Hi @MikeyPotts , sorry Iām very late with this question. From your posts I see the first layer was 100mm which included the hemp. I assume that layer is the one that gives the insulation and the follow on scratch coat and finishing coat are just to finish the interior?
Finally, how does this compare with āregularā insulation in terms of efficiency, U-values or whatever?
Thanks, M.
Hi Mike
Yes, this will be the background for the scratch and finish.
I actually donāt know what the thermal performance will beā¦in this small sample patch, I was just wanting to experiment.
I think that there is loads of technical info on thermal performance if you do a search?
Cheers for now.

Thanks @MikeyPotts - an interesting experiment to do. I saw something somewhere on YouTube about an English architect who lives in Brittany who used this system to insulate a large townhouse. If I can find a link, Iāll post it here.
Cāest 
!ā¦actually, itās not rocket science and just requires (to do it in situ on a big scale), a decent horizontal mixer and if course, really good carpentry skills to make the formwork and finallyā¦.sweat and muscle.
Today the āpeopleā arrived to commence the insulation of the ceilingsā¦4 weeks of work to come but hopefully afterwards, cosy toasty toasty :). All of the windows are replaced now.
(All part of the Ma prime Renov thing)
