Hello, building a "conservatory" for year-round use; all sides are glass except for the house facade, of course. I have 2 broken corners, one with glass and the other a wall since a stove is going to be placed there. I've now enclosed the small corner with horizontal paneling. My question is, I was thinking of having a stone slate wall on the inside, but I need to insulate this wall behind it, which is 90 wide and 200 high. Is there any trick to avoid an air gap?
