The dome I'm in now has 12" thick walls most of the way up, and will continue to the top with 12" thick. While you can reach a point of diminishing returns with insulation, I don't think R36 or so is too much for west Texas at 4,000'. I don't do blocks, though. The dome I'm in has slip formed walls, the "next" one is getting triangular panels that are 3' on a side and 10" thick. A sealing top coat will go over those, getting back up to the target R36.
IMHO the less you handle the papercrete, the easier your project is. I have a pump mounted on the tongue of my mixer, and pump into forms. That way I only have to pick up dry paper and portland cement, but not all that water.

I have overplanned my projest and have a few layers of blocks made. With the end no where near being in sight I was hoping to get some input from folks. My blocks are to big I fear being 16in wide by 8in (6.5 after set) deep. What are the width of blocks out there?? I live in West Texas and insulation from heat is my priority. So I planned on the 16in walls to get to this point. The cost and labor involed in this sized block is more than I had planned with one 200 gallon load making 12 blocks. How thick are you making your walls and the related R factor. I was alwas under the presumption that Papercrete had an average R Factor of 2/in. Rusty. ------------------------------------ Yahoo!
