What Are Bay & Bow Windows?
There are many different types of bay windows but the most popular combination is a large stationary (picture) window in the centre and two operable casement windows that flank it on either side. The angled window unit provides extra seating area for a unique design feature. The picture window feature allows more natural light to penetrate the room while the operating windows provide extra ventilation.
Other services: casement windows, sliding windows, hung windows, fixed and picture, hopper, custom shape windows.
Ecoline bow windows combine four or five casement windows mulled into one continuous unit. They are designed to arch out with a cantilevered construction to provide a window seating area and wide views from every angle. The units can combine stationary and operable casement windows for extra ventilation.

Double & Triple Bay Windows
Glass panes are the largest area of any Bay window and the most vulnerable to heat loss and gain. To provide adequate thermal performance for harsh prairie climates, a minimum of 2 panes are required. Traditional 7/8ā³ double glazing options are used and can accommodate 1-1/4ā³ for all Bay windows.
In areas with prolonged low winter temperatures, triple pane windows will perform best. Ecoline triple glass packages qualify for high energy-rating standards with 1-3/8ā³ and 1-1/4ā³ options available. Can be used in combination with gas injection and/or LoE glass coatings but are not necessary.

F.A.Q.
What are the most popular Bay window types?
Ecoline offers you the two most popular window types – Bay and Bow. Bay windows are made of a picture window in the center and two operable casement units, while Bow windows combine four or five windows into one continuous unit.
What are the best Bay replacement windows?
Ecoline experts consider the triple-pane Bay replacement windows with LoE and Argon as a go-to option when it comes to overall performance.
What is the difference between a Bow and a Bay window?
The main difference lies in the number of units. While the Bay replacement window is made of 1 picture and 2 casement unis, the Bow window comprises 4-5 units.
How much does it cost to add a Bay window?
Since the Bay window is made of several units (a picture window + 2 casement windows), it will usually cost significantly more than regular windows. To get a precise quote, please contact the Ecoline project consultant.
Which rooms would look best with Bay windows?
Usually, Bay Windows are installed in living rooms since these units are perfect for letting a lot of natural light into your area and providing excellent ventilation.
What is the best frame material for Bay replacement windows?
At Ecoline, we consider vinyl replacement Bay windows as the best option.
