The selection of bifold door styles are the same as with traditional swing doors, with the exception of the type of hardware needed. Bifold doors are available in the typical hollow core interior style, which makes them an economical and lightweight choice. Durable and easy to install, bifold doors don't have to be drab looking. Some hollow core styles include decorative features such as raised panels, which add a stylish touch. There is also a variety of wood veneers available such as mahogany, maple and oak.
