Installing plexiglass on screen door

Don't know if screen doors are all the same but with ours, you can take the frames apart by removing screws. The screen material sits in a frame about the same thickness as plexiglass. I have some lexan (polycarbonate) sitting in our garage waiting to be installed in our 2 entry doors and am going to take the screen door frames apart to do it.

Optix is a brand name of acrylic/plexiglass. Plexiglass versus polycarbonate. If you go to a plastics shop, they may have some leftover pieces that will work for less cost and they can cut it to size for you without scratching it.
