When asking a neighbor about it, that room was a child's room who in their younger years had tantrums and would throw things at the window. After the glass windows were replaced a couple times (once in the winter which was pricy for a "need to fix this today"), the parents replaced the windows with a rather durable plexiglass. They didn't break again, but they got scuffed up until the child outgrew the tantrums and the house was later sold.
Having something that is potentially more energy efficient (lower thermal transmission) and more durable are existing problems that this could provide a solution or a direction for future solutions.
