Hi,

I have a room which is about 14 x 10. It used to be a porch, but the

previous owner enclosed it. The room is finished with drywall for both

the walls and the ceiling. The room has 6 windows and large sliding

glass door which lets in a lot of light. Currently there is no

ductwork run to the room, but I plan on having this done when I get my

furnance replaced. The problem I have is that I was working on

installing a ceiling fan in the room today, and upon removing the old

electrical box, I peeked up into the open space to find that there is

no insulation in there. Obviously this could be a major problem if I

wish to heat/cool the room. So at this point, I'm thinking I have two

options: 1.) demolish the ceiling, insulate as necessary, then put new

drywall up (not an ideal option to say the least) or 2.) use a loose

type insulation such as cellulose and spray it into the ceiling

The roof over this area is slightly angled. Then there are joists that

run parallel that the drywall ceiling is attached to. Because of the

angle of the roof, it appears that there is open space between the roof

and the joists. Would I be able to use the hole (about 4" in diameter)

that is currently exposed for the ceiling fan to blow cellulose

insulation into the ceiling? Would there be any reason I couldn't do

this? What about a vapor barrier since I can't actually put anything

down as I don't have access to the entire ceiling? Also will

ventilation be an issue? Any other suggestions on how I could approach

this?

Thanks.
