So I have this window on my porch. It's in a wood frame and really should have been replaced with the screen frame for summer. Meanwhile I think a bird (fortunately no corpse to be found) must have crashed into it because it is all crazed / shattered but still in the frame. I want to take it down to get it repaired but I don't want a thousand pieces of glass either in the porch or out in the garden when I move it.

Does anyone know a way to avoid that? Is there a sort of film I could put on it to catch the glass on each side?

I know this is really off topic but I will be grateful for anyone's advice here!
