Until recently, most window films that rejected heat were tinted dark, used metal or were highly reflective. One of the major drawbacks of traditional widow films is that they tend to act like mirrors. From the inside, traditional window films make it difficult to see outside, especially at night when the interior lights are on. In the daytime, the outside reflection tends to give a home the look of a commercial building.
Over the years, various other companies have tried to create clear window film with mixed results. While they were able to achieve improved performance their drawbacks made them unacceptable for most fine homes. Because these films used metal, they were susceptible to corrosion in costal environments and interfered with mobile phone reception. 3M Prestige Window Films use no metals and are the first films to offer a variety of selections that eliminate these problems and perform to the industry's highest standard. With 3M Prestige Window Films, your home's exterior stays beautiful and from the interior, your view is as clear as your original window.
