Here are five indicators that it’s time to change your windows:

  1. You feel a draft of cold air in winter or heat coming through in the summer.
  2. There’s paint peeling around the exterior of your windows which may indicate condensation, mold or rot. If a hard tool pushes into the wood around your windows, it’s a sign the windows should be replaced.
  3. If you see cracks in the windowpanes or casing, they should be replaced.
  4. If you see condensation on the windows or between the windowpanes causing seal failure, that’s cause for replacement.
  5. Your windows no longer open or close properly.

Window Styles and Designs

We kick off our guide with 15 window styles.

1. Single-Hung Window

Single hung window style

The single-hung window is a classic and very common design. It operates with the bottom sash being manipulated. Since this type of window does not open outwards, it is a perfect choice of window for small spaces like windows facing pathways, streets and other narrow spaces.


  • Easy installation.
  • Perfect for narrow outside space.
  • Affordable.
  • Easily matches any home design.
  • Energy-efficient (less heat-loss).


  • Since only the lower stash is operational, this type of window requires you to clean it from the outside.
  • Ventilation can be limited.

Price Range: $100-$250 and up

2. Double-Hung

Double hung window style

The double-hung window is the most common type of window in American houses because of its practicality and functionality.


  • Very easy to source and comes in many designs.
  • Easy maintenance since both the upper and lower sashes can be manipulated to allow ventilation inside.
  • Like the single-hung window type, it is perfect for narrow outside spaces.
  • Affordable.
  • Energy-efficient.


  • Limited ventilation.
  • Depending on the materials and functionality, this type of window is not as airtight as other types.

Price Range: $200-$350 and up

3. Oriel

Oriel window style

The oriel is a type of window that is commonly used in upper floors/stories that are supported by brackets, corbels or similar. This type of windows extends the area of the room exteriorly.


  • Elegant and more ornamental.
  • Allows more natural light to enter the room.
  • Gives a panoramic view of the outside.
  • Like all other bay window types, it adds space to your room.
  • Makes your house look luxurious.


  • Not suitable for people who don’t want “extra sunlight” in their rooms.
  • Decoration for the window needs to be customized, meaning costly.
  • Window treatments could be expensive.
  • Can be costly.

Price Range: $1,000 and up

4. Cottage

Cottage window style

The cottage type of window is a variation of the double-hung window where the upper sash is shorter than the lower one. It is also commonly called as the “front window type.” Aside from the smaller upper sash, the features and characteristics of the cottage window are very similar to the aforementioned double-hung window. This type of window is also known as the “Georgian” and “Tudor” type of window.


  • Offers a classic design that never goes out of style.
  • Affordable.
  • Low maintenance.
  • Energy-saving.
  • Easily customizable and matches traditional house designs.


  • More difficult to clean than the double-hung window because of the smaller upper stash.

Price Range: $400 and up

5. Two-Panel Slider

2-panel window style

The two-panel slider is the most common type of sliding window. It has two panels where one or both of the panels slide left and right to allow ventilation into the room.


  • Affordable.
  • Easy to install.
  • Low maintenance.
  • Suitable for narrow outside spaces.
  • Complements classic and modern architectures.
  • Energy-efficient.
  • Durable and long-lasting.


  • Cleaning the outside (especially on upper floors) can be challenging.

Price Range: $250-$300 and up

6. Three-Panel Slider

3 panel window style

This type of sliding window is wider than the two-panel slider, thus provides a more panoramic view of the outside scenery. The three-panel slider has the middle panel fixed, while the other two side panels slide to the middle to open and close the window.

Pros and Cons:

Aside from the wider space, it has all the same pros and cons of the two-panel slider like low maintenance, durability and affordability.

Price Range: Depending on the materials used and durability, costs $300 and up.

7. Picture Window

Picture window style

The picture window is one of the most unique forms of windows since it is fixed (cannot be manipulated). It is just a glass windowpane which has the main purpose of framing an outside view — like a picture frame, thus the term “picture window.” Although not a common type of window it is used on houses with vaulted ceilings.


  • Affordable.
  • Low maintenance.
  • Easy installation.
  • The most energy-efficient type of window.
  • No curtains and blinds required for a majestic outside view.


  • No ventilation

Price Range: $250-$650

8. Deadlites (Sash Only)

Deadlites sash only window design

Many builders use deadlites and picture windows interchangeably, and when it comes to features, they are almost identical. The only difference between the two is that a picture window has frames while deadlites are “stand-alone” and frameless.


