lovely stuff aint it,im in the middle of destroying a load of internal walls made up of this stuff,hessian scrim then plasterd,and nailed with 4" wire nails,even the skirtings they used 4"ovals.
RECIP SAW seems to be working a treat,find the joint line then cut through it,then as said use a LONG wrecking bar.
House with strammit board internal walls - would it have a metal frame and a low pitch roof aswell with a kind of render on some and tilehanging on others
. Just that I remember doing a job in one of the houses way back - it was a nightmare to fix any thing - there was a small number of them in a group , not far from Eastbourne
. Surely not more than one outcrop of such strange buildings in Sussex
