What Is a Multi-Slide Window?

A multi-slide window is a row of glass panels set in one frame. Each panel rides on its own track. Slide them open and they stack behind one another at one side, or at both sides if the window opens from the middle.

Think of a multi-slide patio door sized to sit on your kitchen counter instead of the floor. Most go in as a pass-through window between the kitchen and the patio, a bar or an outdoor kitchen to easily pass food and beverages through for a party. The panels move sideways, in line with the wall. Nothing swings into the yard or hangs overhead. That makes a multi-slide a good fit when a grill or a walkway sits right outside the window.

How Much of the Window Opens?

The width of the window and the width you can pass through are two different numbers. Slide the panels open and they stack behind one another at one or both ends. That stack still covers part of the opening. More panels make each stack narrower and the clear opening wider, but each added panel also makes the frame deeper.

Want the full width open? A bi-folding window folds its panels to the side instead. We lay out the panel count, which way they slide and where they stack before you order.

Multi-Slide vs. Other Pass-Through Windows

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 strut awning windows are one big pane that lifts up and out of the way. The size of a gas strut awning window is limited by its weight. Open, one sticks out about as far as it is tall. A multi-slide needs no room in front of the window. See gas strut awning windows.
  • Fold-up windows fold in half as they lift, so they stick out half as far as a gas strut awning window. They still need room in front and overhead. See fold-up windows.
  • A miniature sliding door window has one panel that slides past a fixed one, and it has a rolling screen. It opens about half the width. A multi-slide gives at least a 2/3rd opening or more in the wall. See our sliding doors.

Multi-Slide Windows Over a Kitchen or Bar Counter

A multi-slide window has a sill, the bottom of the frame. When the panels are closed, it keeps out rain, dust, hot air and bugs.

The window sits in your wall’s wood framing or block, not on the counter. That means the counter height may cover some of the window’s sill, making the transition from inside to outside a little smoother. For a clean look, you can order a countertop that meets up flush with the track on the inside.

A multi-slide works well over a long counter. You don’t have to open every panel. Slide open the end where people gather and keep the rest closed on a hot afternoon. A bar ledge on the patio side gives guests a place to set a drink or pull up a stool.

How We Install a Multi-Slide Window in Stucco and Block Walls

Most multi-slides need a wider opening than the old kitchen window. Our window installers cut the opening to size and add a header, the beam that carries the wall above it. Then we set the window, seal it, and patch the drywall, texture and stucco.

Wall depth matters too. Each panel rides on its own track, so every added panel makes the frame deeper. Your wall may be built with 2x4s, 2x6s or masonry block. We check its depth when we measure and pick a system that fits it.

Our window installers are our own employees, paid by the hour, so they take the time to get it right. If you have an HOA, we help with the application and approval. See how we handle each type of home on Our Process.

Frames and Glass

Ambassador aluminum multi-slide windowWe 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.

A multi-slide is mostly glass, and a kitchen wall facing west takes the full afternoon sun. We’ll go over the glass choices for each line and which Low-E coating keeps the most heat out. Our glass types guide compares the coatings.
