14 Most Popular Types of Windows
For your convenience, we’ve structured this guide by starting with the basic old window types, then diving into specialty designs, and finally covering energy-efficient options.
1- Hung Windows
Hung windows typically have two sashes—movable parts with glass—that slide vertically, one above the other. If only one sash moves, it’s called a single-hung window. If both sashes move, it’s a double-hung window.
This compact mechanism makes hung windows perfect for small spaces. They provide excellent ventilation and insulation, especially with modern designs.

Best placement: Hung windows are ideal for rooms with limited wall space, such as bathrooms, kitchens, and small bedrooms.
| Pros | Cons |
| Budget-friendly | Limited ventilation |
| Easy to operate and maintain | Cleaning can be challenging |
| Provides excellent insulation |
2- Casement Windows
Casement windows have sash/sashes that swing open like a door to the outside. The opening-closing mechanism is typically operated with a crank and handle. Casement windows are popular for their energy efficiency; they seal tightly when closed. They also offer clear, unobstructed views and excellent ventilation.

Best placement: These are a great fit for hard-to-reach places, like over sinks or countertops, where their crank operation is more convenient.
| Pros | Cons |
| Excellent energy efficiency | Crank mechanism may wear out |
| Provides clear, unobstructed views | Requires clearance outside |
| Secure when locked |
3- Picture Windows
Picture windows are fixed glass panels designed to bring in natural light. Since they don’t open, they are highly energy-efficient and excellent for framing scenic views. Typically, picture windows are used in large spaces, but they can also fit in areas where you want extra openness and light.

Best placement: Picture windows are perfect for living rooms, dining areas, or spaces with scenic views that you want to frame like a work of art.
| Pros | Cons |
| Maximizes natural light | No ventilation capabilities |
| Energy-efficient design | Limited functionality |
| Low maintenance |
4- Sliding Windows
In sliding windows, the sash/sash slides horizontally overlapping each other when opened. If only one sash moves, it’s called a single sliding window; if both move, it’s a double sliding window, and so on. Sliding windows are simple to operate and have a minimalist design, making them very popular today. Plus they’re especially efficient in areas where vertical space is limited.

Best placement: Sliding windows work well in kitchens, bathrooms, or areas with expansive wall space that can accommodate a wide window.
| Pros | Cons |
| Easy to operate and maintain | Tracks may collect dirt |
| Provides ample light | Less energy-efficient |
| Cost-effective |
5- Storm Windows
Storm windows are secondary windows installed outside your regular windows to improve insulation. The air between the two windows acts as a cushion, reducing heat loss or gain. They also protect against harsh weather, like covering glass panes in the hot sun or preventing water damage in rain.
You can install storm windows anywhere, but they’re usually especially popular in older homes with single-pane windows.
Source: Pinterest
Best placement: Install storm windows in areas exposed to extreme weather, such as north-facing walls or coastal properties.
| Pros | Cons |
| Enhances insulation | Seasonal installation required |
| Protects against drafts and noise | May not blend with modern aesthetics |
| Affordable upgrade |
6- Transom Windows
Transom windows are small picture windows typically installed above doors or larger windows. While they’re often used as decorative elements to enhance a space’s architectural appeal, transom windows also help improve the flow of natural light. They are commonly seen around front doors, but can also be installed indoors.
Source: Pinterest
Best placement: Transom windows shine in entryways, hallways, or rooms that need additional light without compromising privacy.
| Pros | Cons |
| Adds architectural elegance | Limited functionality |
| Improves light flow | Professional installation needed |
| Customizable designs |
Specialty and Custom Windows
7- Bay & Bow Windows
Bay and bow windows are three-dimensional, multi-paneled windows that extend outward from the walls, creating extra space inside. Bay windows typically have three panels—one large central window with two smaller ones on each side, while bow windows have four or more panels arranged in a gentle curve for a softer look.

Best placement: These windows are a stunning addition to living rooms, bedrooms, or dining areas where you want to create a focal point and enhance space.
| Pros | Cons |
| Increases interior space | Higher installation cost |
| Enhances curb appeal | Requires structural support |
| Provides abundant natural light |
8- Skylight and Roof Windows
Skylights or roof windows are used in spaces where traditional windows aren’t feasible, such as attics, bathrooms, or rooms with limited wall space. However, nowadays they’re also becoming more common in living areas, complementing traditional wall windows. When the window is fixed it’s called a skylight but when it’s operable it’s called a roof window.

