Ive noticed the rear bedroom in my house, due to the very cold weather is getting more colder internally. Its a exposed annexe attached to the rest of the house but detached from any neighbours property. so essential the external is exposed on all 3 sides without a sharing a neighbouring wall.
I'd like to know from anyone who has done similar or in the building trade of best solutions to insulate/clad from the outside. Internally not a option as all decorated so a option im looking at is to insulate and clad from the outside.
Its not a particularly large area but its causing enough annoyance and discomfort for me to do something about it.
Thanks in advance for any contributions.
