Sunlight is known to boost productivity, so workers who have access to it from their office space are likely to be more productive. When designing office space, large commercial windows can help to maximize natural light, keeping workers energized and engaged.

Whether shopping for new commercial windows or you need to replace commercial windows that are old and inefficient, it’s important to choose windows that are designed with energy efficiency in mind. In this guide, well discuss the benefits of energy-efficient commercial windows, as well as the key features to look for when shopping.

Commercial Windows Styles

There are several factors that you must take into account when choosing the right type of window for a particular setting. These include:

  • The size and layout of the space
  • The climate and weather conditions
  • The level of noise and light pollution

Some of the most popular types of large commercial windows include:

Casement Windows

These windows have hinges on one side and open outward, making them ideal for spaces with limited wall space. They are also easy to clean and maintain.

Awning Windows

Awning windows are similar to casement windows, but the hinges are located at the top of the window instead of on the side. Awnings are often times used in combination with other types of windows, such as fixed panes.

Hopper Windows

Hopper windows have hinges at the bottom and open inward. This makes them ideal for basements and other rooms that require ventilation but might be difficult to reach.

Sliding Windows

Sliding windows have one or more horizontal panels that open by being pushed along tracks. They are often used in combination with other window types, such as casement or awning windows.

Fixed Windows

Fixed windows are exactly what they sound like. They cannot open or close. They work in combination with other window types that you can open for ventilation, such as casement or sliding windows.

Single-Hung Windows

Single-hung windows are similar to double-hung windows but have one movable sash. They are often used in combination with other window types, such as awning or hopper windows.

Double-Hung Windows

Double-hung windows feature two movable sashes that slide up and down. These work in combination with other window types, such as casement or sliding windows.

Pivoted Windows

Pivoted windows are similar to casement windows but have a hinge located at the top and bottom instead of one side. They are ideal for spaces that require ventilation but have limited wall space.

Metal Windows

Metal windows are strong, durable, and provide sound insulation. They are often used in industrial settings, such as warehouses and factories.

When to Replace Commercial Windows

Many business owners are unsure of when they should replace their commercial windows. Depending on the type of business, new commercial windows may be necessary every ten to fifteen years. There are a few factors that can speed up the need for new windows.

You may need new windows when there is a change in the buildings use or an increase in the amount of sunlight exposure. If the windows are showing signs of wear, such as cracking or fading, then it is also time to consider a replacement.

Business owners should work with a window expert to determine when new windows will be necessary to maintain the appearance and functionality of their commercial space.

Types of Windows for Commercial Buildings

There are a variety of materials used to construct windows for commercial buildings. The most common type of window is the aluminum window.


Aluminum windows are strong and durable, making them ideal for high-traffic areas. They are also weather-resistant and low maintenance.


Steel windows offer superior strength and durability, and they are also fire-resistant. However, they can be prone to rust if not maintained.


Fiberglass windows are another option. They are durable and low-maintenance, but they can be more expensive than other options.


Wood windows are a classic choice that can add an elegant touch to any building. However, they require more maintenance than other options and can be susceptible to rot and insect damage.

Tempered Glass

Tempered glass windows are strong and shatter-resistant. However, they can be expensive, and repairs may require the replacement of the entire window.

Laminated Glass

Laminated glass is made from two sheets of glass with a thin polymer layer in between. It offers sound insulation, energy efficiency, and security.


Vinyl windows are an affordable, low-maintenance option. They also offer excellent insulation and come in a variety of colors and styles.

Installation Tips for Commercial Windows

When installing commercial windows, it is important to consider the size of the window and the type of glass used. For large windows, professionals recommend using laminated or tempered glass for extra durability.

For correct installation, it is important to follow a few key tips. First, measure twice before ordering windows to ensure a perfect fit in your building.

Make sure that the surface is level. This will ensure that the window sits evenly and does not warp over time. Apply a bead of silicone sealant around the perimeter of the window opening.

This will help to create a water-tight seal and prevent leaks. Use shims to level the window and secure it in place. Once the window is level and secure, you can finish the installation by caulking and trimming around the perimeter.

To ensure issue-free installation it’s best to use a professional. By following these simple tips, you can ensure the issue-free installation of your commercial windows.

Commercial Window Maintenance Tips

Commercial buildings require special care when it comes to window maintenance. Due to their size and exposure to the elements, windows can become dirty or damaged. Here are some tips for keeping your commercial windows in top condition.

Inspect windows often for signs of wear and tear. Look for cracks, chips, or loosened glass.

Have a professional clean your windows at least once a year. Window cleaners will have the proper equipment and cleaning solutions to clean your windows without damaging them.

Immediately have any damaged windowpanes repaired or replaced to avoid the problem worsening and having to get an entirely new window.

By following these tips, you can ensure that your commercial windows will remain in good condition for years to come.
