What Are Sliding Windows

Sliding windows are designed to allow superb ventilation from floor to ceiling, tilt in or lift out for easy cleaning, and with few moving parts, are one of the best low-maintenance styles available.

Other services: casement windows, fixed and picture, hopper, custom shape windows.

Types Of Windows


Single Tilt

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

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 Lift Out

As the name implies, double lift out sliding windows include two operable sashes. They slide along a track horizontally and open wide for maximum ventilation. Both lift out when cleaning is required.


Vertical sliding windows are called Hung. These units are very versatile and match most home styles. Ecoline’s vinyl hung replacement windows come in many shapes, sizes and colours.

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.

Find out more benefits of triple pane windows over double pane


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.

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 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.

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.

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