Seamless Transitions with Multi-Slide Doors
Multi-Slide Aluminum Door Systems are designed to expand your living and entertaining areas with ease. With wide, clean openings and smooth operation, they create a natural connection between indoor comfort and outdoor space. In both residential and commercial settings, they introduce fresh air, natural light, and a more open sense of living.
Enjoy outdoor access without compromising floor space. Multi-slide doors stack neatly behind one another, allowing a full, unobstructed opening to your patio, poolside, or garden retreat. Built for both appearance and performance, these systems offer reliable operation, versatile layout options, and excellent energy efficiency thanks to their thermally broken aluminum construction.
The FD7550S series goes a step further. Independently tested and certified to NAFS 2022 and CSA A440S1-25 standards by QAI and Intertek laboratories, it delivers verified performance in air tightness, weather resistance, and structural strength. This ensures dependable operation in all kinds of North American climates.
The FD7550S Multi-Slide unit is available in standard colours like black or bone white, as well as anodized finishes including clear, dark bronze, and black. For projects requiring something unique, custom powder-coated and anodized options, such as silver or gold, are available.
For commercial environments, multi-slide doors create an inviting open-air setting, allowing guests and staff to move freely between indoor and outdoor areas. Their contemporary lines, certified durability, and proven performance make them a strong choice for hospitality, retail, and workplace settings across North America.
