Windows are a crucial part of any commercial building. They allow light in, improve energy efficiency, and enhance the aesthetic appeal of the structure. They must be flexible and strong enough to withstand harsh weather conditions. While window walls, storefront windows, and curtain walls may all look very similar – just floor-to-ceiling windows on a building – in truth, there are distinct differences between them.
Understanding the differences between window walls, storefront windows, and curtain walls can help you determine which type of window system is best for your building’s needs. Here’s what you need to know about what each of these types of window systems are like and what they’re best suited for so that you can select the ideal window system for your commercial building.
What Are Window Walls?
These are pretty much what they sound like: large sections of walls installed between concrete slabs in order to give you floor-to-ceiling windows. These aren’t load-bearing. Rather, the concrete slabs support the load of the glass, which is then fastened and sealed into place.
They’re installed from the interior of the building, which makes them more cost-effective than curtain walls, as they are both safer and easier to install. They’re also easier to maintain.
These are great for creating the illusion of a larger space. They’re also excellent for soundproofing and quality performance, such as water resistance.
What Are Storefront Windows?

These are non-load-bearing window systems. While the other two window systems can be installed on any floor of a building, these windows are usually only installed on the ground floor, the storefront. In some cases, they can extend up to the second floor of a building.
These windows are more focused on serving as attractive business entrances. They help attract business and deter potential thieves. When people can see what you have, and know that they can be seen inside your store, it helps with both security and business.
They are the least expensive option because they’re typically only installed on one floor. They’re also not as thick as the other two types of window systems talked about here.
What Are Curtain Walls?
People can easily confuse these with window walls, because both of these window systems can extend up a building. However, curtain walls sit like curtains, on the exterior structure of the building. They are made to span multiple floors. Like the other two types of window systems, these aren’t load-bearing.
They are the most expensive type of these three window systems to install because they need to be installed from the exterior of the building, which makes them both more difficult and more dangerous to install. They are also the thickest type of window.
These are made to be water and air-resistant, to help with energy efficiency, to reduce swaying, and to allow plenty of light into your space. They’re the best for the most amount of natural light in your building and for a sleek, modern exterior.
What Type Of Window System Is Best For You?

All three of these window systems are wonderful. Which one is best suited for you depends on the type of building you have and its needs. Storefront windows are best for stores, as the name implies. Both curtain walls and window walls are suited for commercial buildings, such as offices and apartments. You do tend to see curtain walls more frequently in office buildings and window walls in apartment buildings.
If you’re unsure of what type of window system is best suited for your needs, it’s best to consult with a professional commercial window company. They will be able to assess your needs and your budget and make suggestions that meet them.
