    I have a kitchen extension at the back if the house. Lean to I think it's called with a tiled roof.

    It has a sloping roof maybe about two feet at the house going down to I suppose very little. Ceiling inside is standard height..

    This is a very cold room. Windows and door are good quality double glazed .

    Im sure there is some insulation in the roof space but clearly it needs more.

    How can I get insulation in there.?

    Maybe I could add an insulation board to the ceiling and then plaster over ...can that be done..

    Any ideas please

    Thanks.

    Hi.

    Are you saying that the roof is only about two foot high off the ceiling? I'm not sure how big a room it is then if it has roof tiles. What dimensions is the room?

    Depending on the height of the rafters, to insulate that well you would probably have to install a rough hatch by cutting a joist or two. I did exactly that for my back-hall and fitted a tight-fitting closure over it to seal it off. Otherwise if the rafters aren't high enough to reach in and install insulation, you would probably need to consider a more drastic option such as pulling the ceiling down or trying to access it by lifting tiles. Messy, I know. I don't think that insulated plasterboard over the top of the existing would be an option here for a variety of reasons.

    I now have 300mm of glasswool at the ceiling level and it's a big change from the previous. The insulation was pushed right out as far as I could get it, but I retained ventilation space as the room does see quite a bit of damp from clothes, etc.

    we have a similar extension and it has also been very cold this week, but there is definitely insulation in the roof and walls in our case (it's the only bit of the house that is properly insulated).

    So maybe look for air leakage - in our case there are draughts coming in under the walls and the extractor fan is poorly installed with a massive hole around the exhaust. An infrared thermometer will tell you if the ceiling is cold, you can borrow a kit from your local library.

    Thanks for replies above...

    I've booked the kit from the library
