Northline Windows & Doors

Fixed windows are probably the simplest windows in the house. They don’t open, they don’t crank, and they don’t slide. They’re there to give you glass—and lots of it.
That simplicity is exactly what makes them useful.
Think about a living room overlooking the backyard, a tall stairwell that always feels a little dark, or an opening where you already have plenty of ventilation from another window. Sometimes adding another handle, screen and operating sash just gets in the way of what you actually want: more natural light and a better view.
Fixed windows are especially good at that because there are no moving parts competing for space. The result can be a cleaner-looking window with a larger uninterrupted area of glass.

But that doesn't mean every big opening should automatically become a fixed window.
The question we usually come back to is: do you need this window to open? If the answer is yes, an operable style such as a casement or awning window will probably make more sense. If the answer is no, paying for hardware and an operating sash you rarely use might not add much value.
And you don't always have to choose one or the other.
Some of the nicest window configurations combine a larger fixed section with operable windows beside it. You keep the open view and natural light through the centre while still being able to let some fresh air in when the weather cooperates. On an Ottawa spring day after months of winter, you'll probably be glad you kept that option.

Northline's fixed windows are custom-made for each opening and manufactured in Ontario, with different glass and configuration options depending on the room and what you're trying to accomplish.
On this page, we'll look at where fixed windows make the most sense, how they compare with operable windows, and what to consider before deciding where they belong in your home.
Fixed Window Basics
A fixed window doesn't need to be the star of every room. In fact, they're most useful when they're placed somewhere you want the benefits of a window without really needing it to open.
That could mean creating a bigger view, bringing daylight into an awkward part of the house or pairing a large piece of glass with smaller windows that handle the ventilation.
Living Rooms, Stairwells & Hard-to-Reach Spaces
If your living room looks out over the backyard, a garden or even just a nice tree-lined street, you probably don't want a bunch of hardware sitting in the middle of it.
Fixed windows can create a larger, cleaner area of glass with fewer visual interruptions. They're especially useful in larger openings where natural light and the view matter more than ventilation.
They can also solve a completely different problem higher in the house. A fixed window halfway up a staircase, on a tall wall or in a vaulted space can bring daylight into an area where an opening window wouldn't be particularly useful anyway.

Nobody wants to stretch over a railing every time they want to open a window they realistically never needed to open in the first place.
Combine Fixed Glass With Operable Windows
Fixed windows don't always need to work alone.
One of their most practical uses is as the larger section of a combination window, with casement windows or awning windows positioned beside, above or below it.
The fixed portion provides the larger area of uninterrupted glass while the smaller operating windows handle ventilation.
It's a nice middle ground for homeowners who look at a big wall and think, “I want more glass, but I still want to open something.”
Are Fixed Windows Energy Efficient?
Because a fixed window doesn't need hinges, cranks or an opening sash, there are fewer moving components involved in the design.
But that doesn't mean every fixed window automatically has the same energy performance. The frame, glass package, spacer system, seals and installation still contribute to how the complete window performs.
You can also choose different glass configurations depending on what you're trying to accomplish. For a large fixed section where thermal performance is particularly important, comparing double and triple pane glass can be worthwhile.
The lack of operating hardware is an advantage, but the complete window still determines its performance.
Fixed Windows, Picture Windows & Larger Glass Designs
You'll sometimes hear “fixed window” and “picture window” used almost interchangeably because neither is designed to open.
The basic idea is similar: glass without everyday operation. Depending on the window system and configuration, however, fixed sections can be incorporated into larger combinations alongside operable windows, while a picture window is typically chosen specifically to emphasize a larger uninterrupted view.
Either way, you're choosing to dedicate that part of the opening to glass rather than ventilation.
Colours, Grilles & Glass Options
Removing the operating hardware also gives the design a cleaner starting point.
White frames can keep a fixed window traditional and understated, while black, charcoal and darker exterior colours can make a larger glass opening feel considerably more contemporary. Grilles can introduce architectural detail, or you can leave the glass uninterrupted when the view is the priority.

Privacy glass can also make sense in certain locations where you want daylight without such a clear view through the window.

Fixed doesn't have to mean plain. It simply means the window's job is light, glass and the view rather than opening and closing.
Fixed vs Operable
The biggest difference is obvious: one opens and one doesn't.
But when you're planning a window replacement, that single difference affects quite a bit — from ventilation and the amount of visible glass to how much hardware you have to operate and maintain.

Fixed Windows Prioritize Glass & Simplicity
Fixed windows are designed around the glass rather than the mechanics required to open them.
There's no crank to reach for, no screen sitting between you and the outdoors and no operating hardware to use every day. That can make them particularly appealing for larger openings where the view itself is part of the room.
There are fewer moving components to think about as well. The glass, frame and seals still need to remain in good condition, but there are no hinges, cranks or locks being operated throughout the year.
Operable Windows Give You Fresh Air
There is one feature no fixed-window design can replace: ventilation.
Casement, awning, sliding and hung windows allow you to bring fresh air into the room when you want it. That can be particularly valuable in bedrooms, kitchens and spaces where opening a window is part of how you actually use the room.

So before choosing fixed, ask yourself a very practical question:
Do we actually open this window?
If the answer is yes, keeping some form of operation probably makes sense.
You Don't Have to Choose Just One
A large fixed window can sit between two operable windows. An awning can go underneath a fixed section. Different configurations can give you plenty of uninterrupted glass while preserving ventilation where it's useful.
For many Ottawa homes, that's more practical than making every section open simply because it can.
Let the room make the decision. If light and the view are the priority, fixed glass may make perfect sense. If fresh air matters, keep an operable section. And when you want both, design the opening to give you both.
