Floor-to-ceiling windows, often referred to as window walls, instantly give a space the feeling of open, airy elegance. Abundant natural light and an unhindered view help blur the line between the outdoors and the indoors. These window walls are lovely to look at, but what exactly should you think about before installing them? What are the pros and cons? Consider what you need to know when deciding on whether floor-to-ceiling windows are the right choice for your home. 

The Pros and Cons of Floor-to-Ceiling Windows

Considerations for Installing Floor-to-Ceiling Windows

With their spacious views, window walls offer beautiful scenery. But this viewing aspect goes both ways: your neighbors can see just as much inside your home as you can see out of it. For someone living in a rural area or somewhere with a scenic view, such as over a lake, this may not be a cause for concern. But for someone living in an urban area with neighbors or frequent foot traffic, privacy is a factor to consider. 

Also keep in mind the loss of wall space associated with installing floor-to-ceiling windows. While these beautiful windows make a small room feel larger, they also eliminate available space that could be used for storage, furniture, or other essential home items. Therefore, it is important to consider whether a large wall with no function beyond offering a view is a realistic option for your room layout.

On a related note, you’ll want to choose the right location in your home for a window wall. Be sure to consider what your view will be like when deciding on where to place floor-to-ceiling windows. If the only wall you can place them on faces another building, it probably isn’t the best fit for a window wall. On the other hand, if you have a view of a lake, a forest, or some other scenic landscape, a window wall would really make your location shine. Also consider what room they will be in. Kitchens, living rooms, and bedrooms are the most popular choices for a window wall. 

The type of window you choose will change the look of your window wall, making it another important aspect to consider. Options include large, single-pane windows that offer unobstructed views, multiple smaller windows that form geometric designs, or cathedral windows. 

Energy Efficiency

There are two sides to the energy efficient coin when it comes to floor-to-ceiling windows. You'll use fewer lights since your room will be full of abundant natural light during the day. However, you also have to prioritize the most energy efficient windows to reduce losing heating or cooling through the windows.

Cleaning

With more glass, comes more cleaning. From a ladder to an extendable squeegee, your window washing routine, both inside and out will become more extensive. To maximize light, you'll want to clean your windows regularly.

Safety

If you skip drapery or blinds, then there's little privacy with floor-to-ceiling windows. This can be a safety risk if you live in an urban area, especially one that could be prone to break-ins.

Light

The biggest benefit of floor-to-ceiling windows is all that gorgeous natural light! However, if you're south-facing, you should also consider how that could impact fading on furniture and fabrics.

How Much Do Floor-to-Ceiling Windows Cost?

Because of their size and complexity of installation, floor-to-ceiling windows are more costly than small, standard-sized windows. The cost of each window will be different depending on the materials, coatings, size, and type of window—whether you select operable or inoperable (also called a fixed window).

Other factors that affect the price include installation fees and whether or not structural elements need to be reworked to support such large windows. On average, floor-to-ceiling windows may cost anywhere from $1,000 and upwards. Many factors can influence the price such as ceiling height, frame materials and how much work is required for installation.

Because such a large amount of wall space is going to be replaced with glass, be sure to inquire about the type of glass and glazes being used. Energy-efficient windows are the best choice, since they are designed to keep your home’s temperature steady. Such large glass areas can let in a lot of cold or heat, depending on the light and temperature outside. It’s also important to consider the materials of the window frame itself, since wood, fiberglass, and vinyl have their own advantages and disadvantages. 

You can also offset energy loss from floor-to-ceiling windows by using thermal curtains. These curtains can act as a layer of insulation, keeping warm in. Curtains can also block direct sun, which can assist in keeping a room cool during the summer months. 

Are Floor-to-Ceiling Windows Right for My Home?

Floor-to-ceiling windows can make an impact across architectural styles. Sleek modern homes were designed with abundant light in mind, making them a natural choice. However, a light-filled bay window that extends floor-to-ceiling can also look stunning in an old Victorian or a stately Colonial.

Floor-to-ceiling windows also make a space look bright and airy, which is particularly helpful in small spaces. However, make sure you have adequate wall space before you commit to taking up precious real estate with floor-to-ceiling windows.

Alternatives to Floor-to-Ceiling Windows

If you decide that floor-to-ceiling windows aren't right for you, whether it's due to privacy, space, or maintenance concerns, there are alternatives to bring in light. You could try clerestory windows across the ceiling, above your standard windows. You could also install a big picture frame window which provides a clear connection to the outside, but without reaching from floor-to-ceiling. You could also do sliding glass doors if you need functionality in addition to light.
