Window Strike Solutions

Every year, millions of birds are injured or die after colliding with windows. Window Alert is a decal that reflects ultraviolet sunlight, a light that is invisible to humans but very obvious to birds. Easily apply clings (technically not decals) to your home or office windows and help prevent dangerous window strikes. We recommend placing decals two to four inches from one another and replace decals every 4-9 months as the UV coating will fade over time, depending on exposure, elevation and amount of UV striking your window. You can test the UV reflection by using a WindowAlert UV flashlight or any such flashlight

Place decals on the outside of the window. Concentrate decals at center then work out, placing decals at a minimum, on every 2 feet of glass. For maximum protection, scienti­fic studies suggest placing decals 2 inches horizontal, by 4 inches vertical, from one another. (Eugene WBU owners visited a research facility in PA where the research determining this was done and it was interesting to see how they tested this.)
