Window Aesthetics
Choosing the Right Look

When most Ottawa homeowners consider window replacement, their first thought is often energy efficiency. And while that’s undeniably important, especially in our extreme climate, the aesthetic value of new windows is just as impactful.

In this article:

Why aesthetics matter in window replacement

Windows are more than just openings to the outside world. They frame your views, affect how natural light enters your space, and play a major role in both curb appeal and interior design. Whether you're refreshing a tired-looking exterior or updating a dated interior, the right window style can elevate your home in ways that go far beyond insulation and glass.

Common window types for Ottawa homes

Ottawa homes range from charming century-old brick houses to sleek, modern infills, and the type of window you choose should reflect your home’s personality and design vision. Each window type offers a distinct visual character that helps define both exterior curb appeal and interior atmosphere.

Picture Windows

Picture windows are all about bold, uninterrupted beauty. These large, fixed panes act like a living portrait of the outdoors, allowing natural light to flood in while creating a striking visual centrepiece. Whether in a stairwell, a living room, or a vaulted space, they deliver a sense of openness and calm.

Casement Windows

With their sleek, uninterrupted panes and outward-opening design, casement windows deliver a crisp, contemporary look. Their vertical orientation and minimal framing help create a sense of height and openness, a perfect match for modern or transitional spaces that favour clean lines and expansive views.

Awning Windows

Awning windows offer a distinctive horizontal look with a top-hinged design that opens outward. Their compact shape makes them visually appealing above sinks, in bathrooms, or paired with larger fixed windows. They bring a clean, modern edge to any space while maintaining a low-profile charm that suits both contemporary and transitional home styles.

Double-Hung Windows

Rooted in tradition, double-hung windows bring symmetry and a classic charm that feels right at home in Ottawa’s heritage districts. Their balanced, vertical design complements older brick façades and adds timeless elegance to interior spaces, especially where historical authenticity matters.

Sliding Windows

Defined by their horizontal proportions and minimalist frame, sliding windows create a streamlined, modern aesthetic. They’re ideal for contemporary designs that emphasise long sightlines, low profiles, and understated elegance, perfect for open-concept layouts and lower-storey spaces.

Bay and Bow Windows

Architecturally striking, bay and bow windows add dramatic visual interest to any home. Their curved or angled projection from the wall draws the eye and creates a sense of grandeur, inside and out. These windows are ideal for front-facing rooms, where they can serve as focal points and frame picturesque views.

Frame colours and finishes

Window frame colour has become a defining feature in both interior and exterior design. In Ottawa, black and charcoal frames remain popular for modern renovations, offering contrast against white or neutral siding. These colours can give even a modest home a striking, modern look.

Inside, wood-look vinyl finishes or custom colour-matched interiors can tie your new windows in with existing trim, cabinetry, or flooring. With today’s manufacturing capabilities, you don’t have to choose between beauty and durability; you can have both.

Grilles, simulated divided lites, and mullions: creating the look of divided windows

Divided-lite windows have a timeless appeal, and today’s window designs offer multiple ways to achieve that classic look while meeting modern performance standards. Whether you’re restoring a heritage home or adding texture to a contemporary build, it’s helpful to understand how grilles, simulated divided lites, and mullions work and how they differ.

Grilles-between-glass (GBGs)

These decorative bars are sealed between two panes of insulated glass. They offer a clean, low-maintenance solution for achieving a traditional look without interfering with the window’s surface.

Simulated Divided Lites (SDLs)

SDLs use surface-applied bars on the outside (and sometimes inside) of the glass to mimic the look of older, true divided-lite windows. They’re often paired with a spacer between the panes to create the illusion of depth. SDLs are a modern answer to traditional mullioned windows, giving the same visual structure without sacrificing energy efficiency.

Mullions

Mullions are structural elements that physically separate individual window units installed side-by-side. In older window construction, mullions were often a hallmark of traditional multi-pane windows, forming the framework for true divided lights. Today, they’re used more sparingly but still provide architectural strength and visual rhythm in multi-unit installations.

A little-known window aesthetic insight

While only mullions divide separate window units, grilles and SDLs can replicate the same visual effect, adding character, rhythm, and balance. Even the thickness and layout of these elements can influence how a room feels, making windows appear larger, more elegant, or more structured depending on the design. Designers often use grille patterns to subtly guide the eye, balance proportions, and make windows feel like part of the architecture, even if most homeowners don’t consciously notice.

Glass customisation for privacy and style

Today’s glass options allow you to tailor both the function and feel of your windows:

Privacy glass

Frosted or textured glass options are ideal for bathrooms, basements, or side windows, letting light in and protecting your privacy.

Tinted or Low-E Glass

Adds style and improves energy efficiency, especially in sun-exposed rooms.

Decorative Inserts

Perfect for transoms, sidelites, or entryway windows, giving a touch of personality or elegance.

Creative window shapes and placement

Don’t be afraid to get creative. Adding a transom window above a standard window can increase light without sacrificing wall space or privacy. Consider arched, circular, or custom-shaped windows to highlight unique architectural elements or soften hard lines in modern homes.

These design decisions can also improve natural lighting, affect how a room feels, and highlight exterior features like gables, stonework, or entryways.

Ottawa design trends: blending new and old

From Westboro to the Glebe and into the suburbs, Ottawa’s residential design trends are diverse — and so are window choices.

In infill developments or newer subdivisions, dark frames and large, uncluttered windows create a sleek, minimalist look.

In heritage conservation districts, authenticity is key. Traditional grille patterns, historically accurate proportions, and classic finishes help homes blend seamlessly into their surroundings.

Matching the window style to your home’s architecture isn’t just about appearances; it can add resale value and ensure long-term satisfaction.

Balancing aesthetic appeal with practical performance

At the end of the day, your windows have to work just as well as they look. That’s where choosing the right product and installer makes all the difference.

Triple-glazed windows

Offer unmatched energy savings, but their slightly thicker frames need to be considered for design consistency.

Professional installation

Ensures that beauty doesn’t come at the cost of air or water leaks, or long-term performance.

Let form and function work together

Whether you’re planning a major renovation, building a home, or simply replacing a few ageing units, think of your windows as part of your home’s character, both inside and out.

A thoughtful approach to window aesthetics, backed by expert advice, can turn your window replacement into a transformation that combines performance, beauty, and style.
