Sliding doors
One large panel rolls past a fixed one, so nothing swings into the room or onto the deck. That makes a slider the right call where floor space is tight, where furniture is close to the opening, or where you just want the simplest operation. The trade-offs: half the opening is always glass that does not move, the screen takes wear, and an old single-latch slider is not very secure — a modern one with a multi-point lock and a foot bolt is.
French doors
Hinged glass doors, single or in a pair. A pair gives a wide, symmetrical opening and the tightest seal of the two options, because the locking hardware pulls the active door against the frame and the astragal. They feel substantial. The trade-off is swing space: the panels need a clear arc, inside or out, and that has to be planned around traffic and furniture.
How to decide
Measure the floor space first. If a pair of doors cannot swing clear without hitting something, choose a slider. If they can, decide on look and feel: French doors for a traditional, solid, tight-sealing opening; a slider for a low-footprint, low-effort one. At the free estimate we will measure the opening and the room and walk through it with you.
