I spent a bit of time and effort a year or two back putting kingspan (or something similar) between the rafters of my detached brick and breeze block garage (a small double) in the hope of making it habitable in the winter. I'm afraid it didn't make a jot of difference, and without some sort of space heater, for which I don't have space, the only way to keep semi-warm is to run a small oil-filled heater which I pretty much stand on top of. Not really workable. I thought about installing a 'ceiling'. but I store a lot of stuff in the roof void and it isn't quite big enough to make a loft out of.
With this in mind I turned my attention to my small lean-to shed, which was essentially a wobbly pile of concrete blocks. The wall was taken down and rebuilt with a single skin of reclaimed brick. The space is adequate for odd jobs such as a gearbox strip-down and rebuild, and warms up nicely with an old Aladdin stove. The roof however is corrugated PVC sheet and the warm, moist air - even without the heater - condenses on it in cold weather giving rise to a modest indoor rain storm. The space is copiously ventilated. I suppose the answer is an insulated roof, so that the interior surface is not so cold? I have a small wooden double-glazed conservatory close by and it is dry as a bone, but the roof is twin-skinned: Corotherm perhaps. I like the PVC roof as it is transparent and lets in bags of natural light, but any ideas on how to stop the indoor rain would be welcome.
