Strength
Aluminum window frames are by far the strongest material available - it's the principal reason that aluminum frames are almost always found in commercial buildings. Of the five main frame materials in the replacement market (wood, aluminum, vinyl, fiberglass, composite), only aluminum is commerically rated - it is some 8 times stronger than vinyl. Aluminum frames are a good candidate for very warm climate due to their strength (conversely vinyl can begin to warp at temperatures over 110 degrees). Vinyl frames are a bit all over the board when it comes to strength. Low grade extrusions made for builder grade purposes are not going to fairly weak. Well made extrusions with foam fills and several chambers are going to be plenty strong for most homeowners and will hold up for a good 30 to 50 years. Mid range vinyl windows should last 30 years or more.
Style
If you like the more industrial style of aluminum windows, then certainly they will get the nod in this category. Aluminum windows are often preferred for modern or loft buildings as they offer a more commercial or modern look. These windows generally have thin frames, perfect for a picture window where you want an abundance of light. However, there are far less manufacturers of aluminum windows as compared to vinyl. Therefore, vinyl windows offer a wide array of frame colors and finishes, they may come in a wood or faux wood interior, have more hardware options and features etc.
Energy Efficiency
Vinyl replacement windows will offer better energy efficiency over aluminum. Modern aluminum windows are thermally broken, which has significantly improved their energy efficiency compared to aluminum frames of old. However, they still aren't a match for a decent vinyl window. Vinyl windows have good numbers when it comes to the "R Values," which means they can save you money in the long run when it comes to your utility bills. R values rate the windows performance when it comes to insulation. Higher values mean good insulation. Aluminum windows shouldn't be used in cold climates due to how they transfer cold (even if they are thermally broken, which all aluminum window manufacturers now use) - they are good for very hot climates.
Cost & Value
Well made vinyl windows should offer a really good investment and fall into the price range of $200 and $750 installed, with a mid range window costing $425 installed. Aluminum windows are not as popular as vinyl, therefore there are more limited options available, which in turn increases the price. Aluminum replacement windows cost is anywhere from $350 to $950 per window installed, with a mid range option costing $650 installed. Are aluminum replacements worth the extra cost? For homeowners living in extremely hot climates or those who absolutely love the more industrial look, aluminum is a great option. For most other homeowners, a well made vinyl window is probably the way to go.
Vinyl vs Aluminum Windows In Phoenix
Hi Dane, I live in Phoenix AZ.
I have 23 aluminum windows that are at least 30 years old that I want to replace.
I love your website however most if not all of the window recommendations are for windows not sold in our area (especially highest Vinyl options).
Can you recommend some high quality Vinyl windows for the Phoenix area?
Thanks.

Tamas, appy to provide you with the list for Phoenix. Replacing your old aluminum windows for new vinyl windows makes a lot of sense. With that heat though, you really have to go with a high quality option.

Aluminum vs Vinyl Windows
Hi Dane, thank you for your email. We started off getting quotes for all aluminum and these are attached. We found them very expensive and that made me look around for materials other than wood, aluminum clad or aluminum. Since we are in a high fire risk zone, wood is not a great option for us. We will be off grid so I am now considering composite for greater efficiency.
Out of curiosity I was wondering if zipcode matters to dealers because it seems prices are higher when the zipcode is say Santa Barbara as compared to Santa Maria or Oxnard. Any comments on this? My husband is convinced that pros charge as per zipcodes of the build.

Protima, I think the zip codes matter. When the sales person goes out on the job, he is basically trying to make as much money as the market will bear. So if he goes into a more affluent community his thought process is that they are willing to pay more. Getting a number of bids and going back and negotiating can usually get the prices to where they should be. Have you tried Anlin? I will send you my California based recommendations.

Thermal Barrier Aluminum vs Vinyl
Dane, I am currently researching new windows to replace 30 1988 era aluminum windows. I don’t know much about vinyl other than staying away from “builder-grade”. I read your comments on how aluminum is not as efficient as vinyl. On a comparison level, how much difference is there between Thermal Barrier Aluminum and vinyl if both have Argon filled dual pane construction with Low-E366 glass?
Thank you for your help.

Steve, if you want to experience aluminum vs. vinyl windows, go to your local starbucks and take a seat by the window — they use a commercial grade thermally broken aluminum window. Feel the frame in the morning, it's cold to the touch. Go at 1 in the afternoon and feel a window with direct sun on it — its hot.
Next time you go to a friend's house, check their vinyl windows (most houses have vinyl windows) and feel the difference in temp — very little change unless it's super hot or super cold. Interesting experiment to be sure!
Most homeowners should stick to a high quality vinyl window. A top end Simonton, Ply Gem or PGT is a good option in Florida.
