How about lacing in a new piece of poly? Mind you, that sounds a real
challenge to the system.


I have a replacement cover, which is going to be put on at some point.
Replacing bits would be slight overkill.
However, on one end, it's probably going to get the old cover moved inside,
to form double glazing.

That sounds good. If you could get some bubble wrap, you could perhaps
put it between the two layers of poly and improve the double glazing
effect still further.
