Choosing the Right Windows for Your Home

New corner windows on home.

If your windows have seen better days, replacing them with energy efficient, double pane windows can significantly reduce your heating and cooling bills while adding value and curb appeal to your home.

However, selecting the right windows for your home can be overwhelming given all the styles, materials, and features that are available to choose from. In addition, since this project is a major investment and new windows are expected to last up to 20 years, doing some homework before you make a decision can save on headaches later on.

New or Replacement Windows

One of the first decisions a homeowner must make is between “new” and “replacement” windows. Here is the difference:

New Windows

New windows are usually installed when the homeowner wants to change the size or shape of the current window opening and put a completely new window in its place. This generally requires the work of a contractor to complete the installation and surrounding carpentry.

While new windows generally do not cost more than replacement, the additional labor adds to the overall price. A big advantage of new windows is that you have the option to completely change the appearance and feel of your home both inside and out.

Replacement Windows

Installing replacement windows involves removing the old windows without disturbing the surrounding trim or frame, and replacing them with new windows or sash that are designed to fit right into the existing opening. Replacement windows cost around the same as new windows, but there is less labor involved in the installation, so the overall cost is less.

Replacement windows are a great option when the existing frame is still in good condition or when the trim is attractive and fits the décor of the home. Obviously the savings on labor costs are helpful when budget is a consideration. Depending on the manufacturer, replacement windows can be a stock size or they can easily be custom ordered to fit any opening.

Window Styles

Once you have decided between new and replacement windows the next decision is the style or type of window you would like. The four most basic and popular types are:

Double hung window.
Double hung window.
    • Single or Double Hung Windows: These are among the most common windows and are found in most homes. They consist of two separate sash (the actual pane of glass in the inner frame), which open or close by sliding up or down. A single hung window opens from the bottom only by sliding up, while a double hung window can be opened from either the top or the bottom.Double hung windows are ideal for creating air flow through the home when you lower the top sash. They are especially suited to homes where there are small children as they prevent the danger of a child climbing out the bottom window. (Remember: window screens don’t support the weight of a small child.)
    • Casement Windows: These windows usually consist of one large sash that’s hinged vertically and opens by swinging out. Usually a lever or other mechanism is used to open this style of window.
    • Awning Windows: These windows are hinged at the top and opened by tilting the window out from the bottom. As their name suggests, awning window create the appearance of an awning when open. These windows are most popular in coastal areas and in bathrooms.
  • Slider Windows: These windows slide open from side to side and are an excellent choice when there is limited space outside to swing the window open.

Window Frame and Sash Materials

Once you have determined the style or type of window, next you have to consider the materials the windows are made from. The most popular window materials today are wood or vinyl. There are also variations including “wood clad” windows. Aluminum frame windows are also available, but are less popular since they aren’t as energy efficient as vinyl or wood.

    • Wood Windows: Wood is both beautiful and had good insulating properties to resist heat and cold. However, the natural look of wood involves considerable maintenance. Besides periodic painting or staining, wood windows must be treated to protect them from moisture, movement, and rot.
    • Vinyl Windows: Like their cousin vinyl fencing, vinyl windows have become one of the most popular choices among homeowners. Vinyl is virtually maintenance free, provides excellent insulation, is reasonably priced, and looks great.
  • Vinyl Clad Windows: These windows offer the beauty of wood on the inside with a vinyl coating on the wood frame outside. This offers the maintenance free feature that makes vinyl so popular, while giving the beauty and natural feel of stained or painted wood on the inside.

Choosing Window Glass

Next you must choose the type of glass for your windows. Recent advancements in technology have greatly expanded the choices available in window glass. Besides choosing between double-, triple- or even quadruple-pane glass; you also get to decide on the distance between the panes.

The number of panes of glass doesn’t increase the insulation factor of the window, rather it’s the air between the panes of glass that provides the additional insulation. Most manufacturers today use an inert gas (usually argon) between the panes that insulates better than air alone.

Window with plant.

