@meredith You may have trouble with getting this data since being DIY every batch is different. I hope something comes through though. How about a ferrocement outer shell with insulative brick on the inside? That may get you permitting....goodluck
@vitusthemad no real set formula but we do it like that to fit human scale. The equator at this heigth makes for a dome that allows for more head room Near the walls and ceilings. It would make sense to make a higher equator as the dome size increases. I know that smaller domes use shorter equators to keep bricks from angling too steeply at the base...
@Kintore Hi, imagine you are in a hemisphere and walk towards the perimeter. How close can you get before bumping your head. This is one of the biggest benefits of the Domegaia solution - you gain all that space under the curve. The other benefit is aesthetic - it looks beaut!
@Samson-Jones If you have not already tried this. I would say aircrete used directly as flooring will flake off a dangerous to inhale dust. So no, I would certainly coat it with a "milk" layer that includes laytex.
