Patio doors can add an abundance of natural light, functionality, and atmosphere to any installation, but did you know they can also be paired with transoms and sidelites? Transom windows, geometric ellipticals, and half rounds can be added above your door to increase the amount of natural light that enters the room and add additional character. Sidelights are fixed windows that can be added to the sides of your patio door to increase viewing angles and allow the space to feel more open.
