After having a conservatory built by another company, although I'd had reflective roof panels and windows it was far too hot having a south facing garden. I didn't really want to pay out for another roof on a new conservatory, on looking around I saw that CC installed inside only, I had this fitted and as my glass is tinted it doesn't show too much from the outside. It turned my 'glass house' into a room and when winter arrived if I leave the door open to the house I don't need any further heating other than from the house. Definitely turned into an extra room
