Hi folks. I'm having a single storey conservatory replacement room constructed off my kitchen. It's the sort that has velux roof lights on either side of the roof and a flat centre section with two sloping sides with the roof lights in. The ceiling, between the rafters, is having hard insulation put in but the builders haven't put any in the V at the bottom where the rafters meet the soffits, or in the angle where the sloping sides meet the flat section at the top. The rest is filled. Should I insist that the other bits are filled in?