    • Low Emissivity (Low-E) Glass: Low-E glass refers to glass with a special microscopically thin, virtually invisible layer of material on the surface of the glass which acts to reduce the amount of heat that can flow through the glass itself.
  • Impact Resistant Glass: While if you wack this glass with a baseball bat it may crack, but it will not shatter and spread glass shards all over the place. The beauty of impact resistant glass is that under extreme weather conditions it holds up beautifully. And of course the occasional stray baseball won’t leave you with a big mess to clean up.

Window Quality

When choosing windows, one tried and true rule of thumb is that you get what you pay for. While cost is certainly important, it’s even more important to choose a quality product made by a well-known company. It is imperative to choose a well made window that will provide the energy savings, ease of use, and low maintenance to hold up over time.

Window Warranties

Carefully examine the warranties offered by the various window manufacturers, especially concerning the glass itself, since fogging between the panes is a common complaint on insulated glass windows. This is where a well known company with a good reputation will serve you well. Companies that have been around for a while are more likely to be around in the future should your window have problems or need replacement parts or sash.

Choosing a Window Contractor

There are several ways to find a good window installation contractor, but your best bet is to choose the window you want first and then look for a contractor who is especially trained by that manufacturer. Of course, as always, a great idea is to call your local Home Builder’s Association to find window installation contractors in your area.


  1. You are featured on The Simonton Collection web page! I would like to know why Simonton and Home Depot do not publish or show on their web sites their costs and specifications?

  2. Hi. I just replaced a few casement windows in my home and now that I compare them to what I previously had, I’m not sure about the quality. They seem very clear on the surface, no visible imperfections. However,at night, when looking through them, our reflections are distorted. There seem to be warps. This is not detectable in the daytime. What do you think? Thanks!

  3. have you ever seen hundreds of small imperfections or etches on a patio door with tempered glass. I recently purchased a triple pane door, with low e glass and notice scratches on each pane. I am being told this is a normal characteristic of tempered glass, and a because of the extra handling involved in making a triple pane door. I am thinking this is bull. This is very noticable especially with the sun shining in.

  4. I loved your definition of replacement windows as we’ve experienced a horror story. In Phoenix Arizona, we paid Reliant Capitol LLC (Century One Builders) over $26k in full to replace all 37 windows in our home to upgrade our home. Since then, we are in a multi-year battle to fix our home. The AZ Registrar of Contractors ordered them to fix my home on June 9, 2009. As of today,2 years later, my house is still falling apart. Search for reliantruinedmyhouse for the full story.

  5. I am looking at replacing my windows that are mostly worn out. Reliant Capitol has given me an estimate but I know nothing about them.. Can you provide any information regarding this manufacturer?

  6. Where on the window can you find out what kind of window it is? My back windows all are foggy and I understand the video you have on line to drill holes in them and wash them does not work. Is this correct. What else can I do, is there usually a warranty on the widows. My house is 14 years old. Thanks

  7. I want to know how to choose the best quality windows to put in my home. It has become very confusing. Which manufacturer is the best?

  8. I want to know what is the difference between gas filled windows and only glass (double glass ) and which one is better? l live in Florida. And which frame is better, metal or plastic? Which manufacturer is the best?

  9. This is a great article! I would also consider the following tips:
    1. Match windows to the climate you live in.
    2. Some window features are beautiful but come with a high price tag, so choose your features wisely.
    3. Pay attention to the u-factor value.
    4. Pay attention to the solar heat gain coefficient.
    5. Check to see how much light the window allows to come through.
    6. Do some online research on at least three replacement windows brands (including installers) before settling.

  10. Hi Abdulla,
    French doors are a really good choice to get light into your home and it’s stylish too. It provides proper ventilation too. If you are looking for a good installer , please try Clera windows in Canada. I got their help to replace the windows of my bedroom and kitchen.

  11. This is some great information, and I appreciate your point that vinyl windows don’t require much maintenance. My husband and I just moved into an older home, and we want to put in some more energy efficient windows. I’d rather not have to take extra care of the frames, so I’ll definitely look into having vinyl ones installed. Thanks for the great post!

