3M Thinsulate Window Film

Home / 3M Thinsulate Window Film

3M™ Thinsulate™ Window Films help to add an extra pane of glass at a fraction of the cost of window replacement.

Thinsulate™ technology and components have been integrated into many jackets, hats, gloves, shoes, and bedding; and as such, the brand has become synonymous with insulation and warmth. Now the brand includes window film.

3M Thinsulate Window Films represent the latest in window film technology. Not only do these films help to block out the sun’s heat in the summer, but they also help to trap manmade heat inside during the winter, providing you year round comfort.

All season window films, otherwise known as low emissivity or Low-E window films, are nothing new. In fact, 3M patented the idea in the 1970s. Those films of yesterday were highly reflective, giving the windows of your home or building a mirrored look. 3M’s new Thinsulate Window Films offer similar performance but are virtually clear and colorless.
