We have a large conservatory that we just couldn’t use in the cold of winter or on a hot summers day. We decided on a Guardian Roof after reading reports from others, and, we can honestly say, since it was fitted we have been able to sit in the conservatory even on the hottest day, it’s a joy to have a lovely room we can all use. The work was carried out professionally by Windows by Design of Swindon and we can thoroughly recommend them.”
