Hi
I've got some Rockwool Flexi insulation slabs left over and now need to fill a brick cavity wall that I've had to replace (as bricks were loose) under the bay window. Does anyone know if the flexi insulation can be used between 2 brick walls as the flexi technical data on the Rockwool website doesn't mention this type of cavity?
Thanks
