The vanishing screens can be used on almost any door and window opening that needs flying insects sealed out. My two most interesting applications have been to keep out birds. The horse stall door screen was installed to keep the birds from flying into the barn startling the horse and possible injuring the owner. The front door hallway application was done to keep the birds from flying into the glass door and injuring themselves. With the vanishing screen installed the birds would fly into a cushioned screen, fall, and fly away uninjured.
