Hi, I am looking at potentially installing insulated plasterboard on outside facing walls.
I have two rooms on the first floor that are exposed on 2 sides and are by far the coldest rooms in the house. I am about to remove the carpets and install new flooring, sand/plaster were required and refinish. I am wondering if there is a good time to potentially install some insulated plasterboard on the outside facing walls of each room.
I have an unfilled cavity wall Stone (outside) - Gap - Brick wall (inside), is there any reason I should not do this? Anything in particular I should be mindful off?
