Single hung windows
Cost: $150 to $375 per window.
If affordability is the most important factor for you, single hung windows are the ones for you. These have two sashes - top and bottom. Only one sash moves, however - the bottom. It slides up, overlapping the top sash.
Jalousie windows
Cost: $175 to $400 per window.
The Jalousie window is often called a louvered window, and it is made up of horizontal slats or panels of glass that you can move to let in air or get a better view. These windows can also be made out of wood, plastic or metal and were first debuted in the very early parts of the 1900s. They were quite slow to become popular, which was around the 60s.
Transom windows
Cost: $200 to $600 per window.
Transom windows were given their name because of the horizontal beam that separates the door below from a window or similar above. The window itself appears above that, and is often a picturesque design, such as archways. These can be used above exterior doors, like the front door; but they can also be used inside the home, too.
Picture windows
Cost: $200 to $900 per window.
Picture windows are the kind of windows that you would perhaps usually associate with a shop or similar business. They are large panes of glass, with no seams, that basically cover a large surface area. If you had a beautiful view and you didn't care too much for privacy, a large picture window would be the kind of thing you'd install to enjoy panoramic scenes.
It is called a picture window because it literally looks like a picture hanging on the wall.
Hopper windows
Cost: $250 to $800 per window.
Hopper windows and awning windows are actually quite similar. The difference between the two is that hopper windows will open into the house, hinged at the bottom and opening at the top, and awning windows open out from the house, at the bottom, with hinges at the top.
Hopper windows are great for when space is an issue, and for kitchens and bathrooms.

Casement windows
Cost: $250 to $800 per window.
Casement windows are classed as “traditional windows” by many people. They are long, tall, sash-style windows that have hinges down the length of them and open out from the house or building. They open in much the same way as a door. Sadly, this means they are quite vulnerable when opened.
Circle windows
Cost: $250 to $750 per window.
Circle windows, as the name might suggest, are windows in the shape of a circle. They’re modern, unique, and great for bathrooms, entryways and closets — but with modern technologies and a wide array of materials, these quirky shapes can suit almost any room or space.
Arched windows
Cost: $300 to $500 per window.
Arched windows are also sometimes called radius windows, and can be dramatic and bold in design. Because of their unique design and the need for bespoke manufacturing, arched windows, circle windows, and other similar non-traditional shapes of window are usually more expensive than traditional shapes.
Sliding windows
Cost: $300 to $1,500 per window.
Sliding windows are a really good design idea when you are fighting a losing battle for space. They don't take up any extra room inside the property, nor outside, and they're often seen as a good alternative to casement windows.
Double hung windows
Cost: $400 to $600 per window.
These are one of the most common types of window used in home building and remodels, because they are easier to clean than their single hung cousins while still offering a range of looks at affordable prices.
Just like single hung windows, there are two parts - top and bottom. Rather than just one side moving up and down, however, both sashes can move. You can have the top sash open/closed, or the bottom sash.

Awning windows
Cost: $400 to $700 per window.
Awning windows are similar to hopper windows, but they work in the opposite way. This type has hinges along the top, pushing open from the bottom. It's a great window to have if you enjoy opening them in the rain, and it doesn't take up space inside the property when it's opened.
Glass block windows
Cost: $400 to $1,200 per window.
These windows let in lots of light, but do not let people view inside the property when installed properly, which gives them a lot of appeal. They've been in and out of fashion over the years, so some homeowners might find glass block windows outdated, but they certainly have a number of benefits.
Skylight windows
Cost: $850 to $2,500 per window.
Skylight windows have a whole host of benefits, including adding solar heating to that particular room of the house, and adding extra light to areas it might not get it naturally.
Skylight windows, because of where they are, do not make for an easy DIY job. It is highly recommended to get fully-trained and licensed window contractors in for this kind of job.
Bay windows
Cost: $1,000 to $3,750 per bay / $200 to $800 per window.
Bay windows can divide opinion a little bit, with some homeowners thinking of them as outdated, while others would argue them to be traditional. Adding more light, more windows, and providing a view are three things that will definitely add value to any home, however, so they are very much worth considering in your next remodel.
Egress windows
Cost: $1,000 to $5,000 per window.
Egress windows also double up as emergency escapes, which can make them perfect for rental properties or homes that have been separated into apartments. Bedrooms in basements are required in some places to have egress windows by law. At first glance, this type of window looks very much like any other kind of window.
Garden windows
Cost: $1,000 to $4,500 per window.
This window actually protrudes from the house, which is what has given it its name. It overhangs a little out into the garden (for example) therefore giving you a great view of the space. It is designed to be used as a sort-of greenhouse, with a sill as a space for plants.
Bow windows
Cost: $1,200 to $4,000 per full bow window.
Bow windows and bay windows are very similar, but a bow window will have more openings - four or five. Bay windows tend to have three openings. Because of this, bow windows are, as the name suggests, bowed in nature. They give the appearance of being rounded.
