Single tilt slider windows operate along a track and allow the windows to move side to side. They include one stationary and one operable window sash for maximum glass area and exceptional ventilation. The windows tilt inward for easy cleaning.

Double Tilt

Double tilt windows are designed with two operable sashes. They slide along a track horizontally and can be used together or independently for maximum ventilation. The tilt feature is available on both sashes for simple cleaning.

End vent sliding windows are often used for window openings wider than 74 inches. They include two venting sashes and a low, fixed centre sash. These offer a large glass area for unobstructed views and superior ventilation capabilities.

Single Lift Out

Single lift out windows move side to side along a track and include one stationary and one operable window sash. They offer exceptional energy efficiency while allowing the maximum amount of light and air into the room. The sashes lift out for effortless cleaning.

Double & Triple Pane

Glass panes are the largest area of any window and the most vulnerable to heat loss and gain. To provide adequate thermal performance and save up your money on energy bills, a minimum of 2 panes are required. Traditional 7/8″ double glazing options are used and can accommodate 1-1/4″ for all sliding windows

In areas with a harsh climate, triple pane sliding windows can be especially profitable. Ecoline triple glass packages qualify for high energy-rating standards with 1-3/8″ and 1-1/4″ options available. It can be used in combination with gas injection and/or LoE glass coatings but are not necessary.

What are the best sliding windows?

At Ecoline, we consider the triple pane sliding windows that go with LoE and Argon as an optimal configuration for energy efficiency and daily usage.

Awning vs Sliding Windows: What is Better?

Both window styles are great. While sliders are super easy to operate, do not need much space and are easy to clean, awning windows are great for hard-to-reach areas and provide good ventilation.

Casement vs Sliding Windows

Casement windows are superb when energy efficiency is concerned and can be placed strategically so that even a 2 to 3-inch opening would bring fresh air inside. Sliders, on the other hand, provide an unobstructed view outside, bringing more natural light to your space.

Single Hung vs Sliding Windows

Well, hung windows are usually less energy-efficient, and what is more critical, have a check rail, the horizontal bar in the middle where the two sashes meet and obstruct the view outside. It is no problem when you choose sliders.

Sliding Windows vs Double Hung: Cost

Sliders are usually more expensive since they come in a bigger size and have more glass area.
