Hi all,
I am thinking of doing a non habitable attic conversion just to provide more accessible storage and also a playroom for the kids. So essentially it's a case of strengthening the floor in places where there is a very large span and insulating / plasterboarding the rafters. The attic itself is an old style perlin construction, so the entire attic space is open bar a strengthening cross piece 2/3 the way down the house which I'm not going to touch.
Heating would just be when it's in use (ie. an electric convection), so my main concern is the health of the timbers, the job itself is just making the attic space more pleasant to be in!
My initial thought is something like 100mm of insulation below the rafters and plasterboard on top. Or perhaps less insulation given the time the space would be in use.
Does anyone have any knowledge of issues with damp when converting a cold attic in this way? Would additional batons across the rafters between the rafters and insulation / plasterboard be of any use in increasing ventilation around the timbers?
Thanks!
