Types of Windows

If you are experiencing any of the problems listed above, it may be time to get new windows. But the question is, which windows are right for you? With so many to choose from, it can be difficult to make a decision.

In this section, we will review the windows that are available so that you can make an educated choice.

Awning windows lift out from the bottom of a window to open at a 45-degree angle. The angle works to protect the home from rain and other elements. They also provide the ultimate in airflow making them ideal for kitchens, bathrooms and other areas that are prone to mold and mildew due to humidity.
To ensure your awning windows are doing all they can to boost your energy efficiency while protecting your household, be sure to look for features like multi-point locking systems and fusion welded corners that will keep out water and air. A multi-chamber construction is also recommended for its ability to increase thermal efficiency, while providing insulation, durability and noise minimalization.

Casement windows have a crank that allows them to open to a 90-degree angle. The opening provides optimal airflow within interiors.
Triple sealed panes and an optimal number of internal air chambers will ensure the ultimate in energy efficiency while keeping the elements out. An advanced locking system is also recommended for providing safety and security.
casement window

Double slider windows have two panes that move along a track. They open on either side to overlap each other to let air in. They can also fully open into the house to make cleaning easy and provide ultimate air flow. Their ability to provide ventilation makes them ideal for humidity hotspots such as kitchens and bathrooms.

Sliding windows with optimal internal air chambers will be ideal for providing thermal efficiency and insulation.
single and double slider window

Double hung windows feature one pane under another. Both panes can be moved up or down on the track to allow the window to open from the top or bottom.

Double hung windows are a popular design and a favorite among homeowners. Elegant updates in recent years have made them a trendy option for homeowners. A multi-chamber construction will further provide structural integrity.

Because the windows have a flat exterior, they are ideal for patios, walkways and other areas that may be impeded by windows that open outwards.

Single slider windows are a variation of double slider windows. Like the double slider variety, they open by sliding along their track, however, they open from one side only. If you like sliding windows, they are a more affordable option.

When low-E or low emissivity, glass is used, it results in the emission of low levels of radiant thermal energy. When combined with a krypton gas insulation, these windows can achieve optimal energy ratings.

single slider window

Single hung windows vary from double hung windows in that only the bottom pane will move when opening the window. They provide a classic style that works well in most interiors.

For the ultimate in energy efficiency, look for windows with a multi-chamber construction and an Energy Star rating.

End vent slider windows have a fixed pane in the middle and two sliding windows on either side that move inward toward the center open. They are a good alternative to double slider windows that are better suited to smaller spaces. They also make a good option for those looking for a cost-effective alternative to casement windows.

In most cases, the middle pane will release to open inward to make for easy cleaning while letting in some much-needed fresh air.

Picture windows are stationary windows that don’t open. Rather, they are meant to let light in, provide a view and work as a decorative element within the home. They are often paired with other types of windows like fixed casement, double hung or side slider.
