<DIV></DIV>Hello Jan,
<DIV></DIV>
<DIV></DIV>Jan: maybe a pre-test could be done in
<DIV></DIV>> amateur conditions, before a test in a certified laboratory would be paid
<DIV></DIV>> for. I am sure that some union of shepherds would be able to pay for it,
<DIV></DIV>> even here in Czechia.
<DIV></DIV>
<DIV></DIV>Harald:
<DIV></DIV>We took 10 : 1 ratio of sheepwool to dry borax. The borax had a
<DIV></DIV>wholesale price of 1 Euro/ kg the sheepwool cost us 25 Cent/kg.
<DIV></DIV>Total cost for a 15 m2 studio with a 15 cm roof insulation thickness:
<DIV></DIV>200 kg wool : 50 Euro
<DIV></DIV>20 kg borax: 20 Euro