  12. My windows open towards where the freeway is by my house. I think if I were to get new windows, I would make them so the face the opposite direction because the freeway is pretty noisy. I thought it was a good point that you can consider making changes when you get new windows. I know I would make a good list of changes

  13. I am in the process of building a new home and need to decide on what type of windows I want. Thanks for all your information, I especially liked your comment about vinyl windows I have a vinyl fence in my house right now and have loved it. I didn’t realize that window frames can be vinyl as well. I will definitely call my contractor to see if we can do a vinyl window frame.

  14. I did the calculations for soffit vents by reading your article.I’ve got 1650 square feet of attic. That is 1650÷150=11 square feet of net free ventilation.Then take 11÷2=5.5 for intake or soffit vents and 5.5 for exhaust.I’ve got 12×8 soffit vents. So that’s 96÷144=.66 of net free per vent.5.5 ÷.66=11 soffit vents.Well I have 22 of them.Owen Corning has a ventilation calculator online that gives you blank for you to add your attic square feet and it calculates your net free ventilation area.I did their formula and it said I need 408 net free vent area or 20 soffit vents at 20 net free equals 400 and 32 feet of ridge vent at 12.5 net free area per foot

  15. That’s a great tip you gave about how it’s imperative to choose a well made window that will provide the energy savings, ease of use, and low maintenance to hold up over time. I’ve heard that certain types of windows are capable of lowering your energy bill by up to 50% because of their efficiency! I’ll have to make a smart choice as my wife and I look into multiple window options for our new home.

  16. Thanks for the helpful tips. You wrote that awning windows are hinged at the bottom, and open at the top. My grandmother wants to replace the windows in her home, and asked me to do a bit of reading on the subject. I think these awning windows would be nice, as it would make it hard for anything to get in the window if you were to accidentally leave it open.

  17. A close friend of mine had a window break and they need to get a replacement. You mentioned that you should consider what kind of glass you want, as that is based on the needs you have. I know my friend will probably want impact resistant, as his son likes to play ball and that is what broke the last window.

  18. The best part of your blog for me is when you talked about how you can consider installing wood windows if you’re looking for a type of window that’s aesthetically good looking and has the ability to resist heat and cold. My sister is looking to find the best materials for the windows that she’s looking to install in her new house. It’s important for her to make sure that the windows that she will install offer a classical look without compromising its functionality. It will make sense for her to consider wood windows that will surely enhance the beauty of her windows. Thanks for sharing this.

  19. Hello, you have a great blog. It consists of almost all the details one must consider while choosing the right windows for house.

  20. I’m currently building a house and I need to start looking at the different window styles I can choose from. I was thinking about adding double-hung windows to all areas of my house. I like that you mentioned that this type of window is perfect for creating airflow.

  21. It’s helpful to know that replacing windows is cheaper than putting in new windows since the opening doesn’t need to change. My wife and I have been considering getting better-insulated windows in our front room, and recently our son helped push us towards that decision by cracking one of the panes with a toy. We’ll probably look into getting a replacement window that can keep that same location intact and help keep our home properly insulated.

  22. The windows in my home are REALLY old and starting to crack. Because of this, I need to replace them. I like how you mentioned that vinyl windows are typically maintenance-free. That sounds right up my alley!

  23. Since my home construction is nearly done, I think it’s just about time to consider finding door materials too. I think I might go with the vinyl window type as it does not require much maintenance and it provides excellent insulation.

    • Congratulations on your new home, Victoria!
      We’re glad this article could help with the next steps.
      Good luck. 🙂

  24. My husband and I decided that we’re going to FINALLY do it. We’re going to make the BIG move. We want to move closer to our work location (we both work in the same office. It’s how we met. Strange but true!) and we want to build a home! We want a great design that is PERFECT for the environment we live in and is great for our kids.
    So we are thinking that high impact windows would be great since we get high winds and flying debris occasionally!!!

  25. I appreciate you helping me to understand the different styles of windows. I would like to purchase some new windows for my home. It seems like it would be a good idea for me to get energy-efficient windows.