  • A very affordable type of window since it has only one sash. Highly energy-efficient like picture window.
  • Other advantages are similar to picture windows.


  • No ventilation.

Price Range: $150-$500

9. Hopper

Hopper window style

The hopper window is a type of a single-sash casement window (see number 10) which opens by tilting vertically inwards. Hoppers, usually horizontal rectangles, are hinged in the bottom which allows the tilting of the window to open from the top.


  • Easy to access and operate.
  • Energy-efficient.
  • Excellent insulation.
  • Great for narrow outside spaces since it opens inward.
  • Easy and low maintenance.


  • Tends to limit room space (opens inwards).
  • Possibility of water entry.
  • limits privacy.

Price Range: $100-$600

10. Casement

Casement window style

Like previously mentioned, casement windows are single-stash windows similar to the hopper, except they are installed vertically instead of horizontally. These are hinged windows that open inwards or outwards from the side.


  • Excellent for ventilation.
  • Low maintenance.
  • Good quality insulation.
  • Comes in variety of designs, sizes and materials.


  • Difficult to use with window screens since it usually cranks outwards.
  • Not very secure.
  • Size limitations.

Price Range: $270-$750

11. Awning

Awning window style

As mentioned above, awning windows are similar to hoppers except that instead of tilting inwards, they tilt outwards. The design prevents it from limiting the size of the room but cannot be installed where plants and other barriers of the space outside of the wall can prevent the window from opening.


  • Saves energy.
  • Provides good insulation.
  • Prevents snow and rain from entering the room.


  • Difficult to clean the outer portion of the windowpane.

Price Range: $420-$760

12. Transoms

When it comes to aesthetics, transom windows are the most common accent type of window.


  • Great for beautifying your home while allowing natural light to enter.
  • Provides good ventilation and insulation.


  • Difficult to clean.

Price Range: $200-575

13. Different Shapes

Different types of window shapes

  • Perfect for unique architectural interests.
  • Allows more natural light to enter.


  • Typically provides no ventilation.

Price Range: $250-$750 and up

14. Bay

Bay window style

Bay windows have an outward frame, commonly hexagonal, which adds space to a room.


  • Adds space and aesthetic touch to your room.
  • Gives an enhanced panoramic view of the outside.
  • Can transform the look of your house by adding an elegant touch.


  • Can possibly block narrow outside space.
  • Replacement and maintenance are costly.

Price Range: $1,150-$3,550

15. Bow

Bow window style example (illustration)

As what you might already know, bow windows are variations of the bay window. The only difference is instead of having hexagonal and straight edges, the bow window is curved, forming an arch. Because of the curved edges, this type of window is typically larger than bay windows.


  • Most elegant window designs.
  • Gives a panoramic view.
  • Adds space to the interior.


  • Costly.
  • Difficult to clean.
  • Not for people who don’t want “extra light and heat” inside the room.

Price Range: $2,000 and up

16. Jalousie

Jalousie style window (diagram)

When proper ventilation is your priority, then a jalousie window will serve you well. Jalousie windows have parallel glass, wooden louvres or acrylic that can be tilted open and shut simultaneously. Besides its outstanding function, its design is versatile enough to complement any type of house aesthetics.


  • Provides proper ventilation
  • Complementary design
  • Can maintain airflow during storms and rains with its slanted design.

19. Storm Window

Storm Window diagram

A storm window is mounted on the outside or inside of the main glass window. The second barrier on top of the original window helps keep the house warm during winter and cool during summer. This unique feature creates a solid seal that helps in the improvement of your home’s insulation while it protects it from outside elements.


  • More affordable than the typical double-pane windows.
  • Installation is very cheap.
  • Improves home insulation.
  • Increases efficiency of standard windows.


  • High maintenance.
  • Condensation between two layers may cause damage to wooden exteriors.

20. Egress Window

Egress Window diagram

Aesthetics is important, but actual function plays a much more significant role when it comes to home improvements. The good thing about the egress window, is that it caters to both safety and style. This type of window provides a safe escape route from your home in case of emergencies such as fire, earthquake, etc. and can also serve as an access point for emergency personnel.


  • Can serve as a safe escape during emergencies such as fire.
  • Brightens dark rooms, especially the basement.
  • Provides enough ventilation for the room.
  • Cost-effective and very attractive.


Can cause moisture problems if not properly installed.

