Clerestory. This is an old term that may be new to you. It refers to a certain type of window that you’ve probably always wanted but never knew how to ask for. If you do know what they are, you probably picture cathedrals.
This is because lancet windows are often clerestory windows that are on the top floors and balconies of churches. But of course, this isn’t even where the first clerestory windows were built, and not the only place they are used today.
The truth is that clerestory windows are a lot more common than you may think. Anyone can have clerestory windows, not just old cathedrals that use lancet windows to gain height. Here is what you need to know about clerestory windows.
What Are Clerestory Windows?
A clerestory is any windowed wall that is higher than the roofs around it. They appear as a row of windows high above eye level that let the light shine down inside to give your room a heavenly appearance.
They are common in modern homes as the pitches of the roof are more forgiving. In older homes, there isn’t much room for clerestory windows, though they do exist. Most clerestory windows in residential buildings have been added on.
Window Vs. Clerestory – What’s The Difference?
Now it’s time to get into a few questions about clerestory windows before we get started on the other aspects of them. These questions are quite common and you’ve probably asked a few of them already.
The first question is a simple one. What’s the difference between a clerestory and a window. The answer is that there is no difference as windows are a category and clerestory is a type of window. Simple as that.
What Is The Purpose Of Clerestory Windows?
People usually get clerestory windows for that celestial shine that it gives a room. But they also offer other benefits. For example, you can use only clerestory windows to let there be light without the windows taking up entire walls.
In warm climates, clerestory windows are often preferred because they let in the same amount of light as low windows but the light is less harsh. This is because the sunlight is filtered above, leaving your room lighted but not too hot.
When clerestory windows are added above other windows, they make it appear as if the entire wall is made of glass. There can be a support beam between the two window rows so you get the effect without the danger of having a wall of windows.
How Do Clerestory Windows Work?
Clerestory windows are installed high above the normal placement for windows. Because of this, the sunlight can reach much farther and far deeper than standard windows would. The angle of the windows can help enhance this.
So the first thing that helps them function is that they are high above the other windows. The second thing what is going on on the outside of the house. If there is an overhang the effect won’t be as dominant.
Are Clerestory Windows Fixed?
This truly depends on the clerestory windows. Most of the time, the clerestory windows are indeed fixed. But there are times when the windows can open just like any other window. However, they are usually opened for ventilation.
You’d most likely see clerestory windows open like awning windows or hopper windows. So they would open from the top or bottom and not slide like standard windows you’d see that are placed at eye level.
Which Direction Should Clerestory Windows Face?
Clerestory windows should either be placed on the north or south side of the house. They aren’t usually placed on the east or west unless there are clerestory windows on all for walls of the house on the outside.
A south-facing clerestory will need an overhang while the north side one will usually get less sun and will have a better chance of not overheating. Ensure that you have windows that will open if you live in a rather hot or cold climate.
How Tall Should Clerestory Windows Be?
This one is easy because unlike other types of windows, clerestory windows can be any size and really are made in all different sizes. There aren’t standard clerestory window sixes as the windows are usually built-in.
Some clerestory windows are a foot wide by two feet long while others are ten feet wide by twenty feet long. Narrow is usually the go-to but you can make wider clerestory windows as long as they are hung high.
History Of Clerestory Windows
Now that you know what clerestory windows are, you may be interested in their history. According to Britannica, one of the first uses was in the huge hypostyle hall of King Seti I and Ramses II at the Temple of Amon.
This was in the 1300s BC. The columns in these buildings were higher in the center, letting light in the center of the building. This was something that wasn’t thought of before then. But it sure was afterward.
By 300 AD, many Roman buildings were covered in clerestory windows. Fast-forward eight-hundred years and clerestory windows are one of the most popular windows in gothic and Roman architecture.
Clerestory Windows Inspiration
It’s great to know that clerestory windows aren’t just historical, they are current and even trendy. You can find a home that already has them or put clerestory windows in your current home. But do to that, you need to know what you’re looking for.
Although finding out more about interesting architecture is fun, what’s most important is finding a way to apply it to your life. These ideas and inspiration will give you something to work with as you design your new home.
