I have been a lurker on these forums for awhile and have used the info found on this site for many projects around the house. Now, I've got an issue that I would like to get some opinions on.
I have a 12'x20' shed in my backyard that I have recently converted into a workshop/"man-cave" . With a brutal Houston summer just around the corner I need to figure out the best means to insulate the building. The shed is all wood with short walls and a "barn style" rounded type roof. In other words, it's almost all roof. Luckily, there are trees shading a good portion of the roof but even a few hours of sun beating down will turn the shed into an oven.
Initially I was just going to use fiberglass batts as it looked easy to install and is relatively cheap. Now I'm wondering if I would be better off using a radiant barrier. The roof has 2x4 rafters spaced at 24" with, of course, plywood roof decking. You can really feel the heat radiating down from the plywood after a few hours of sun.
I have a roll of foil radiant barrier that I could use right now, but I would be more than willing to buy something better if needed. One reason I am hesitant to use a radiant barrier is that I'm not sure if I'll like the look of so much silver foil in a space I'll be spending some considerable time in. But in the end, I want to be comfortable spending time in there during the summer months (cold weather is not much of a consideration). Also, I do have a decent window AC unit installed to pump in cold air.
So, anyone have any insight on what would serve my needs best?
