TIP: For smaller-scale projects, consider some of the methods available for residential use.
Integral applications: Frit and acid-etched patterns
Ceramic frit or acid-etched designs on the first surface (the outermost surface) of the glass can be bird-safe if they meet current bird-safe standards (i.e., CSA standard). These methods are useful primarily for new construction or replacement of entire panes and are generally available in a variety of attractive patterns. Before selecting a product, ensure it has a reasonable warranty.
These are a few glass manufacturers that offer first surface applications.
Applied coverings: Patterns or window films
Glass can have an image or pattern applied to the exterior glass surface. Markers can be of any shape or pattern, but they must meet current bird-safe standards (i.e., CSA standard). Any exterior treatments must withstand exposure to the elements and window cleaning. Before selecting a product, ensure it has a reasonable warranty.
These are some types of bird-safe applications that you may consider in building retrofits or new builds, many of which offer custom designs.
