Vinyl Windows vs Aluminum Windows
Choosing between vinyl windows vs aluminum windows? Here is my take on what these two very different window materials have to offer consumers. Vinyl and aluminum often face off against one another in very hot climates in parts of Texas and say Nebraska. Outside of these hot regions, they rarely go head-to-head, mainly because aluminum makes very little sense in climates that aren't hot as heck.
Which Should You Choose? A well made vinyl window is probably the call in nearly all cases. This is because aluminum gets such bad energy efficiency ratings (metal conducts heat). In fact, you can test this by feeling a window in any commercial building during the hottest part of the day - don't burn yourself! The exception to vinyl over aluminum is (ironically) in very hot climates where the worry about vinyl bending or warping in the extreme heat can be a real thing.
However, the advances in the vinyl window industry over the past two decades means that top tier vinyl windows can deal with the heat. The issue is that there are hundreds of cheap vinyl window manufacturers whose products very well might warp over 20 years in the heat. So make sure you stick with very well made brands and units.

Vinyl is the least expensive window material on the market. This is one of the reasons why it accounts for nearly 70% of the replacement windows market. Simply put, most homeowners can only afford vinyl windows. My hope is that they avoid the worst vinyl windows on the market and stick with the good to great brands and series.

The Winner: Vinyl
Vinyl vs Aluminum Windows Cost
Aluminum is considerable more expensive than vinyl. How much more expensive? Perhaps 40% more for a "comparable" window, although there is a much smaller demand for aluminum. As well, there really isn't a low end aluminum window market, it tends to be only decent to very good brands and series. Bascially, no one is buying cheap-o aluminum windows.

Vinyl is very plain looking. I wouldn't say it looks bad, although cheap vinyl windows can look bulky and unseemly. Well made vinyl windows look fine on the outside. They can blend in fairly well with many exterior materials. On the inside, vinyl windows can be upgraded to a faux wood laminate. These laminates mimic the natural look of wood and, when done right, look almost as good as real wood windows. I tend to think this is the best of both worlds.
The Winner: Aluminum
Vinyl vs Aluminum Windows On Appearance
Aluminum windows look nicer in my opinion than vinyl. In fact, many real wood windows use an aluminum exterior cladding because the material looks sleek and because metal is a material often used on homes. The other thing about aluminum windows is that they can be much slimmer than vinyl because the material is so strong. Most consumers prefer a sleek or narrow window to a bulkier look.
Let's look at vinyl windows vs aluminum windows on strength and durability. While vinyl is a relatively strong material, it wasn't always that way. The first iterations or generations of vinyl were pretty weak and the material could bend or warp in hot climates. The industry has come a long ways by moving from PVC to uPVC, adding multiple chambers to the frame, and even adding additional materials like titanium to the vinyl molds. In 99% of U.S. climates, well made vinyl windows have enough strength and durability to perform great for residential households.

Strength And Durability
Aluminum is considerably stronger than vinyl. In fact, aluminum is the strongest of the five window materials on the market today (wood clad, aluminum, composite, vinyl or fiberglass windows). How strong is aluminum - every commercial building in America must use aluminum windows due to their considerable strength. This is the crux of why aluminum windows are popular in hot climates - they don't bend or warp. Yes, they get hot as heck in all that heat, but they last an incredibly long time.
Vinyl is a very good performer in terms of energy efficiency. Perhaps not as good as fiberglass, but not too far off the mark.

Energy Efficiency And Performance
Aluminum windows are very bad inin terms of their overall energy efficiency. They are made from metal and metal conducts heat and cold. Modern aluminum windows have come a long ways from the old single pane aluminum frames from the 50s. Today, aluminum windows are thermally broken, meaning there is a break in the metal from the outside to the inside. This prevents the heat or cold from entering as much. Still, they are pretty bad in terms of making a home energy efficient.
Here is our consumer review section from past consumers debating and asking questions about vinyl vs aluminum windows. If you have a question for us, we are happy to give you are best answers for your situation.
Hello, I've gotten 2 bids on wincore windows and 1 for Viwintech Windows. From Franklin Aluminum (a company I have some issues with due to previous work), independent installers of Jeff and Scott England, and then the viwintech was through Steve carter. Unfortunately I can't find many reviews for these people outside of a little word of mouth.
Johnathan, I have a lot more information on the Wincore 7700 (off the top of my head the window air infiltration rating of .07 on the 7700 single hung. Alternatively, I want to say that the AI rate on the Viwintech 6000 is .09, so very close. Basically, I think those two windows are very close to one another in terms of their overall quality. Both very good options, but I can't list the differences verbatim. Brands are equally good and both series are their premium offerings.

Window Frame Material Question
I guess I'm curious as to the difference in a Wincore 7700 series vs a viwintech 6000 is? I have a friend that works at a siding company that can get viwintech for what seems to be better pricing than wincore. Also, what is your opinion on aluminum windows as they look very narrow and sleek.

I would go with the one you can get the best price on, coupled with who is going to do the best install. Installation is half the battle so I think this is where you spend your time to really drill down on who to hire. (Check out our window installation cost calculator to find out more on labor costs.) At the end of the day, the windows are probably a wash and the quality of installation is going to be the difference maker.
In terms of vinyl windows vs aluminum windows, you are going to want to stick with vinyl for sure. Yes, aluminum is sleeker and stronger, but the energy efficiency of vinyl is so much better.
