Ribbon Windows Ottawa | Commercial Window Systems

Detail That Defines Your Design

Grills, also known as muntins, simulated divided lites (SDLs), or internal dividers, add architectural character and visual structure to your commercial windows. At Centennial Glass, we install, repair, and match window grills for sealed units, storefronts, ribbon windows, and more—enhancing your building’s design without compromising performance.

Whether you’re recreating a heritage look, coordinating with adjacent buildings, or simply adding definition to your façade, we help you select and integrate grill designs that match your aesthetic, frame system, and thermal goals.

What Are Ribbon Windows?

Ribbon windows also called strip windows or band windows are a series of adjacent units installed side by side to form a long, narrow band of glass. They’re often used to:

Maximize natural light across large interior spaces
Maintain horizontal alignment in modern façades
Break up monolithic cladding with glazing accents
Provide continuous visibility and daylight without full-height glass

Centennial customizes ribbon window systems using high-performance sealed units (IGUs), Low-E coatings, tinted or reflective glass, and internal grills for decorative or architectural alignment.

Ideal Applications for Ribbon Windows

Ribbon windows are commonly used in:

Educational institutions and school boards
Office buildings and government campuses
Hospitals and medical clinics
Industrial and warehouse buildings
Mid-rise residential or mixed-use developments

They’re especially effective in long floor plans where natural light must be spread evenly, or where a horizontal design language supports the building’s aesthetic.
