the condensation prob i had in the loft has gone for now, i removed the kingspan from the roof and it compleatly dried out , when using the shower i have closed the door and opened the window. i have since put the kingspan back but incresed the airgap from 35 mm to approx 60 mm and taped up the joints, i will put a polythene sheet up between the kingspan and t and g soon. i have also ordered a extractor fan. if this has solved the problem do u think i should increase the airgap on the south facing roof cause this has never had condensation ?
