Hi, I would like to ask about what would be a good way to insulate the loft. The loft is not heated and you can feel the air coming into the loft through gaps between tiles as visible on the photos. I was thinking of puting the thermal foil on that but heard that there might be a lot of condensation there which I would like to avoid. What would you recommend for roof like that? How could I insulate it and avoid condensation without much hassle and changing tiles etc?
