Definitions

  • This invention relates to glass.
  • the invention relates to bird collision-averting window panes, glass railings or glass barriers that reduce the incidence of birds flying into glass.
  • Some solutions involve substantially eliminating the illumination of a window by such actions as turning out interior lights or closing blinds or other window coverings at night. Turning out lights is not practical where there are persons in the premises at night, and further relies on individuals to remember to take such steps, as does closing window coverings. Outdoor coverings such as bird exclusion netting are not practical for use on high rise buildings due to wind and installation issues.
  • Other solutions involve imprinting or forming the window with a material having an opaque or translucent pattern, which a bird processes as an obstruction, but applying a permanent pattern to the glass itself reduces visibility through the window to humans and occludes outdoor light coming into the structure, even at times when bird collisions are unlikely.

  • the invention further provides a method of reducing incidence of birds colliding with a glass pane in a structure, comprising the steps of: a. coating the pane with at least one layer containing a sufficient quantity of an optical brightener to cause at least some birds to sense the pane as an obstacle and avoid colliding with the window pane, and b. installing the coated glass pane into a frame affixed to the structure.
