Bold Architecture. Built for Performance.
Curtain wall systems are the hallmark of modern commercial design transforming building exteriors into sleek, glass-dominant façades while providing high-performance weather resistance, thermal insulation, and daylighting. At Centennial Glass, we specialize in the engineering, installation, and replacement of commercial curtain wall systems across Ottawa and the Valley.
With over 55 years of glazing experience, our team delivers custom curtain wall solutions that combine visual impact with airtight, watertight performance—tailored to meet your project’s structural, environmental, and energy goals.
Designing a large commercial façade or upgrading an outdated envelope?

What Is a Curtain Wall System?
A curtain wall is a non-load-bearing exterior wall made of lightweight aluminum framing and glass, attached to the structure of a building. It is designed to:
- Resist wind and weather while allowing natural light in
- Maximize thermal and acoustic performance
- Reduce air and water infiltration
- Provide a seamless, modern look for multi-storey buildings
Curtain wall systems are typically used in:
- Office towers and high-rise commercial buildings
- Government buildings and public-sector institutions
- Educational campuses and healthcare facilities
- Museums, performing arts centers, and airports
