Best way to insulate room over garage?

we have a fan we run , but when it gets 85 degrees or hotter in the summer , the water droplets appear toward the middle of the afternoon when its the hottest . Is there too much insulation above it . there is a attic above it . we had a new roof and siding put on a month pior to this happening. thanks

Hi, I bought a house built in 1948 which is missing insulation in large areas. I have been posting on here for a while trying to figure out what kind of home I own and found out that "1.5 story homes" are a pretty common thing here. To me I just look at it as if someone converted an attic to obtain more living space. Anyways, there are 3 tiny bedrooms upstairs that average about 100-150 square feet. I would like to know how to insulate the rooms properly. I don't want to spend money by insulating areas that aren't necessary or where there is little to gain. I also don't want to go with blow in insulation at this time because the drywall in this home likes to crack. I know that I must obviously insulate the outside wall and that is just fine with me. However, I am somewhat confused beyond that. I have placed a drawing below illustrating my understanding of where I believe that I should insulate and the areas where I have no idea on earth as to whether or not I should insulate. As for the [B]blue[/B] airbrushed areas below: I am confident that this is where I need to insulate. After this I am completely lost. Once I crack the kneewalls open, I can get to the areas in [B]red[/B]. Do I insulate those areas? What about the areas in [B]Green[/B]? I can reach those pretty easy. The areas in [B]brown[/B] are the few inches between the kneewalls and the very top area (top triangle). I can not see being able to insulate this area unless some rigid pieces of insulation were put there and I would guess that area needs to breathe? The areas in [B]purple[/B] are difficult to reach as well because that would require popping the drywall open in the ceiling, going through existing insulation above the ceiling and no more than 2 feet of working space. Could you all guide me through exactly where I should and should not insulate? Remember, these rooms are very small but the kneewall area can be reached pretty easy. Please make this simple and easy to understand. I will more than likely become VERY confused if you use any sort of terminology at all. :mad: Finally is R-13 ok in the blue areas? What about the other areas if they apply? Thank you! [IMG]http://i46.photobucket.com/albums/f120/jj200282/room.png[/IMG]
