Awning Windows

As they are hinged at the top to open outward, awning windows are designed to provide maximum ventilation while protecting your home from rain, sleet, and snow. This gives you the option of keeping your windows open no matter what the weather is outside. You can install these hinged windows in any room in your home where you want the maximum air flow while preserving the view of the outdoors.

At Atlant Windows, our awning replacement windows Toronto can be equipped with multi-point locking systems, located on the interior of your window on the left and right sides. The screens are situated on the inside of the window for enhanced security as well as to keep bugs, dirt, and debris from entering your home.

Casement Windows

Casement windows, which are sometimes referred to as French casement windows, are hinged to the side and open outward via the use of a crank mechanism. One of the main advantages of casement windows is that they can swing open to the left or the right. The sleek design of casement windows allows them to lay flush to the window frame, so they will not interfere with your window treatments.

As they have the capacity to crank fully open, casement windows are an outstanding source of both fresh air and natural light for any room of your home. They operate effortlessly with a single hand crank, so they can be installed in hard to reach areas such as above the kitchen or bathroom sinks or countertops.

Double-Hung Windows

As our most popular choice for windows replacement Toronto, double hung windows are not only an outstanding source of ventilation, they are versatile, secure, and easy to clean.

They will work nicely in almost any room of your home, as they require little to no maintenance or upkeep.

Double hung vinyl windows Toronto are designed with two operable sashes that tilt for easy cleaning. Depending on the window size, they can be equipped with one or two interior locks. You will not have to worry about safety and security due to the fact that the staggered ventilation latches limit the amount that you can raise or lower each window sash.

Double Slider Windows

As they can be designed in either 2 or 3 section sliders for wider spaces, slider windows can drastically alter the style and function of the current opening of your windows. As with their double hung counterparts, the sashes on these windows can be removed with ease for cleaning. As a bonus, sliding windows have very few moving parts, so they will require less maintenance and upkeep than most other window types.

Double slider windows are extremely easy to operate and can provide outstanding air flow to any room of your home. Moreover, they can be equipped with a screen to prevent bugs and flies from entering your home.

Hung Windows

Single hung windows are those that open up and down (or vertically). Only one sash is movable while the other is stationary (or fixed). They can be designed to tilt inward for easy cleaning. They are a less expensive option of double hung windows.

One sash will vertically open and close and is equipped with a half screen to prevent bugs, dirt, and debris from entering your home while allowing for fresh air and sunlight. At Atlant Windows, our single hung windows are designed of durable 100% PVC fusion-welded sashes and frames to prevent drafts, which can help lower your heating and cooling bills.

Fixed windows are ideal for those who prefer a great deal of sunlight. They are designed of non-operable glass panes, so they are not ideal for those areas that require ventilation. However, they can be paired with other styles of windows, such as casement windows, if ventilation is a must.

Fixed windows provide an unobstructed view of the great outdoors and are ideal for living rooms, home office spaces, and family rooms, as they can make any room seem larger and brighter.
