The WindowAlert Performance Series Diamond Anti-Collision Decal is a highly effective, bird-safe solution designed to protect wild birds from dangerous glass collisions by making clear windows and doors visible using advanced UV-reflective technology. Featuring WindowAlert’s bold Performance Series UV-reflecting Diamond design, these decals deliver increased strike protection by creating a bright ultraviolet warning pattern that birds can see while remaining subtle and stylish to the human eye with a frosted or etched appearance. Each pack includes 30 semi-transparent Diamond decals, approximately 1.75 inches across, optimized for a 2 in x 4 in grid installation to create consistent visual coverage across glass surfaces without obstructing your view.