Best placement: Perfect for rooms with sloped ceilings or interior spaces that lack windows altogether.
| Pros | Cons |
| Increases natural light | May require professional installation |
| Saves energy | Potential heat gain/loss |
| Creates an open atmosphere |
9- Jalousie Windows
Jalousie windows are similar to blinds. Instead of flat window panes, they feature several horizontal slats that open and close together with the use of a crank mechanism. The biggest advantage of these windows is the excellent control they offer over airflow—you can adjust how much you open them to suit your needs.

Best placement: These windows work well in sunrooms, enclosed patios, or bathrooms where ventilation is a priority.
| Pros | Cons |
| Excellent ventilation | Poor insulation |
| Affordable and easy to repair | Security concerns |
| Unique retro aesthetic |
10- Arched Windows
Arched windows feature a curved or slightly pointed top, adding a dramatic touch to any space. They’ve been around for centuries and come in a variety of shapes and designs, making them perfect for any aesthetic. Arched windows usually create a dramatic yet sophisticated look and can bring unique visual interest to any space.

Best placement: Ideal for entryways, living rooms, or any area where you want to create a dramatic focal point.
| Pros | Cons |
| Aesthetic and elegant | Limited opening functionality |
| Allows natural light | Custom designs can be costly |
| Adds architectural charm |
11- Egress Windows
Egress windows double as escape exits or rescue access in case of fires or other emergencies. These windows are typically installed in basements or bedrooms and must meet specific building codes regarding size and opening requirements.
Source: Pinterest
Best placement: Ideal for basements and lower-level rooms where building codes require emergency exits.
| Pros | Cons |
| Ensures safety compliance | Higher installation cost |
| Increases natural light | Requires professional installation |

12- Awning and Hopper Windows
These are single-pane windows hinged on one horizontal side and free to open on the other. Awning windows open at the bottom and outward, creating an awning-like shape. They provide ventilation while keeping rain out, making them ideal for wetter climates. Hopper windows are opposite; opening at the top and inward. They are great for basements and small spaces where you want ventilation without sacrificing privacy.

Best placement: Awning windows work well in kitchens and bathrooms, while hopper windows are suited for basements and utility rooms.
| Pros | Cons |
| Allows ventilation in rainy weather (awning) | Limited opening size for airflow |
| Provides excellent insulation | Requires regular maintenance of hinges |

Energy-Efficient and Innovative Windows
13- Low-E Windows
Low-E (low-emissivity) are glass windows coated with a special layer that reflects heat and UV but allows light to pass through. This technology helps keep your home cooler in the summer and warmer in the winter, all while protecting your furniture from fading and reducing harmful UV exposure.

Best placement: Low-E glass windows are good for areas with extreme temperatures where energy savings and climate control are priorities.
| Pros | Cons |
| Reduces energy costs | Higher initial investment |
| Protects interiors from UV damage | May slightly reduce visible light |

14- Smart Windows
Smart windows can be turned transparent or private (tinted/foggy) with the push of a button. They are made with advanced technology with liquid crystals sealed between two panes of glass. When an electric current passes through them, the window becomes clear; when the current is off, the window fogs up, offering privacy and light control with just one window.
Source: Pinterest
Best placement: Ideal for offices, high-tech homes, and spaces requiring adaptable privacy and lighting control.
| Pros | Cons |
| Offers adjustable privacy | Expensive installation and maintenance |
| Reduces glare and heat | Requires power or automation |
| Enhances modern aesthetics | Limited customization options |
How to Choose the Right Windows for Your Home or Office
To select a window for your place, consider its functionality, energy efficiency, and long-term value:
Consider the Room Functionality
Different rooms have different needs. For instance, bedrooms benefit from operable windows for ventilation, while living rooms might prioritize large, fixed windows to maximize light and views. Kitchens and bathrooms require windows that can handle moisture and promote airflow. Tailor your choice to each room’s specific needs.
Assess Your Climate
Energy-efficient options like Low-E or tinted glass, which block heat and UV, are go-to options for hotter climates. On the other hand, buildings in colder regions benefit more from double- or triple-pane windows with insulating gas fills to retain warmth and reduce energy costs.
Energy Efficiency
In addition to glass, also check for features like superior insulation, UV protection, and airtight seals. Additionally, look for Energy Star-rated windows to lower your home’s overall energy consumption in the long run.
Aesthetic Appeal
Traditional homes, like those from the Colonial period, may benefit from classic styles such as arched, bay, or casement windows. For modern or eclectic homes, windows with clean lines—like sliding or hung windows—would complement the design better.
Budget and Maintenance
Finally, consider both the upfront cost and long-term maintenance. Some types like bow windows need higher upfront costs but offer additional space. Similarly, materials play a significant role in maintenance. For example, vinyl and aluminum are typically more affordable and easier to maintain than other materials.
Takeaway
Take the time to explore different types of windows and understand your needs before making a decision. A smart choice now can save you money and time in the future.
