Hello, could you advise me on whether using cedar is correct for building some bifold external doors and some windows for a workshop facelift which I am embarking on. I have been researching the rails and hinges required for the bifold doors and the products are available but at a large price tag. I need to have the weight taken by a floor rail rather than top hung which seems more common, but I would welcome any ideas on less expensive options for achieving reliable smooth running bifold doors. Thanks
