Twinwall polycarb (plastic glass) (Wallsend NE28)

Hello,
If anyone has any spare twinwall polycarbonate lying around I’d be very grateful to take it off your hands please. The kind you would use in greenhouses or as a clear plastic roofing material.
I built a cold frame with some previously but need some more for the roof. The frame is timber and I will be recessing twinwall into grooves to hopefully make it warm and watertight.

If you have any spare lying around I’d be super grateful to take it away.

Many thanks,
Alex