  • Installation takes a lot of effort and planning.

21. Skylight

Skylight diagram

A skylight is a window installed in a roof or ceiling to add more natural light.


  • Brightens dark areas with natural sunlight.

  • Aesthetically pleasing and compliments well with any interior.


  • Expensive to install and maintain.
  • Can sometimes cause roof leaks.
  • Can potentially damage roof structurally.

22. Round

Round window diagram example

  • Provides unique architectural interest.
  • Easy to maintain.
  • Versatile design.


  • No ventilation.
  • Not ideal escape routes during emergencies.

24. Dormer Windows

Dormers create more space under angled roofs and make it possible to have windows in those spaces for natural light. Interestingly, there are quite a few different types of dormer windows.  See 10 types of dormer window styles here.


1. Double-Pane

double pane window cross-section illustration

Double-pane windows have two sheets of glass that are separated by trapped gas (commonly krypton or argon) in the middle. The gas makes a tight seal which holds the window more firmly, preventing heat and energy loss.


  • Prevent condensation on your windows, especially during winter.
  • Provides good insulation.
  • Because of the creation of a tight seal, this type of windows help block outside noise.
  • Increased security and durability.


  • It may not be a good match for old, ancestral homes.
  • Maintenance is costly since it can’t be repaired once broken — you need to replace the entire thing.

2. Triple-Pane

Triple pane window cross section

Due to architectural advancement and breakthroughs, triple-pane windows are becoming more and more popular. Unlike double-pane windows, they have three sheets of windowpane glass, separated by two separate layers of gas. Thetwo layers of airtight gasses provides improved insulation than the double pain.


  • Triple-pane windows are improved versions of double-pain. They have all the advantages/pros of the double pane — better insulation, better soundproof and lower condensation during winter.


  • More expensive than double pane.
  • Heavier than double pane, needs more durable window sash/frame.

3. Quadruple Pane

quadruple pane window cross-section illustration

The quadruple-pane window is by far, the most advanced type of windowpane. The insulation is made even better by combining four sheets of windowpane glass with three spaces filled with gas that are airtight. It significantly raises the functionality and features of the other two type of panes mentioned above. It is better in all the pros and advantages of all the panes listed above with the con of being super heavy weight and needs a tougher, more durable window frame and sash. Not to mention the more expensive price!

Types of Window Frames

1. Wood

Wooden frames are the most popular type used in most houses. They have both aesthetic appeal and classic appearance.


  • Easy to own, fix and replace.
  • Durable and long-lasting if well-maintained.


  • Requires maintenance.
  • Susceptible to insects and termites.
  • Expensive.

2. Vinyl

Vinyl window frames are made up of polyvinyl chloride (PVC’s). It is the same materials widely used in plumbing and pipes. This is a popular type of window frame due to its durability and affordability.


  • Low on energy cost.
  • Versatile material which can easily be made into various window styles and designs.
  • Low maintenance.


  • During extreme heat conditions, vinyl colors can fade (and can’t be repainted).
  • Low resale value.

3. Aluminum

Aluminum windows are used in both classic and modern architecture, due to their durability and longevity.


  • Outperforms wood and vinyl in noise abatement.
  • Low maintenance. Doesn’t shrink, split, fade or rust.
  • Weather-proof.
  • Matches classic and modern architecture.


  • Cheaper than wooden frames but cost more than vinyl or fiberglass.
  • Not very efficient as an insulator.

4. Fiberglass

Made of extruded fiberglass sections and formed into a frame and looks similar to a PVC window frame.


  • Fiberglass frame can be repainted and is far more durable than a PVC frame.
  • Low maintenance.
  • Weatherproof.
  • Best insulator frame.
  • Sound resistant.


  • Usually more expensive than wooden frame.

Best Types of Windows for Various Purposes

Energy Efficiency

Installing energy-efficient windows is a smart way to save money. Choose a double-paned window with Low-E glass for maximum energy efficiency. Low-E is a thin coating that helps to reflect heat, keeping the inside of your home more comfortable.

Windows with a vacuum-sealed argon fill may cost more, but they also help to conserve energy and should provide you with a decrease in your monthly energy bills. Check for windows with the ENERGY STAR label to provide exceptional energy efficiency for your home.

If you want maximum insulation, the new R-5 Series windows have a higher R-value that makes them better at retaining heat.

