The stained glass windows of St. Patrick Church were installed in the church at the time the church was built --- 1915-1917, over 100 years ago. Some 25 or 30 years go, when damage from BB holes was noticed, the windows were covered with Lexan to protect them from further vandalism damage and gradual damage from the elements. At the time the Lexan was installed, it was the recommended clear covering for the window surfaces, and it was used in similar applications all over the country. As the Lexan aged, however, it became apparent that it would not remain clear, and would become increasingly opaque until it looked almost like plywood. It was also found to expand and contract significantly, making a long-term weathertight seal impossible.
