greenhouse kick boards

[ron]

Hi at the bottom of each window of my greenhouse there is a piece of material approx 6ins by 24 ins by 4mm(thickness of horticultural glass) that is starting to degrade so I am looking for something to replace it. On the bottom of my new washing machine there is a piece of plastic similar to corrogated cardboard which would be an ideal replacement. Does anyone know what that is called and where I could get it in 6ins by 24ins pieces or even a sheet I could cut to size? I will need 13 pieces 6 by 24 and 1 piece 12 by

2. Thanks Ronald
