The Scottish Performance Film installer was at my home yesterday and installed our Vista window film. The film is almost invisible so I was absolutely amazed today when the sun came out and the heat and glare that used to drive me out of that part of the house was now gone. Everything you told me was true and the product has exceeded my expectations. I almost can’t wait until the summer to find out how much I save on my utility bills. Thanks to all of you.Margie.
