Re: [GBlist] Raw sheep wool insulation

[Peter <pelliott@xtra.co.nz>]

The wool will release oils into claddings, so you have to make sure it's not in contact with any permeable internal claddings 
like Gypsum based boards, otherwise your walls inside will get great oils stains on them.

Don't know if it'll settle, probably will given it's raw weight - maybe better to tease it out (seperate the fibres).
