I had a conservatory that was cold in the winter and extremely hot in the summer. Following my research, we had to decide whether to go with the self-cleaning and heat reflecting glass or a tiled insulated roof. The surveyor visited us and provided a very competitive quote. He promised that the Insulated roof would give us what we wanted which was a warm room that we could still use in the winter months. Up to the day of installation I was still in doubt as to whether the insulated roof would work albeit all the reviews I'd read about Tiled Roof Conservatories were positive. I am very pleased to say that when the cold evenings kicked in, I'm able to sit comfortably in my conservatory. My thanks also go out to the installation guys. Although I was away when the roof was installed, my husband provided me with a step by step guide of your professionalism, organisation and structured process from the beginning right through to completion. We have now been using the conservatory for over a year now with the Tiled Roof and we use it every day no matter the weather outside. J. Anderson
