Folding Sliding Doors Canada (FSDC) is marking its 20th anniversary with the launch of a major addition to its product lineup: the FD7550S Thermally Broken Aluminum Multi-Slide Door System. Built on two decades of engineering expertise, this new system expands the possibilities for homeowners, builders, and commercial clients looking for modern design, smooth operation, and reliable performance across all North American climates.
FSDC has long been recognized for its industry-leading folding sliding door systems, and the multi-slide series now offers a complementary option designed for projects where stacking panels, expansive glass spans, and sleek contemporary lines are a priority.
A Seamless New Way to Open Up Your Space
The FD7550S Multi-Slide Door System is engineered for uninterrupted views and effortless transitions between indoor and outdoor spaces. Panels glide smoothly along a track and stack neatly out of the way, allowing you to:
- Create a full, unobstructed opening
- Maximize natural light
- Improve airflow and liveability
- Avoid the need for interior or exterior swing clearance
From residential patios and pool areas to commercial dining spaces, the multi-slide system offers an inviting connection to the outdoors without impacting functional space.
Tested, Certified, and Built for North American Climates
Performance and reliability are key pillars of the FD7550S design. The system is tested and certified to NAFS 2022 and CSA A440S1-25 standards by both QAI and Intertek laboratories. This ensures dependable results in:
- Air tightness
- Water penetration resistance
- Structural performance
- Thermal efficiency
It’s a 70mm thermally broken aluminum frame with a 28mm polyamide break that provides enhanced insulation, making it suitable for everything from coastal weather conditions to cold Canadian winters. Depending on configuration, U-values range from 1.21 to 1.80 W/m²K.
Multi-Slide vs. Folding Sliding Doors: How Do They Compare?
FSDC now offers two premium door systems engineered for indoor–outdoor living. Both deliver durability and quality manufacturing, but they serve different design goals.
How Multi-Slide Doors Differ
- Panels slide and stack linearly, creating a sleek, modern appearance.
- Ideal for long, wide openings with up to 20 panels available.
- No swing space required, making it suitable for tight layouts and high-traffic areas.
- Often preferred for commercial spaces due to smooth operation and streamlined aesthetic.
Where Folding Sliding Doors Excel
- Panels fold and stack to the side, opening the entire width in one movement.
- Offers everyday convenience with available active swing doors.
- Provides a more architectural or traditional look, depending on configuration.
- Creates a dramatic open-wall effect with fewer panels.
Many projects incorporate both, choosing multi-slide for long linear openings and folding systems for primary access or more structured architectural styles.
Industry-Leading Features of the FD7550S
Key features of the new multi-slide system include:
- Up to 20-panel configurations (ten each direction)
- Concealed multipoint locking system for security and simplicity
