Using light straw clay (slip straw) as interior wall fill
Good, clear straw/clay tutorial. Put those kids to work!
“An instructional video by Cedar Ridge Farm.

Foamglas Blocks, Gravel and Insulation Board

We’re starting work on the Wiki Natural House project in the UK. At this point it looks like we will use three foam glass products: foam glass blocks, foam glass insulation board under the slab floor and foam glass gravel in the tires. This plus the straw bale walls plus R-40 roof insulation and good windows will give us a superinsulated house.
