[GSBN] Fwd: [nbne] R-value of compressed straw panels

[asbn]

Yes, we measure just with λ in Europe, so I did't fugure out the  
difference.

But Ecopanely writes in their flyer:
> λ = 0,099 Wm-1 K-1
which means W/m.K
but in the same line
> R = 0,5858 m2 KW-1
which means m2/KW
Is this the U-value (W/m2.K) converted?

kind regards
Herbert
