What are the most common window types?

Whether you are planning to install new windows or replacement windows, you need to be familiar with the most common window types. Apart from their aesthetic features, windows also provide functional purposes, which include the provision of ventilation and access to natural light.

It is good to know that windows have different structural designs and operations. Some windows are perfect for broad views while some are best suited for ensuring massive airflow into the home. Regardless, the following are the most common window types you can get from windows and doors companies:

1. Awning Windows

Awning windows are crank-operated windows that open outward pivot from the top of the windows sash. They are usually installed alongside large picture windows. They are not suitable for high-traffic locations like walkways. Awning windows are good for improving the energy efficiency of the home.

2. Casement Windows

Casement windows are similar to awning windows but they open outward pivot from the side hinges. They let in a massive amount of light and ventilation because they can be opened wide. There are usually seals installed around the windows to boost their energy efficiency. They offer enhanced energy performance when closed and locked.

3. Single-hung and Double-hung Windows

Both single-hung and double-hung windows are very common. The only difference between them is that single-hung windows come with only one movable lower sash and a fixed upper sash. Meanwhile, double-hung windows have two movable sashes with the upper sash sliding down.

Double-hung windows offer better ventilation than single-hung windows to ensure more airflow. The exterior of double-hung windows can be cleaned inside and out without using a ladder.

4. Picture Windows

Picture windows are usually made up of large glass and they are best suited for areas that do not need airflow. They provide an unhindered view and sunlight into the home. They are static and less susceptible to air leakage, meaning that they are energy-efficient.

5. Bay Windows

Bay windows are used to create angles and projections beyond the walls of the building structure. Most bay windows usually have side windows that can be opened for ventilation. They are usually found in the kitchen and family rooms.

6. Slider Windows

This type of windows slides open sideways. They provide an unhindered view and lots of light into the home. Sliding windows are best used as egress windows in the basement. They are simple and do not have any mechanism apart from a lock.


The most common window types have been discussed above. When planning a window replacement project, ask your windows and doors company for the types you need for your home to enhance your home aesthetics and boost energy efficiency.
