What surprises customers though, is how good these doors look when styled as a French door set. Most customers think that they have to fill a large space with a door in the middle and the glass panels outside but ask your designer to show you how the space would look as French doors. We may surprise you.

You can also choose to have a Solidor door as a stable door. Some of our customers have found this useful when they have limited opening windows and want the additional airflow. This can also be a useful way to keep young children and dogs safe, allowing you to open the top part to take packages or talk to unexpected callers.

There’s also the option to include matching side panels with your chosen Solidor door.
