Frequently Asked Questions
About Window Films

How does window film work?
When sunlight comes through your window, both solar heat and UV light is transmitted through your glass. When you apply window film to your window glass, depending on the film you choose, it helps to reject up to 78% of the solar heat and up to 99.9% of the harmful UV rays. As a result, you are able to remain cooler, protect your furnishings from fading, help your air conditioner be more efficient and save on energy costs.

Does the film really work?
Yes. 3M™ Window Films are the most tested films in the industry for heat, glare, and UV protection. The film meets or exceeds independent laboratory standards for performance and visual clarity.

Can window film prevent sun damage and fading?
Yes. In fact, this is one of the main reasons homeowners purchase window film. 3M™ Window Films blocks up to 99.9% of damaging UV rays and up to 78% of solar heat, two of the major causes of fading and sun damage. While nothing can stop complete sun damage, window films will help to protect furnishings by slowing down the effects of fading.
