Ceiling insulation for bathroom that's cold in winter Information, help, tips and advice on cavity walls, ceilings and lofts etc....

[owen1951]

Good afternoon. I'm after some advice please. I have an old cottage which is as well insulated, walls and roof , as it's likely to get. Many years ago the house doubled as a shop and what is now the bathroom, on the first floor, was a store. It has insulated walls but also the only bit of non-insulated roof, just slates and plasterboard. In winter it's cold , is it possible to add insulation without causing damp problems and if so what is the best method.Thank you

Hi owen1951,
If there is an attic above the bathroom use mineral wool insulation. If the plasterboard is fitted on the rafters use PIR boards fixed through them and new plaster boards on this. Maintain a ventilated space between the rafters.
