Most homes will feature more than one style of window. But most designers advise against mixing too many different styles in a single home, as it creates a disjointed look. It’s very likely that when you replace a single window you will stick with the same style, but large-scale replacement of all windows at the same time gives you the option of changing the style of all of them for a more radical makeover. House style also plays a role in window selection because certain window styles are often associated with defined architectural styles. Common windows styles include:
Double-hung windowsDouble-hung with muntinsCasement windowsAwning windowsSlider windowsFixed windowsRoof windows or skylightsBay or bow windowGlass block windows
Here are considerations for these popular window styles.
Uses
Double-hung windows are used most often in homes with classic traditional styling, though they are also found in traditional-modern homes. The classic rambler, farmhouse, and bungalow styles, for example, make extensive use of double-hung windows.
Pros
Double-hung windows are made by many manufacturers, so your selection is very wide. Prices are generally reasonable, due to the wide availability of this window type. Double-hungs are normally easy to open and close, thanks to springs or weights. Tracks are vertical, so they generally don’t fill up with dirt.
Cons
Over time, counterbalance springs can wear out or sash cords can break. These windows require occasional maintenance to keep them operating smoothly.Large opening can make this type of window a break-in hazard for determined intruders.
Single-Hung Windows
A variation on the double-hung window style is the single-hung window. Single-hung windows are similar to double-hung windows in that they both have two separate, upper and lower sashes. The difference between the two is that the upper sash of a single-hung window is fixed in place, allowing only the lower sash to be operable. Single-hung windows have the same pros and cons as double-hung windows, but do offer some benefits regarding energy-efficiency. Generally, they are considered a lower-cost alternative to double-hung windows.
Uses
A double-hung-with-muntin window is used in much the same way as a standard double-hung, but it gives a slightly more classic, ornate look that might be appropriate for colonial-style, Victorian style, or other classic styles.
Pros
Same as for standard double-hung windows.Provides an old-style classic appeal.
Cons
Same as for standard double-hung windows.With true muntin windows, the muntins may separate from the glass over time, compromising the energy-efficiency of the window.Fake muntin grills can look cheap and inauthentic.
Uses
Casement windows have slightly more modern style than double-hung windows, and when properly positioned, they can be very useful for catching and directing cooling breezes into the home.
Pros
Casement windows are considered better than double-hung windows at keeping out drafts since the window seal is generally quite tight. Casement windows are good when you want to “scoop” cooling outside air into the house. Casement windows tend to be relatively secure against intruders—the open space is fairly narrow when the windows are open.
Cons
When fully extended, casement windows can be broken off by strong winds. Mechanical cranking mechanisms are subject to wear and have a high failure rate.Casement windows do not qualify as egress windows unless they are quite large.
Uses
They are frequently used in low-level windows where intruders might be a problem, or in wet climates where you want to open windows even when it is raining. Small awning windows are often used in the basement or in below-grade applications.
Pros
Awning windows are fairly secure against intruders.The windows can be left open during light rain since the glass serves as an awning that prevents water from entering.
Cons
Awning windows do not scoop in outside fresh air as effectively as casement windows. Like casements, the mechanical cranks on awning windows are subject to wear and have a high failure rate.
Uses
Slider windows are popular in mid-century modern homes styles (they were popular in new construction during the 1950s and 60s). Sliders are a good choice when you need to constantly open and close windows.
Pros
Sliders have no cranks or mechanisms, so they are very durable. Windows tend to be cheaper than other styles, due to the simplicity of their design.
Cons
Tracks can fill with dirt and debris, requiring frequent cleaning. Sizes and shapes are limited.
Uses
Fixed windows are used to provide view or light where ventilation or egress is not a need.
Pros
Fixed windows are permanently sealed, so they offer better energy savings than other windows types. Simple design lends itself to modern home styles. Fixed windows tend to be cheaper than other window styles
Cons
Fixed windows can create too much energy gain in warm, sunny climates.Because they can’t be opened, fixed windows provide no means of admitting fresh air.

Uses
Roof windows and skylights are most useful for introducing light into attic spaces or upstairs spaces where wall space for windows is limited. They can also improve light and ventilation in large “open-concept” rooms through the use of framed shafts, or chases, that extend from the skylight through the attic to the ceiling below.
Pros
They provide a good way to add light to the attic and second-story spaces. Venting roof windows can help exhaust hot air in summer.Constant, direct exposure to the sun means these windows can help heat spaces in winter.
Cons
Skylights and roof windows take a heavy beating from sun and rain; these windows are prone to problems and have a shorter lifespan than other windows. Installation generally requires a pro, since cutting open a roof is beyond the abilities of most DIYers.
Bay and bow windows are traditionally formed with a fixed center picture window flanked on the sides by one or more pairs of double-hung or casement windows.
Uses
A bay or bow window can be used as a visual centerpiece in large living rooms, family rooms, or parlors. They very often look out on an attractive view or a landscaped setting, such as a front yard.
Pros
Bay or bow windows create a design statement like no other home feature. These windows are ideal where you want a constant view of the outdoors. These windows offer shelf space for growing plants or displaying decorative items. Small bay windows can serve as greenhouse windows for growing herbs and other plants.
Cons
Bay or bow windows are quite expensive. Installing these windows requires a considerable amount of framing work, including headers and roof coverings. The large surface area often lacks the proper air sealing which can create a heat loss issue.
Uses
Glass block windows are most commonly used in bathrooms or other spaces where you want to introduce light while obstructing visibility. Glass blocks can also be installed in foundation walls to introduce light into basements. Some styles include ventilating panels built into the unit.
Pros
Glass block walls are the most secure of all windows since the heavy, thick blocks are mortared in place permanently.Glass blocks are semi-opaque, so they are ideal for areas where privacy is important.These windows have very good insulating properties.Glass blocks are very durable; such windows rarely need replacement.
Cons
Glass blocks can be difficult to integrate into a home style. These windows are often utilitarian, rather than decorative. On south-facing walls, glass block may heat up indoor spaces.
