Combine three window units into one larger configuration to create the right balance of ventilation, natural light, views, and architectural style for your home.
A three-unit combination joins three individual window units — for example, operable windows flanking a fixed picture window — into one larger opening. The units are mulled (joined) together so a wider space reads as a single, cohesive window. Combining units lets you balance ventilation, natural light, and views while matching your home’s proportions and architectural style.
Combine three units to span a wider space that a single window can’t cover on its own.
Choose operable ends or all-operable units to direct fresh air into the room.
A larger combined glass area brings more daylight deeper into the room.
Symmetrical, coordinated units create a clean, architectural appearance.
Each configuration combines three individual window units into one larger opening. The diagrams below show which sections are operable and which are fixed, left to right.
Operable single-hung windows on each side with a fixed picture window in the center — ventilation from both sides paired with a large, unobstructed central view.
Hardware: The operable single-hung units use our verified Pull-Tight Cam Lock hardware. The center picture window is fixed and has no operating hardware.
Three single-hung units combined across one larger opening. Open any combination of the sashes for flexible ventilation — the sections don’t all have to be opened at once.
Hardware: Each single-hung unit uses our verified Pull-Tight Cam Lock hardware. You can operate any combination of the three sashes independently.
Operable casement windows on each side with a fixed picture window in the center — side ventilation combined with an unobstructed central view and a clean architectural profile.
Hardware: Casement units operate with a fold-away crank and lever lock — not a Pull-Tight Cam Lock. Specific casement hardware finishes are confirmed during your measurement. The center picture window is fixed.
Three casement units combined across one larger opening for multiple operable sections and a coordinated, contemporary look.
Hardware: Each casement unit uses a fold-away crank operator and lever lock — not a Pull-Tight Cam Lock. Casement hardware finish availability is confirmed at your measurement.
Available configurations depend on the size and conditions of the opening. American Remodeling’s measure team confirms final dimensions and product configuration before ordering.

It is three individual window units — such as single hung, picture, or casement windows — joined (mulled) together to fill one larger opening as a single, coordinated configuration.
A 3-Lite Slider is one sliding-window product with a fixed center panel and two sliding end panels. A three-unit combination joins three separate window units — which can be single hung, picture, or casement — into one larger opening, so you can mix different operating styles.
Yes. A common configuration places operable single-hung windows on each side of a fixed picture window, giving you ventilation from both sides and a large central view.
Yes. Operable casement windows on each side of a fixed center picture window provide side ventilation with an unobstructed central view.
Yes. Triple single-hung and triple casement configurations use three operable units. You can open any combination of the sections — they do not all have to be opened at once.
Available configurations depend on the size and conditions of the opening, individual unit sizing, structural conditions, and manufacturer sizing limitations. Our measure team confirms final dimensions and product configuration before ordering.
