Thank you John for replying
I have double glazing, draft excluders and loft insulation.
The chimneys are a big part of the room and the room is so cold.
The Chimneys themselves are cold to touch and in one room we have a picture on a breast and its going mouldy on the back of the picture
My house gets really cold and I really need to insulate the chimneys.
I haven't got a lot of cash, I don't mind hard work and having a go
I have two chimney breasts where the fire places have been removed and plastered over.
Both chimney breasts start downstairs go through the first floor...
