Pivot doors suit oversized single entries. Lift-and-slide doors give the tightest seal of the sliding systems and handle very tall, heavy panels. Multi-slide doors open long walls and clear up to 100% of the opening when panels slide into a wall pocket. Bi-fold doors fold to one side and open about 90% of a mid-size opening, but need room for the folded stack.
| Widest clear opening | Multi-slide with pocket (up to 100%) |
|---|---|
| Best weather seal (sliding) | Lift-and-slide |
| Mid-size opening, fully open | Bi-fold (about 90%) |
| Statement entry | Pivot |
Side by side
| Pivot | Lift-and-slide | Multi-slide | Bi-fold | |
|---|---|---|---|---|
| How it moves | Leaf turns on a floor pivot | Lifts off seals, slides | Panels slide past each other | Panels fold and stack |
| Clear opening | Most of the leaf width | About half with 2 panels | Up to 100% with a pocket | About 90% |
| Weather seal | Depends on seals and threshold | Very tight when closed | Good; depends on product | More joints between panels |
| Space needed | Swing space both sides | None | Stack or pocket at the side | Room for the stack |
| Partial opening | Any angle | Lock at any point along the track | Any panel position | Usually a traffic door |
| Critical install point | Level floor pivot, threshold drainage | Level sill, stiff header | Straight tracks, pocket framing | Stiff header or level sill |
| Best for | Front entries | Tall glass, tight seal | Long openings | Mid-size openings |
In one manufacturer's published test data cited on GreenBuildingAdvisor, its lift-and-slide door leaked about 0.02 cfm/ft² of air at the lower test pressure, compared with 0.14 cfm/ft² for its standard sliding door. Compare the NFRC or test ratings of the specific products you are considering.
How to choose
- Front door, big statement: pivot. See pivot doors and what they cost.
- Tall glass to a patio, year-round use: lift-and-slide. See lift-and-slide doors.
- A whole wall that disappears: multi-slide with a pocket. See multi-slide doors.
- Mid-size opening you want fully open: bi-fold. See bi-fold doors.
What changes at install
Every one of these systems depends on the opening: a header that doesn't sag, a sill that's level for its whole length, and drainage under the threshold.
Questions
Which is better, lift-and-slide or multi-slide?
Lift-and-slide when you want the tightest seal and very tall panels; multi-slide when you want more panels moving and a fully open wall at a lower cost per foot.
Do bi-fold doors leak?
A well-installed bi-fold with a drained sill and adjusted seals performs well. Leaks usually come from a missing sill pan or panels out of adjustment.
Can a pivot door be a back door to the patio?
Yes, if there is swing space and the threshold is detailed for water, but sliding systems are more common for patios.
Which one needs the most maintenance?
Systems with more moving parts, like bi-folds and pivots with hydraulic closers, need more periodic adjustment than a fixed-track slider.
