Hello.<br>
The German certificates (see here attached the german and french
version of theses documents) indicates a value of:<br>
lambda = 0.052 perpendicularly to straw fibbers direction<br>
lambda = 0.080 in straw fibbers direction,<br>

type="cite">the conversion I have used is that R value (imperial)
ft2*degF/Btu = 5.86 X R value (metric) in m2 *degC/W for the same
thickness of material - an easy way of converting R values from
imperial top metric to another for the same construction - it also
helps demolish extravagant insulation claims made for some
american materials when proponents have not done the conversion.

<div>10.05 * 5.86 / 39.37 inches/m = 1.49 so its close<br>
