A two-paneled door has more space, which is a great benefit if you have to move large objects through the patio. There are many other options to choose from.

French doors are the most expensive types of patio doors. They are hinged in the middle and are installed in the same way as a normal door. The French door is secured to the doorframe with two to three hinges, while a sliding one is fixed to the wall. During installation, it is important to measure the height of the doorway to ensure that the frame is sturdy enough to hold the weight of the second. Otherwise, the screws may come loose and cause damage to the frame.
