Corrugated clear plastic roofing sheets (Saltdean BN2)

The glazing in my cloche frames is made from corrugated (or flat flexible but not double walled) clear acrylic or plastic roofing sheets, and several got smashed in the recent storms. Has anyone got any spare bits minimum size 1145mm (45 1/8”) x 390mm (15 7/16”) but bigger is fine as I can cut it. A few screw holes don’t matter, and if the sheets are bigger, then any damaged edges can be easily cut off. Many thanks for your time.
