Re: [Ekodum] difuzně otevřená konstrukce

[danielgrmela AT email.cz]

A mohl bys nám Maxi ty problémy s OSB ve slaměných domech prosím tě 
přiblížit. Aspoň ve zkratce. Či nahodit odkaz na konkrétní příspěvek. Já to v 
tom archivu diskuzí nemůžu najít, pravda, že jsem tomu moc nedal, máš li to 
po ruce, přijde mi škoda ztrácet hledáním čas.

Děkuji.
