I hadn't thought about traped air. I know that just being up on a ladder under roof, or on top of a roof, it's allot warmer!!!! I can see where that air can contribute to the overall warmer tempature of the gazebo, which I'd like to avoid.
I really want to put the glass blocks in the cupola, so now I'm wondering if another cupola on top of the main one with vents might be an idea. I don't have any problems with going a little overboard on this if I can get the results I'm after.
Maybe an eight sided cupola with two glass blocks on each side, then a four sided one on top of that with vents on all four sides? Then top it off with a weather vane?
I'm going to have a roof with two levels to it anyway, so what's one more feature? hahaha
Right now I'm just waiting for the ground to dry up enough to finish off building the pads so I can pour concrete. When I can get that done, I'll start a thread on the square one first. Then after that, I'll build the eight sided one. My goal is to have them done before everyone gets here in October for the get together we're hosting here.
