Arched windows — sometimes called half-moon or curved windows — add a distinctive architectural detail that few other window styles can match. We design and install custom arched windows for Calgary homes, from a single accent piece to a full arch-top combination.
Arched windows use a curved top instead of a standard square or rectangular frame, and they're most often installed as a fixed accent above a door, entryway, or another window. As an official Jeld-Wen dealer, we build arched windows to your exact opening, whether that's a full radius arch, a half-round, or a custom curve. Because most arched windows are fixed rather than operable, installation is usually straightforward, and the result is a feature that changes the whole look of a facade. Every estimate is free, and every installation is backed by a manufacturer warranty.
An arched window is one of the fastest ways to give a home more architectural character, whether it’s a small accent above a door or a full arch-top combination window. It’s the kind of detail that sets a home apart on the street and often becomes a focal point of the whole facade.
Because arched windows are typically installed as an addition above or alongside an existing window, they add extra glass area and let more daylight into a room. Entryways, stairwells, and living rooms with high ceilings are common places where an arched window makes a real difference in brightness.
Arched windows are usually combined with a casement, picture, or fixed window below, so you get the curved accent without giving up ventilation or function. This flexibility means an arched window can be added to most home styles, not just historic or heritage homes.
Since most arched windows are fixed rather than operable, there’s no sash or hardware that can wear out or develop gaps over time. A properly sealed, Energy Star rated fixed arch window is one of the tightest-sealing options available, which helps limit heat loss through the curved section.
A complete half-circle top (180-degrees), often used above entry doors or as a standalone accent window. It’s the most classic arched window shape and works well on both traditional and modern facades.
A shallower, elongated curve — sometimes called a half-moon window — that adds a softer architectural detail without the height of a full radius arch. It’s a good option when ceiling height or window placement is limited.
A pointed, elongated curve that gives a home a more formal or traditional character. It suits homes with steeper rooflines or existing architectural detailing that calls for a sharper arch.
An arched window installed directly above a casement, picture, or fixed window, so the two work together as one unit. This is one of the most popular configurations because it adds the arch’s character without sacrificing the ventilation of the window below.
For openings that don’t match a standard arch shape, we can build a custom curve to fit your exact specifications. This is common in renovations or additions where the arch needs to match an existing architectural feature.
Custom shapes like arched windows require precise measurement and manufacturing, and that’s exactly where experience matters most.
With more than 30 years of combined experience, our team has measured and installed custom window shapes, including arched windows, across Calgary homes of every style.
We’ve installed more than 5,000 windows across Calgary and surrounding communities, including custom and specialty shapes like arched windows.
You’ll work directly with the owners of Sunbusters from your first measurement to final installation — no commissioned sales reps, no middlemen.
Most arched windows are fixed, meaning the curved section doesn’t open, since the shape makes a smooth-operating sash difficult to build. They’re typically installed above or alongside an operable window like a casement, so you still get ventilation from the window below the arch.
In many cases, yes, an arched window can be added above an existing door or window opening as part of a larger renovation, though it does involve more structural work than a straightforward window replacement. We assess your specific opening during a free estimate to confirm what’s possible.
A full radius arch is a complete half-circle, typically used above entry doors or as a standalone accent. A half-round or eyebrow arch is a shallower, more elongated curve, often chosen when there’s less vertical space available. Both are built to your specific opening rather than a fixed standard size.
Not significantly. Since most arched windows are fixed with no moving hardware, there’s actually less to maintain than an operable window: no crank, hinge, or lock to service. Cleaning is the main upkeep, and the curved shape doesn’t change that in any meaningful way.
We’re a trusted part of our customers’ lives. Their real experience reflect our commitment to compassionate care.
