That is why it needs the support there and why the flying buttress does not even contact the lower part of the walls. Steel bracing supporting the wall in this position is an alternative solution as was discussed earlier, but the problem is that steel is corrosive in a hot moist environment and once covered with insulation is difficult to access to replace or adjust.

Re: Starting my barrel vault
That just means a poorly designed oven to me. What is the exterior going to be?

No, because it is not a mass buttress, it is an adhesion buttress. Without locking the first one in, it will just roll over with the rest of the wall.

Originally posted by gugahulk View PostI already have the blankets so I bought them already might well use them. I am really short on firewood, so the last thing I want to do is ad more mass, if not I would just ad 4 inches of refractory mortar that and that is it. But I am really short on wood on the long run. I dont want to ad any more mass than I have to. What do you think its the best solution for me?

Originally posted by david s View PostI think 5 blankets is overkill. Any more than 2" thick gives provides little additional benefit for the extra cost IMO.
5:1 perlcrete will add a little mass. You can't have both mass and insulation. The stronger you make the perlcrete the heavier and stronger it becomes, but the less insulating it will be.

Originally posted by gugahulk View PostWill adding perlcrete increase my mass? in a ratio of 5 to 1? or it will just work as insulation and strength? Remember I am planning on adding 5 ceramic fiber blankets to the vault. I need to make sure they will work great also keeping everything very insulated. I do have the problem of finding wood so I did not wanted to increase my mass if I didn't have to. Please let me know.
