I have been renovating an old stone house with a suspended timber floor. After much investigating I have been insultating the walls with sheeps wool and no cavity behind the plasterboard. The stone is two foot thick and dry dashed so is very waterproof. So far this has worked well. Air from under the floor can go up through the breathable wool to the loft space although is restricted more than it was when there was no insulation at all.
The house has a washroom on the back with the same stone walls and a concrete floor. This room is stripped and being reframed with a small cavity and insulated with kingspan. My joiner says I should bore a couple of holes to vent the kit?
My concern with this is that the wall will provide not heat retention from the inside then as the outside air will be between the inside face of the stone and the back face of the kingspan partitions. Effectivly the 2 foot stone wall is then only stopping my partition getting wet!
Can I vent the cavity to the room rather than outside?
Thanks
