Every pass-through style trades something. Here’s how a multi-slide compares with the others we install.
- Bi-folding windows fold like an accordion and can clear the whole opening. The folded panels stick out about 3 feet at the side, depending on the size of each sash. A multi-slide stays flat in the wall but leaves its stacked panels in part of the opening. See bi-folding windows.
- Gas piston awning windows are one big pane that lifts up and out of the way. Open, one sticks out about as far as it is tall. A multi-slide needs no room in front of the window. See gas piston awning windows.
- Fold-up windows fold in half as they lift, so they stick out half as far as a gas piston awning window. They still need room in front and overhead. See fold-up windows.
- A single slider or miniature sliding door has one panel that slides past a fixed one. It opens about half the width. A multi-slide opens more of a long wall. See our sliding doors.


A multi-slide window over your kitchen counter turns the counter into a serving bar. Slide the panels open and you can pass plates and drinks straight out to the patio.
We install many types and brands of multi-slide windows, in vinyl, thermally broken aluminum and clad wood. Thermally broken aluminum has an insulating barrier inside the frame that slows heat moving through the metal. Sizes, panel counts and colors depend on the line, so we’ll show you the ones that fit your opening and your wall.
