We had really old windows on our victorian home and we heard about magic windows on the radio and saw their ad on tv. We called and a great professional came out to explain how their product works and how it's different from other windows. We now have beautiful windows with no unsightly frames in the middle, screen and blinds built right in! It's such a great convenience, as well as being a gorgeous view now! Thanks to Magic Windows for great service and a great product. There's even a 40 year guarantee which gives more peace of mind!
