Virtually invisible insulation. Enhance comfort and efficiency year round. Our unique low-e window film helps retain warmth in the winter and cool air in the summer by increasing your windows’ insulation value. A single-pane performs close to a double-pane, a double-pane performs close to a triple-pane.
Virtually invisible, the look of your window barely changes, inside or out. Yet it still helps protect furniture, floors, upholstery and artwork from UV rays that cause fading. Easier and more affordable than replacing your windows, 3M™ Thinsulate™ Window Film is an efficient, cost-effective way to meet your window insulation needs. CONSUMER WARRANTY: Selecting 3M Window Films gives you piece of mind. That's because we have one of the most comprehensive warranties you can get; backed by a company you know and trust. 3M Window Films come with a limited-lifetime warranty when professionally installed on your home.
