Hi,
Looking for advice as I prepare to insulate our solid stone walls (~50cm thick) with 40mm wood fibre board.
The first walls we'll be doing are in the rooms on the gable end which is subject to a decent amount of rain in the winter months. I've been in contact with Mike Wye about the different systems that can be used. One method is to attach the wood fibre boards directly to the wall after the levelling coat has been applied and the other is to use a frame work, with wood fibre in-between the frame, followed membrane, wood wool boards and then finishing plaster.
Does anyone have advice / experience on which of these systems would be better for gable end walls which take the brunt of the wet weather? Or would it even be advisable to build a cavity to allow airflow if this carried through all the way to the loft? I'm a bit worried about recent posts which show the wood fibre boards getting damp and worry if they are in direct contact with the masonry, that they'll reduce thermal performance or worse, fail over time.
Any advice would be appreciated.
