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.
