Hello All ,
last year I got the cavity walls insulated and topped up the loft insulation myself to save energy/ money etc ,but I now seem to have a problem that in all the upstairs rooms at the joint of the ceilings and the walls I am getting a lot of mould spores appearing this isprevalent on the outside walls only .
My question is should the loft insulation go right up to the point where the roof trusses meet the top of the walls or should I leave a gap and if so how big a gap ? .
Its a semi house by the way / and we didnt have this problem last winter
Thx in advance for any replies Glenn