Pitched Clerestory Windows
Interestingly enough, clerestory windows don’t have to be straight at all. They also don’t have to be slanted up on one side only. They can work with the pitch of the roof. After all, clerestory windows don’t have to be the highest point of the house.
This can work on the ends of the house only as they will have a pitch. Unless you add on and create an L-shape to accommodate pitched windows that you would normally see on the end of a house.
Inclined Clerestory Windows
Though these windows are inclined, the roof is. With roofs that are slanted only once and not pitched, you can always add clerestory windows to the higher side. Adding them to the slower side would disqualify them from being called clerestory windows.
If you do add clerestory windows to an inclined roof, consider using exposed rafters. This can add to the effect and give an open feel to the ceiling, making the space seem bigger and giving you more to work with.
Continued Clerestory Windows
In rooms that are set higher than the rest of the house, you can add normal windows and they can be considered clerestory windows. You can also make this effect even more powerful by adding floor-to-ceiling windows.
This looks amazing no matter what room it’s in, but it’s even better in the highest room in the house. The effect is modern, yet offers room to play with the design style and making it look rustic or chic as well.
Clerestory windows are perfect for any sunroom or naturally-lit bedroom. The two were created for the same reason. So that you can view nature and let natural light in without being bombarded by intense sunlight.
To make sure the light is only pleasing, never too intense, hire someone to add a protective gloss on your windows. This will not only stop the heat from the sun, but can also allow you to choose how clear the windows are from the outside.
Separated Clerestory Windows
Despite popular belief, you can have clerestory windows without having a row of narrow windows above other windows. Clerestory windows simply need to be higher than part of the roof. This gives a lot of room for creativity.
You can even put standard windows up above and call them clerestory windows. Remember Clerestory isn’t a design style, it’s an architectural style. So any type of window can be a clerestory window.
Dual Clerestory Windows
Another great trend is to add clerestory windows to two sides of a room. You can do even more, but usually, the architecture will only allow two opposing sides. This will make sure there is natural light coming in at all times of the day.
The lower windows are an option, and it really depends on your climate. If your house is often warm, the lower windows aren’t eccomedned. If your house stays cool, the lower windows can let extra heat from the sun in.
Faux Clerestory Windows
If your house just doesn’t allow you to add clerestory windows, you can always fake it out. Do this by adding glass doors on the bottom level and a support beam above it. Then, add large windows that reach as high as your structure will allow.
This makes it look as if the windows reach higher than the roof when really they are just below. They may not technically be called clerestory but they will look like clerestory windows and add the aesthetic you’re looking for.
What Is The Difference Between Transom And Clerestory Windows?
This is something that we thought we’d clear up. Upon first glance, these two windows look very similar. But it is their placement that really lets you know whether you are looking at a transom window or a clerestory window.
In general, transom windows are installed above doorways while clerestory windows are installed along the roofline on the inside of the house. Clerestory windows are higher than transom windows as well.
How Much Do Clerestory Windows Cost?
The windows themselves will cost the same as any other window. The only thing that makes them cost more is that they are usually multiple windows put together. So instead of paying for one window, you’re paying for three or four.
So the more expensive and unique the windows you choose, the more expensive the clerestory windows will be. Choose small, square windows for the cheapest total cost. Or hire someone to help you find out what’s best for you.
Cheapest Clerestory Windows
The cheapest “row” of clerestory windows will be about $500. This is for paned windows of a standard size ( or smaller), and that really is the cheapest you’ll pay. These are usually repurposed windows too.
If you want decent clerestory windows, you will pay more.
Average Cost Of Clerestory Windows
The average price of clerestory windows is about $1000. This is for standard clerestory windows, not standard windows used for clerestory windows. These windows come in all shapes, sizes, and materials.
Most standard homes will pay about this much as most people want regular clerestory windows. But some people have big dreams and need the best of the best to fulfill them. And that’s okay!
Best Clerestory Windows
For the nicest clerestory windows, expect to pay over $2000, likely up to $5000. These will be wood or steel and have the exact panes that you want. You can get the size you want as well, and choose whether they open or not.
If you have a $5000 budget, your dream can probably be replicated exactly. Any less and you may have to settle.
Cost Of Clerestory Window Installation