Standard ENERGY STAR-rated windows have an R-value of 3. A higher R-value reduces heat loss and can actually improve your home’s insulation levels by 30 to 40 percent. All windows with Low-E coatings or a gas fill are more insulating than those without these features.

Tropical Climates

Avoid windows with wooden frames if you live in a tropical climate since humidity and temperature fluctuations can cause the wood to expand and contract or rot. Instead, select windows with durable vinyl frames that can withstand the tropical weather. If you live in a storm-prone area like Florida, aluminum storm windows are highly recommended.

Choose windows that include energy-efficient glass or coatings to help keep your home nice and cool when temperatures and humidity levels rise.


The best windows for bathrooms are easy to open for improved ventilation. Look for casement and awning-style crank windows that are easy to open and close. Unlike sliding windows, when crank windows are closed, they create an airtight seal to prevent heating and cooling loss.

When they’re open, they provide much-needed ventilation in moist, humid areas of the home, like bathrooms. Choose privacy glass crank awning windows for your bathroom so that you can enjoy safety and privacy whenever you open them.


White kitchen with wood-framed window, potted plants, and a Farmhouse kitchen sink.

For the kitchen, choose sliding windows that are easy to open. Install a sliding glass window above your kitchen sink to enjoy the view and to get more air circulation. A garden window is great for growing fresh herbs and vegetables indoors.

These large windows have glass on each side that allows the sunlight to reach your plants from every angle. Double-hung windows are also one of the best options for a kitchen. That’s because these windows can be opened from the top or bottom, providing you with more control over air circulation and ventilation while you’re eating or cooking.

A sliding glass door is another great choice that leads to the outside for patio dining.

Living rooms

Living room windows come in a myriad of styles, including large picture windows that allow you to enjoy the view outside. Bay windows are also a great choice for living rooms since they can also double as a seat or a small shelf or table. To give your living space some personality, choose custom architectural windows available in a variety of unique shapes and sizes.

If cleaning your windows is a concern, choose double-hung windows that you can access from the top and bottom for easy care.


Always choose bedroom windows that lock for added security. When it comes to energy efficiency, casement windows are an excellent choice for bedrooms. These windows create an airtight seal when they’re closed to keep the heat in your bedroom during the winter, and the cool air in during the summer.

They’re also a great choice for bedrooms since they can swing in or out, allowing you to open the windows and get airflow inside. Bay windows are also lovely for a bedroom, but you’ll want to invest in some custom blinds or curtains to ensure privacy.


Large sunroom with gray wood-panelled walls, French doors, a seating by the bay window, potted plants, and dark hardwood flooring.

The key to choosing windows for a sunroom is their durability, weather resistance and easy maintenance. Choose large windows with a sturdy aluminum frame or try vinyl windows that can handle a lot of direct sunlight. Large, tall windows are ideal since they provide you with the best views of the outside while also allowing as much sunlight in as possible.

Select windows with a special Low-E coating to block UV rays so that your flooring and furniture don’t fade. Sliding glass doors are also a great option for sunrooms.


Hopper windows are a good choice for basements since they can be opened from the bottom. These narrow windows will provide your basement with extra airflow without letting too much light in. A hopper window uses a lever that you pull down to open them, or you can choose to install awning windows.

These windows open from the bottom and have hinges at the top. It’s important to choose basement windows that are insulative, well-sealed, and easy to open and close. The key is to install windows that will keep rain and weather out to prevent moisture damage.

Window Buying Guide

Now that you have a good understanding of your window options, what else should you look for? Here are some tips.

  • ENERGY STAR and NFRC labels: Energy Star label means your windows meet the EPA’s minimum standard for insulating in your area.
  • In colder climates, consider gas-filled windows with low-E coatings to reduce heat loss. You can also get a low U-factor for better thermal resistance. U-factor is the rate at which the window conducts non-solar heat flow.
  • In warmer climates, choose windows with coatings to reduce heat gain. Look for a low solar heat gain coefficient (SHGC). SHGC is a measure of solar radiation admitted through a window. Low SHGCs reduce heat gain in warmer climates.
  • In climates that are both hot and cold (i.e. have seasons), get windows with both low U-factors and low SHGCs.

Frequently Asked Questions

Below are answers to commonly asked questions about glass windows.

How long do glass windows last?

Glass windows are fairly long-lasting but can last even longer with proper maintenance and care. The average time for glass windows to last is between 15 and 20 years without extensive maintenance and up to 30 with proper care.

