Selecting the right basement windows can transform your basement from a dark, enclosed area into a bright, inviting living space. Bringing in natural light through thoughtfully selected basement window types helps create a more open and comfortable environment. This guide explores the most popular types of basement windows, each with unique benefits to suit various needs in basement living spaces, especially if you are looking to install or replace basement windows in Portland, OR.
Hopper windows are one of the most frequently used basement window types, popular for their space-efficient design and ease of use. These windows are installed high on basement walls and are typically wider than tall ones, providing natural light without taking up much wall space. The window is hinged at the bottom, allowing it to open inward from the top. This inward opening design secures hopper windows, as the locking mechanism is easy to reach.
Advantages:
Considerations: One disadvantage is that hopper windows may let rain or snow in when open, as their inward-tilting design leaves them vulnerable to outside elements. However, this may be less of a concern for basements, where window wells offer added protection.
Awning windows provide another practical option for basement spaces. These replacement windows are similar to hopper windows but open outward from a top hinge, creating a natural awning effect. This outward opening keeps rain and debris from entering the basement, even when the window is open, making them especially useful for areas with wetter climates, such as Portland, OR.
Advantages:
Considerations: Since awning windows open outward, they may not be ideal for basements with narrow window wells or those installed near walkways or patios, as the outward swing can interfere with these spaces.
Horizontal sliding windows, or sliders, are famous for basements with significant above-ground exposure. This window type typically features two panes, one sliding horizontally over the other. Slider windows are highly functional, providing easy operation and a comprehensive, unobstructed view of the outdoors. These windows are particularly well-suited for walkout basements.
Advantages:
Considerations: While slider windows are convenient and allow for easy airflow, there may be better choices for small window wells or completely below-ground basements, as a more significant portion of the window is typically exposed above ground.
Fixed or picture windows can maximize natural light in a basement, especially in areas where ventilation is not a priority. These non-operable windows provide a clear, expansive view, often making basement rooms feel more spacious. Since they are fixed, they can be larger than other operable windows, making them a popular choice for homeowners aiming to create a visually open atmosphere.
Advantages:
Considerations: Fixed windows do not open, so they do not contribute to ventilation. They are best used in basements where air circulation is managed by other means, such as ventilation systems or fans.
Double-hung windows are a versatile choice for basement windows, even though they are more traditionally used in main living spaces. These windows feature two operable sashes that slide up and down, allowing the window to open from the top or bottom. This dual-opening function allows for customized airflow, making it easier to control ventilation.
Advantages:
Considerations: Double-hung windows are most suitable for mostly or completely above-ground basements. They may not fit visually or functionally in window wells, so they are best installed in exposed basement walls.
Casement windows are often preferred for basements with higher walls and more above-ground exposure. They open outward on a side hinge operated by a hand crank. Casement windows provide maximum ventilation, as they open fully, and they are easy to secure with built-in locking mechanisms. Their tall, narrow design makes them stylish for areas with more sunlight and space.
Advantages:
Considerations: Casement windows could be better for fully below-ground basements, as narrow window wells can hinder their outward swing. However, they can be a stylish and functional choice for exposed or walkout basements.
Beyond style, material selection is also crucial when choosing basement windows, as basements often have higher humidity levels. Vinyl is generally the preferred material for basement windows in Portland, OR, because it is resistant to moisture, mold, and warping. Vinyl windows are durable, require minimal maintenance, and have a long lifespan, making them ideal for the unique environment of basement spaces. While wood windows offer a traditional look, they are prone to swelling and mold in damp conditions, making them less practical for basements.
Selecting basement window types that suit your needs and local weather conditions can make a big difference in the comfort and appearance of your basement. For residents considering new or replacement basement windows in Portland, OR, the right materials and styles can increase energy efficiency and prevent moisture-related issues, ensuring long-lasting quality and aesthetic appeal.

Basement windows are often referred to as egress windows or hopper windows. The term “egress window” typically applies to windows that meet specific size and accessibility requirements set by building codes, making them large enough for a person to exit through in an emergency. Hopper windows open inward from the top and are commonly found in basements because they are compact and fit well in smaller, below-grade wall spaces. Some homeowners also install casement windows, which swing open like a door, particularly if they need a larger window that serves as both an emergency exit and a natural light source.
No, not all windows are suitable for basement installation due to unique basement needs for ventilation, moisture management, and safety. Most basements require windows that are durable, resistant to moisture, and meet local building code requirements. For example, egress windows are mandatory in many regions for finished basements, as they provide an emergency escape route. Windows specifically designed for basements also often have insulated glass and specialized sealing to keep moisture out and prevent drafts. Using standard windows not meant for below-grade installation may lead to water intrusion, mold, and insufficient insulation.
A standard basement window size varies depending on its intended use, mainly whether it is meant to serve as an egress window. For egress windows, the International Residential Code (IRC) specifies a minimum width of 20 inches, a minimum height of 24 inches, and a minimum opening area of 5.7 square feet. This generally results in dimensions around 24 by 36 inches for a typical egress window. Smaller hopper or slider windows, which are often used in unfinished basements for ventilation rather than as emergency exits, can have dimensions as compact as 12 by 24 inches, depending on the basement’s depth and layout.
