I have a 14 ft high vaulted ceiling. I plan to run the chimney of the stove through the highest point and directly through the peak in the ceiling. Also I plan to put natural stone mosaic up the entire height of the wall, from floor to ceiling, and it will be about 3 feet wide. The backing for the stone mosaic will be concrete board that has about an inch gap between the board and the drywall for cooling and air flow. The board will be secured to the studs and the spacers for the inch of space will be ceramic. My first question is will the concrete board be enough to support the weight of the stone mosaic all the way up the wall? My fear is that even if it is properly secured to the studs, the weight of 14 feet x 3 feet of stone mosaic (even though it is small almost pebble stone) will break the concrete board and cause the whole thing to come down. Do you think this would be a problem too if I didnâ€™t do the air space, increased clearance to the stove and put the stone mosaic direct on the drywall? Would the weight of the stone mosaic be too much for the drywall? I have not put tile or stone mosaic all the way up a wall like this and I am worried about the weight of it and the wall being able to handle it. The attachment of the stone directly to the wall is different than say brick because the wall takes all the weight of the stone while the brick bears some of its own weight. Thoughts?
