WindowAlert Hawk Decal
WindowAlert decals help prevent wild birds from accidentally striking windows. Each decal has a special coating that reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but birds see it as a brilliant glow much like a stoplight.
WindowAlert decals are designed for use on exterior glass surfaces. Ensure the application surface is free of overlays, films, and coatings and has been thoroughly cleaned and is free of chemicals. Ideally applied when wether is above 50˚F.
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.
UV coating will fade based on exposure and local elevation. For best results, replace decals every 4 months. Each decal is approximately 5" x 8" inches.
