<br>
Here are the test-results in detail:<br>
<br>
<b>Danish<br>
</b>U-values from ?-values Measured for 385 mm straw parallel to heat flow, 75 kg / m3<br>
Heat flow parallel to straw: ? = <b>0.057 W / mK<br>

</i><br>
Tests made in <b>Austria </b>for “Haus der Zukunft”-project “Wandsystem aus nachwachsenden Rohstoffen “, 1/2000 in detail:<br>
<br>
MA39 Versuchs– und Forschungsanstalt in Vienna: <b>ÖNORM</b>-tests:<br>
wheat-strawbale: density 90 kg/m3, ?10 dry= 0,0369, + 20%* = R-Value <b>0,0443<br>
</b>wheat-strawbale: density 100 kg/m3, ?10 dry= 0,0340, + 20% = R-Value <b>0,0408<br>
</b>wheat-strawbale: density 110 kg/m3, ?10 dry= 0,0337, + 20% = R-Value <b>0,0404<br>
</b><br>
MA39 Versuchs– und Forschungsanstalt in Vienna: <b>ISO</b>-tests:<br>
wheat-strawbale: density: 90 kg/m3, ?10 dry= 0,0380 W/mK<br>
wheat-strawbale: density: 90 kg/m3, ?20 dry= 0,0394 W/mK<br>
wheat-strawbale density: 90 kg/m3, ?30 dry= 0,0408 W/mK<br>
<br>
*There is a 20% addition for moisture-sensitive materials, so we work with ?10 dry: <b>0,045 W/mK<br>

Tests made in <b>Austria </b>for “Stroh Kompakt”, 8/2005<br>
R-Value at 10 °C av. temp. ?10 W/mK <br>
dry <b>0,045</b> (Nennwert, for at least 90 % of the production)<br>
23°C/50% ? D(23/50) = 0,046<br>
23°C/85% ?10(23/85) = 0,050<br>

> I'm searching for the Danish SB R-value testing results. So I can <br>

> (serious) tests are also welcome. I'm particularly interested to know <br>

> <br>
> What I've found so far (thanks to Bruno Jarno) is :<br>
> Country Dry density<br>
> (kg/m3) Mesured Lambda (W/m.K)<br>
> Germany 90 0,05<br>
> Austria 100,8 0,05<br>
> France env. 70 0,07<br>
