Bay Windows

Bay windows are a perfect choice for homeowners looking to boost functionality and bring a touch of beauty to everyday life. At HTR Windows and Doors, we offer professional bay window replacement services across Canada:

  • Multi-chamber weather protection — our bay windows feature layered frames and thermal insulation that keep out drafts and leaks all year round;
  • UV-resistant Low-E glass — double and triple glazing with Low-E coating helps block harmful UV rays while still letting in plenty of natural light;
  • Excellent ventilation — a wide 180-degree range of motion and water-resistant sills let fresh air in, whether rain or shine.

We install and replace bay windows made right here in Canada. With 28 frame colour options, specialty hardware, and custom features to choose from, you’ll get a renovation solution that makes a real difference in how your home looks and feels.

What Is The Difference Between Bay and Bow Windows?

Bay and bow windows are similar in some ways, which is why they’re often mixed up, but there are some key differences to keep in mind:

  • Bay windows are typically smaller and made up of 3 windows with sharper, angular lines;
  • Bow windows are usually larger, made up of 4-6 windows that create a gentle, outward curve.

Both options offer beautiful panoramic views and allow natural light to fill your home. Not sure which one’s the right fit for your home? Contact us to schedule a free in-home consultation with one of our experienced window installers.

Thanks, HTR, for the incredible window replacement. We opted for complete window replacement (17 different windows) and did not regret it. They were on time, and the service was top-quality. From the sales consultation up to technical moments and installation, we got all the info we needed to be on the same page. All these for a fair price! I can’t thank them enough, but I definitely will recommend them to all my neighbours.
