Frequently Asked Questions

What are half moon windows and where are they commonly used?

Half moon windows—also known as semicircle or arch windows—feature a curved top and flat bottom. They're typically fixed and installed above entry doors or large rectangular windows to add a design accent and invite more light. In Toronto homes, they're often used in foyers, staircases, or as decorative elements in vaulted ceilings.

What are quarter moon windows and how do they complement home design?

Quarter moon windows are one-quarter of a full circle, often used in pairs or with half moon windows for a balanced, symmetrical look. They fit neatly into corners or above specialty windows, adding elegance and architectural interest. Their curved shape softens sharp design lines, making them popular in both traditional and modern builds.

How do quarter moon windows improve natural light in Toronto homes?

Quarter moon windows bring in light where it's usually lacking—above doors, staircases, or tucked into rooflines. Their unique shape helps spread light across a space while enhancing curb appeal. In darker Toronto homes or older builds, even a small curved window can make a big impact on brightness and mood.

Why choose Window Force for custom half moon windows?

We offer custom sizes, color options, and frame finishes, ensuring the unit matches your project perfectly.

What should homeowners consider before ordering specialty shaped windows?

Precision is everything. Double-check sizing, especially if fitting into an arched opening. Make sure the frame material matches the rest of your windows for consistency. And don't forget installation—curved frames require skilled fitting and sealing. Choose a supplier like Window Force that supports both product and installation guidance.