The lifespan of your glass window is also affected by the type of area in which you live and whether or not there is a significant amount of tumultuous weather (i.e. thunderstorms and snow). However, the type of frame you use also has a huge impact on the lifespan of a window.

For example, wooden frames can last for 10 to 20 years on average but have been reported to last up to 30 years. Aluminum frames last even longer, ranging between 15 to 40 years. Vinyl frames are arguably the most durable, lasting anywhere between 20 and 40 years with proper care.

Can glass windows be painted?

Yes, but you must make sure that you have the correct type of paint. For example, acrylic paint can be useful for not only decorating your window, but also making the window itself more durable.

In order to allow the paint to increase the lifespan of your window, you should get acrylic paint that has a baked-on capability. The feature might not be labeled as such, but you’re essentially looking for something that will become harder when exposed to direct sunlight.

Can glass windows crack on their own?

Yes, glass windows can crack on their own. However, it’s more nuanced than you might think, and is caused by a variety of causes. The phenomenon is referred to as Spontaneous Glass Breakage and is usually the result of how the glass was tempered or installation errors.

It is difficult to tell if there is a problem with the glass, though, as it typically cracks spontaneously at random or in tumultuous circumstances.

If you want to prevent your glass windows from breaking, we recommend that you read up on Spontaneous Glass Breakage so you can be aware of the risks and be properly prepared.

Can glass windows be repaired?

Glass windows can be repaired, but the specific type of repair necessary will depend on just how severe the damage is. For example, it is possible to look at small cracks in a window and reinforce the glass so it does not break any further, while larger cracks may require the entire window to be replaced.

If you are unsure about whether or not your window needs repair, it’s important to do your research and consult a professional for their opinion. If you don’t do this, you put yourself (and your window) at risk.

Are glass windows load-bearing?

Whether or not glass windows are load-bearing depends on the specific type of frame and brand you purchase. Aluminum glass windows are not load-bearing, meaning that you should exercise caution when looking into those specific types of windows.

However, there is no surefire way to tell if the windows you’re looking into are load-bearing. If you want to be absolutely sure, consult a professional and look for products that specifically advertise load-bearing capabilities. After all, the ones that are load-bearing will definitely advertise that.

How are glass windows made?

Glass windows are typically made by melting various minerals. The temperature for the melting process is often so high (around 3090 degrees Fahrenheit) in order to melt the specific components into one substance. The most common element in glass is often silica, a compound that is also often found in sand.

Once the compounds are all mixed into one liquid, limestone is added to the mix in order to make sure it does not dissolve. The addition of limestone results in glass-forming, with this molten glass being shaped into various objects. In the case of windows, the molten glass is molded into window shapes to be sold after it properly cools down.

It’s worth noting, though, that this process will change slightly depending on the specific kind of glass that you’re making and which types of materials you’re using.

Can glass windows be resealed?

To put it simply, yes. However, if the crack is too substantial to be resealed, it isn’t very likely that it is possible. To understand whether or not the window you want to fix is resealable, you should contact a professional to get a proper estimate and evaluation.

Can glass windows be recycled?

In the United States, it’s far less common that glass windows can be recycled. Contrary to popular belief, not all types of glass are made the same, making certain recycling facilities not interested in having to sort through glass windows.

The reason why glass windows are often different from bottles and other types of glass that you should recycle is that the glass is treated, making it difficult to break up and subsequently to recycle.

However, this does not mean that you shouldn’t try to recycle windows if you have the chance to. There are organizations that have been specifically created to help people recycle windows properly and we recommend you look into one of those facilities in order to recycle your windows properly.

Another recommended option for those looking to recycle glass windows is to consider ways in which you can reuse your windows, whether it be through repairing them first or installing them in a context that works.

Theater companies are also always on the lookout for functioning props, so, even if you can’t use your cracked window at home, perhaps your window can become part of a new play.

Can used glass windows be sold?

Yes, but it is often tricky to sell glass windows at any comparable market prices. The only situation in which someone would actually want to purchase your glass windows is for historical preservation purposes, so it’s unlikely that someone will take you up on it.

However, if you happen to have a glass window that is of significant historical value, it is likely possible to sell it to a local shop. Even if the window pane itself isn’t usable anymore, you can likely still sell the frame for a good amount of money.

Are glass windows insulated?

Not all of the time. The insulation process that makes it possible to properly regulate the temperature of a room is typically achieved through the glass-making process.
