hi john:

thanks for the details. do you - or anyone else on the list - have any
experience with no-fines concrete? (as described by ken kern) it is
supposedly doing a better job in insulation due to airspaces in it.

also: does anyone have experience with woodcement? especially the
water-insulating stuff, where bitumen-emulsion is used as liquid? (again ken
kern describes this as possibility for a floor slab - could be weight-rolled
to take on a gloss - black glossy floor, insulating + thermal mass - sounds
tempting...  in quite old austrian city houses (200 years +) i have seen old
woodcement-floors - brown and glossy, very nice feel to them - without the
bitumen though, it was up in a third floor, so damp insulation didnt matter.
remarkably durable.
