I am thinking of improving the insulation of my conservatory by having a tiled roof fitted. That does not seem to be problem but would I be able to cover some of the glass sides with cladding and, if so, would I need planning permission? It will end up looking like a brick extension rather than a conservatory.
Why not fit high U value insulation to board first to your outside skin and cover this with stone or brick cladding. Contact these guys will give you full instructions at www.fossil-stone.co.uk. This will give you great insulation as some stone cladding will give very little to none.
