Arched curtains for half-moon and arch windows

Half-moon, arched, and curved windows add unique architectural character to your home, but they pose a real challenge for window treatments. At Rideaux Nalia, we have the artisan expertise to craft custom solutions that respect your window's shape rather than hiding it. Pleated fans, arched curtains, draped sheers: every option is handmade.

We work with templates taken directly from your window to guarantee a perfect fit. For half-moons above entry doors, we create decorative fans in sheer or opaque fabric. For large arched windows in living rooms or stairwells, we craft curtains that follow the curve while offering functional opening.

Prestige residences in Sherbrooke, heritage homes across Estrie, and Magog chalets often feature specialty-shaped windows that require particular expertise. Our artisan couturière has the experience to work with these unique configurations. Every project begins with a consultation and hand sketches to visualize the result together before the first fabric cut.

The first question: does it need covering at all

An arched window is often an architectural feature. It is high, usually fixed, and its job is to bring in light. Plenty of arches are better left bare, and I say so during the consultation when that is my view.

The time to cover one is when it causes a real problem: direct sun bleaching a floor or a piece of furniture, excessive summer heat, or a bedroom where daylight arrives too early. If none of those apply, leaving the arch clear is often the better decision.

The solutions that genuinely exist

  • A fixed panel shaped to the arch, which handles light permanently and is not operated.
  • A curtain mounted below the arch, treating the rectangular part and leaving the arch free.
  • A custom pleated fan that follows the curve and folds back toward the centre.
  • Film or a glazing treatment, when ultraviolet is the only real issue.

The template, which is not a step to skip

An arched window is almost never a true half circle. In a house that has settled, the arch is asymmetric, and a panel cut to a theoretical radius leaves a visible gap on one side. So I take a cardboard template on site rather than working from measurements.

That is why an arch is measured in person. A straight-on photo to 873 200-4056 still lets me say what is realistic and rule out what is not.

The noblest shapes deserve craftsmanship to match.
