Re: GSBN:STC for bale walls
As Matts writes below we have done one test in Denmark. A "field" test on an existing house. Only one test. No lab-tests.
As the results are not yet public and I want to stay on good terms with the Danish National Building Test Institute you will have to excuse me for not saying more right now.
I will though ask mr Official man whether I may let it slip out into the open.
As Andr? points out the results are not fantastic, eg just not good enough for a dividing wall between two semidetached houses, unless a thicker plaster layer is applied.
