[Strawbale] Fwd: Futility of quantifying properties of natural materials (was Re: compressing or not

Wasn’t there a fire test in Germany that tested an unplastered bale?  My memory is that they wanted to certify a bare bale wall, so that subsequently, any plaster could be approved for use.  I’m thinking that Dirk mentioned this test recently, in discussing a subsequent fire test with lime plaster.  My memory is that the unplastered bale failed the test/time rating that they were aiming for.

Hi again,

Ok, so not 'unplastered', but 'slightly plastered' (Sounds like me after a night at the pub!)

I'm aware about approx. 5 national fire tests, but due to the cost and the aim they are all done with between 3-5 cm earthen plaster.
The only firetest I'm aware off which actually confirms that a clayslip is sufficient is the one carried out at the final evening of the excellent ESBG07 in Germany. -I just noticed that my hopelessly amateurish filming of it has received 12.986 on youtube!
I don't know if links work in this forum, if not then search for 'Strawbale fire test'

...But I'm afraid it's not going to convince the authorities...

Cheers, Max
