be using to finish off. The only thing is, is I am running into problems already and I haven't even started. First thing is first I need to come up with a creative way to vent the attic and I think I have that one figured out. I dont believe that I am going to be able to run a continuous soffit vent so I am going to use the 3 or 4" round popins. Now if I install those I should be alright for venting low, but I am not sure if a gable vent is going to be enough air flow to keep the space Comfterable. So this is where i run into the problem. I only have 2x4 roof joists, now its now problem on the lower part of the roof but about half way to the top I am not sure that this is going to be enough space to insulate without causing a moisture issue. So my question is what do I do, just run the insulation, vapor barrier and the rock over it or should I fur down the joists to make enough room to get some air flow?
