Stack Unit Windows – Modern Design Meets Function
At Andes Windows & Doors, we provide Stack Unit Windows that elevate your space with modern design, abundant natural light, and uninterrupted views. These windows are ideal for homeowners, designers, and builders looking to create open, airy environments with a clean architectural aesthetic.
Stack units are perfect for both residential and commercial applications, offering the ability to expand any room with wide glass panels while maintaining excellent energy efficiency and structural strength.
Overview
Whether you’re watching the sun rise in the morning or set in the evening, patio windows provide the perfect view of the landscape that sits just beyond your backyard.
That’s why finding the right patio sliding doors for your home is so important; you need to experience and connect with the vistas of your region.
Art Direction
Whether you place your dining room table near these patio windows or have your favorite chair positioned so that you can enjoy the relaxing views, there’s no question that patio sliding doors provide an escape while remaining within the comforts of your own home.
What Are Stack Unit Windows?
Stack Unit Windows are made by joining multiple individual windows—often fixed picture windows—into one seamless configuration. This stacking technique allows for expansive glass walls, large vertical or horizontal sections, and custom arrangements that align with your architectural goals.
The units may include fixed panes only or integrate operable windows like casement or awning styles, providing both style and functionality. Their ability to be customized makes them an excellent solution for everything from panoramic living room views to bold commercial storefronts.

At Andes Windows & Doors, we help you design your stack units around your space and vision:
Glass Options: Clear, Low-E, obscured, laminated, or tinted
Operable Additions: Mix in casement or awning windows for airflow
Grids: From no-grid modern looks to colonial divided-lite patterns
Interior Finishes: Match your décor with woodgrain or smooth interior options
