Dear All,<br>
<br>
I have in interesting information. I have spoken to a guy who does<br>
natural plastering for over 20 years and he said that the houses in<br>
Austria which he worked on 20 years ago show problems now. The plaster<br>
which was applied directly to the strawbales on the outside is cracking<br>
and falling off and they found out because over the years some moisture<br>
got inside the straw and made it crumble and dissolve. So the house is<br>
no good now and there is no easy way to repair it. I wouldn`t like my<br>
house to live the same misfortune in cca 20 years time. This is why<br>
vapour barrier and wind proof facade is a good solution. I can`t wait to<br>
hear your comments.<br>
<br>
Cheers<br>
<br>
Jure<br>

> I read people objecting agains using sheet material instead of rendering the bales directly. The reasoning seems to be mainly relating fire protection and sealing air leaks. Yet, lot's of people use bales in their roofs. I'm assuming none of them would render the underside of these bales. So why do it for wall's if it's not done for the roof? Any thoughts?<br>
