Hi Andrew

have you considered abandoning the polycarbonate and using the frames for
a polytunnel, covered in UVI stabilised polythene sheeting ? I am about
to do this with mini greenhouse frames for next year.

I am sure you mean well but covering
frames such as these with polythene would be almost as disastrous as the
polycarb.
The edges are far to unrounded and stress tears would soon occur.
Polytunnels are constructed with round bar
and even that needs protective tape where the polythene touches the bar.
The urgency seems to be to stabilise things - either all in or out for the
time being before high winds return.
Even a glass one in this state would succumb !
