In some of our animal outbuildings the walls are lined with a white, thermal lining sheet. It is made from a very soft and easy to cut plastic, in sheets of 6x4 ft and has a twin wall construction. It is about 3 or 4 mm thick. It is not a hard polycarbonate sheet. I need to replace some ( badly scratched and ripped ) but can't find any so does anyone have any idea what it might be and any trade name for it. It has a thermal property and is easy to wipe clean and put clout nails through.
I know, hard to identify from a description. Thanks
