Hi guys, hope you can help! We moved into our Victorian terrace in Huddersfield about a year ago now, and the people before hadn't done much, so we've spent this year doing quite a lot of DIY and getting quite a lot of trades in, to do kitchen, bathroom, basement, double glazing and fireplace.
When we moved in, we had a lean-to galley kitchen with an adjacent small dining room, which we've now knocked through into one room to increase the size of the kitchen. Because the original kitchen was so small and dark, at some point someone had created a hole in the ceiling and added a really crap rooflight. It is FREEZING right now, and not needed, because the room is much lighter than before.
My question is, what's the easiest short-term way of patching up this hole so that the kitchen isn't 10 degrees all the time? We are intending to replace the crap plastic ceiling next year with a normal plasterboard ceiling and maybe insulate the little roof above it, but we're just looking for a quick fix to get us through the winter that won't lead to mould problems etc. The hole is only maybe 0.5m x 0.5m, if that. But it makes the whole room freezing. Would a bit of ply with some insulation above work OK, or would condensation form on it?
