Hi, I'm new to this site but I have a basic question about orangeries & conservatories. I want to add a conservatory to my house, but I'm concerned about saving energy and being as green as I can and also trying to save a bit on fuel bills. I have found a lovely company that makes conservatories and orangeries in Cornwall where I live and they tell me an orangery might be better as it has a lower glass ratio. They also use the most energy efficient glass. I just wanted to get another opinion before I make my decision on this. This is the company I'm talking to - http://www.conservatoriesincornwall.com/orangeries-cornwall.html
