The 8 Most Common Types Of Windows Found In US Buildings

When it comes to creating a comfortable living space or building, contractors know that selecting the right type of window is crucial. Windows not only provide ventilation and natural light, but they also contribute to the overall aesthetics and functionality of a space. In this post, we will provide a quick overview of various types of windows and their uses to help contractors make informed decisions for their projects.

Fixed Windows

Fixed windows, also known as Picture Windows, are the largest type of windows that bring ample light into a room. They are a popular choice for homeowners seeking to maximize natural light and unobstructed views without ventilation. These windows are fixed in place and cannot be opened or closed, making them ideal for areas where uninterrupted views are desired, like living rooms and bedrooms. With various sizes and shapes available, they offer flexibility in design and customization.

Inswing Windows

Inswing windows are a type of casement window that opens inward. They are hinged on the side and swing into the interior of the building when opened.

Inswing windows are known for their energy efficiency and tight seal, making them a popular choice for homeowners looking to reduce energy costs and improve insulation. These windows are often used in bedrooms, living rooms, and kitchens.

Awning Windows

Awning windows are hinged at the top and open outward from the bottom, allowing for ventilation even during rain. They are often placed higher on walls for privacy and increased airflow.

Double Hung Windows

Double hung windows are one of the most common types of windows found in homes. They consist of two vertically sliding sashes that can be opened from the bottom or top.

Patio Doors

Patio doors are a popular choice for homeowners looking to connect indoor and outdoor spaces. They come in various styles, including French doors and sliding doors.

French doors are hinged and swing open, whereas sliding doors glide along a track to open and close. Patio doors are often used in living rooms, dining rooms, and bedrooms, providing easy access to outdoor areas and maximizing natural light.

Jalousie Windows

Jalousie windows are a unique type of window that consists of multiple horizontal glass blocks. These slats can be opened or closed using a lever, allowing for precise control over ventilation and airflow.

These windows are commonly found in coastal areas and are ideal for bringing in a nice breeze on a cool day. They are known for their enhanced airflow but may have lower energy efficiency compared to other window types.

Casement Windows

Casement windows are a popular choice for homeowners due to their excellent ventilation and various material options. They are hinged on one side and offer two opening options: inside and outside. This flexibility makes them suitable for different rooms.

For instance, in the kitchen, an outward-opening casement window is preferable for easy access during emergencies like smoke or fumes removal. In contrast, for bedrooms, an inward-swinging option provides privacy and convenience for opening and closing the window without reaching outside. Casement windows are available in various materials, including wood, vinyl, and aluminum.

Hopper Windows

Hopper windows are a great option for smaller spaces or areas with limited wall space. They are hinged at the bottom and open inward, allowing for ventilation and natural light. Since they are commonly placed in high places there is often a lever that makes their opening easy and reachable.

Additional Types of Windows

There are many other types of windows available for specific needs and architectural designs. Some of these include:

  • Arched Windows: These windows have rounded tops, adding an architectural appeal to any home. They can be fixed or operable, providing ventilation and adding a unique design element.
  • Storm Windows: Storm windows provide an extra layer of protection against the elements. They are installed on the exterior of existing windows, helping to improve energy efficiency and reduce noise.
  • Bay Windows: Bay windows consist of three or more windows that project outward from the building, creating a cozy nook and increasing the interior space. They are often used in living rooms or dining areas.
  • Egress Windows: Egress windows are designed to provide an emergency exit in case of fire or other emergencies. They are required by building codes in certain areas and must meet specific size and accessibility requirements.
  • Skylights: Skylights are windows installed on the roof, allowing natural light to enter the space below. They are a popular choice for rooms with limited access to exterior walls or where additional natural light is desired.

Additional Factors to Consider

When selecting windows for a project, there are several additional factors to consider:


The spatial layout of a room, house, or building significantly influences the choice of windows. Large windows are ideal for living rooms, as they provide a panoramic view, create a sense of openness, and bring in ample natural light, making the space feel more expansive and inviting. In contrast, smaller rooms may benefit from strategically placed windows that maximize natural light while maintaining privacy and functionality. Additionally, considering the direction of sunlight and wind is crucial for optimizing comfort and energy efficiency within the space. Overall, the placement and size of windows should be carefully tailored to the specific spatial and functional requirements of each area within the home or building.


Windows are available in various materials, including uPVC, wood, and aluminum. Each material has its own advantages and considerations, such as durability, maintenance requirements, and energy efficiency. It is important to choose a material that suits the specific needs of the project and complements the overall design aesthetic.

Bird Safe Glass

In certain areas, building regulations require the use of bird-safe glass to prevent bird collisions. Bird-safe glass is designed to reduce the reflectivity and transparency of windows, making them more visible to birds. This can help prevent unnecessary bird fatalities and contribute to a more sustainable and eco-friendly building design.
