[Strawbale] Re: Glass bottle insulation

[rikki nitzkin]

Tim,

Your advice is easy to understand. thank you.  I only have about 10 cm for 
insulation so two layers of bottles may be a lot.  It is good to know that 
straw-clay isn´t such a good idea.  I did wonder, but thought that if it was 
in the book . . .Do you know of any other natural/recyclable insulation for 
floors?  I suppose wool is too soft for under a clay floor, and volcanic 
rock has to be purchased. . .
