Here is a shot of some of my framework. I built each wall as a section, using standard 2X4's that I cut a little shoulder into with my bench saw. I cut this shoulder on both the outside and inside. Then I tacked strips to the top and bottom plate that aligns with these shoulders.This allows me to add glass on the inside in winter if need be to save on heat. On the outside I simply put 6 pieces of butyl equally spaced on this shoulder then apply window caulking and insert the piece of glass. Finally I screw a furring strip between the pieces of glass. The glass in the roof sets on the rafters with the rear of glass under the shingle overhang. The furring strips are notched so that when screwed tight to rafter there is still a little gap which I put caulking before screwing down. This gap allows the glass to move as it expands and contracts.
