Modern Design. Full-Daylight Functionality.
Window wall systems allow architects and builders to create expansive, light-filled building façades—without the complexity of curtain wall systems. At Centennial Glass, we specialize in the supply, installation, and replacement of commercial window wall systems that deliver the modern look of full-glass architecture, combined with energy efficiency, noise reduction, and structural performance.
Whether you’re building a high-rise condominium, an office tower, or a mixed-use development, our window wall solutions are designed to fit seamlessly into floor slabs and structural openings—giving you the bold look of glass with practical benefits.
Designing a large-scale residential or commercial façade?
What Is a Window Wall System?
Unlike curtain walls, which are hung from the exterior of a structure, window wall systems are installed between floor slabs and supported by the building’s concrete or steel structure. This makes them ideal for:
- Condos and high-rise residential buildings
- Office towers and modern mixed-use buildings
- Institutional facilities and educational campuses
Centennial customizes each system based on your building layout, thermal performance requirements, and visual design goals.
Features of our window wall systems:
- High-performance sealed units (double or triple-pane)
- Thermally broken aluminum frames
- Integration with opaque spandrel panels or slab covers
- Noise reduction (STC-rated) and energy savings (Low-E & gas-filled)
- Optional operable vents or windows
- Custom tints, finishes, and internal grills
