A triangle window is made to fit sloped, angled, or triangular spaces where regular
rectangular windows do not work. Most triangle windows do not open and are often used in
gables, cabins, A-frame houses, vaulted rooms, or as part of larger window designs.
At Ecoline, we make custom triangle replacement windows that fit your home’s size, roof
shape, glass needs, and colour.

Triangular-shaped windows for any opening size
The price of triangular windows depends on their width, height, angle, glass type, frame
colour, and installation. Larger gable and A-frame windows are priced separately because each
requires custom measurements.
On average, a triangular-shaped window usually costs between $1,300 and $1,600. Triple-pane
models are about 15% more expensive than double-pane units. The final price depends on
the shape, size, glass options, and the condition of your current window opening.

Most triangle windows do not open because their angled shape works best for fixed designs. If you need ventilation, you can add casement or awning windows next to or below the triangle window.
You often see triangle windows in gables, cabins, A-frame houses, lofts, rooms with vaulted ceilings, and custom window walls.
Yes, you can order custom triangle windows with double-pane or triple-pane glass. The choice depends on the window’s size, design, and how much energy efficiency you want.
