Just realised the sheet of secondary glazing film on the window over
the front door is now 31 years old. It's the sort you stretch and
stick to the frame with double sided tape, and then use a hair drier
to shrink the wrinkles out.

Still looks pretty invisible.

Never thought it would outlast the original real double glazing.
