Hello, I have an arch where the upper corners are rounded with a radius of ~30cm. On the inside of the arch, there is plywood today, ~5-6mm thick. However, I have had to remove part of it and want to replace the whole with new plywood. The sheet/arch is 30cm deep.
Is plywood bendable with a radius of 30cm or does it require some form of treatment before it can be bent to that radius?
