Sliding patio door
A patio door with panels that glide horizontally on a track — one fixed, one sliding.
What it means for you
The space-saving value choice: nothing swings into the room or onto the patio. The overlap where the moving panel meets the fixed one is the leak point on cheap units, so a quality “reach-out” lock that pulls the panel tight to the frame is what keeps it sealed.
Where you'll see it
The default patio-door option; priced below French doors.
Also sold as: patio slider
