Winter Energy Saving Film
Window insulation kits that seal out winter drafts.
Low-E window film
Low-E film keeps heat in during winter and out in summer. We're deciding whether to bring it back: leave your email and we'll let you know if it returns.
Check your glass first: factory low-E or double-pane windows need a film made for them, so ask us before ordering any film for those.
Choosing window film for your home
Start with what you want the film to do, then pick a shade. Every film is cut to the window sizes you enter, so it arrives ready to apply.
- Cut heat and glare Solar films keep out up to 85% of the sun's heat and block 99% of UV, which fades floors and furniture.Solar & privacy films →
- Daytime privacy Silver and reflective films look like a mirror from outside in daylight. At night, with lights on inside, people can see in.Reflective films →
- Privacy that lets light in Frosted and textured films blur the view for bathrooms, doors and sidelights while keeping rooms bright.Frosted films →
- Pattern and style Stripes, blinds, rice paper and floral designs for glass walls, offices and storefronts.Decorative films →
- Winter drafts Window insulation kits keep warm air in and cold drafts out, for one window or four.Insulation kits →
Choosing a shade
Each shade is named for roughly how much daylight it lets through. Lighter shades keep the view and most of the light; darker shades reject more heat and glare but make rooms darker.
For example, Nano Ultra Vision 70 lets in 67% of daylight and keeps out 40% of the sun's heat; Nano Ultra Vision 40 lets in 38% and keeps out 60%. Compare every film →
How to measure
- Measure the visible glass of each window, inside the frame or rubber seal, in inches.
- Enter width and height for each window; we cut the film to the size you enter.
- Each window is priced rounded up to the next whole square foot.
