I need to rebuild my garages people entry small back door. I rebuilt it some 12 to 15 years ago with ply, which a local hardware supplier suggested was suitable, but now it is de-laminating and needs to be rebuilt.
It will be in the weather 24/7, what is recommended please - the look of it is not that important?
Do they do a plastic panel which might be better - I have in mind that type of L shaped expanded plastic, about 6mm thick, as used for modern house facias, but a flat, door sized piece of that.
