Vinyl Vs Composite Windows: Don’t Waste Your Money

The world of windows has a ton of options for window types. With so many, it’s hard to make a good decision without getting overwhelmed and anxious about whether you’re making the right choice of not.

We’ve looked at various window frame comparisons such as vinyl vs aluminum and vinyl vs fiberglass. Now it’s time to compare vinyl vs composite windows.

Composite windows are the newcomer to the scene, they are much more modern and complicated. Vinyl’s been around the block for a couple of decades so far and remains at the top of the popularity list for new window replacements. But which one is better?

By the end of this article, I hope that you’ll be more confident in the decision that you’re making instead of wasting money on something that costs a lot but might not provide the most value.

What are Vinyl Windows?

Vinyl windows are the most common type of material used for window frames today. It’s durable, budget-friendly, and widely manufactured.

This material is made of polyvinyl chloride, which is also known as PVC. You may have heard of PVC pipes already in your plumbing systems. Vinyl windows are basically a plastic synthetic manufactured material. This makes it resistant to water, moisture penetration, mold, mildew, and rotting.

What are Composite Windows?

Composite windows are a more modern window frame material. It’s also a manufactured material. It’s called composite because it’s composed of various other materials that are blended together.

Composite windows end up looking a lot like wood windows without the downsides of wood, such as the constant maintenance and moisture issues that wood may have.

The most common type of composite window is made of wood on the inside that’s surrounded by aluminum cladding on the outside to keep the lifespan high and maintenance low. There are other types of composite windows as well that use different materials.

Vinyl vs Composite Windows: The Basics

The primary difference between vinyl and composite windows is that vinyl is a plastic material, whereas composite windows are made up of wood and aluminum.

The difference in materials makes everything else differ as well, such as lifespan, energy efficiency, cost, durability, aesthetics, and more. We’ll be diving into each aspect of vinyl and composite windows to compare them side by side.

Vinyl vs Composite Windows: The Differences


Windows are expected to last 20+ years. With that much time, you probably don’t want to be doing constant maintenance to keep your windows looking sharp and functioning properly.

Luckily, vinyl and composite windows are both low maintenance. Neither require painting or staining to maintain their color.

You also don’t need to worry about rot either. The aluminum cladding of composite windows protects the interior wood from any moisture penetration. Vinyl is plastic, therefore it can’t rot even when exposed to moisture.

Vinyl will warp over time, especially when it’s exposed to extreme temperatures. Composite, which has an exterior of aluminum, won’t do that.

If you live in a place with moderate temperatures in the summer and winter, vinyl will perform great and last a long time without any additional maintenance.

Verdict: Tie.


Windows add a lot to your home’s curb appeal. If you want your neighbors, friends, and family to talk about your new windows, you definitely want them to look good.

Vinyl windows cannot be painted, but many manufacturers have many options for colors, styles, and finishes. You can make them look like wood if you want.

Composite windows don’t have as many options. They’ll typically resemble wood. Here are some examples of different finishes Andersen Windows has to offer for composite windows.

Verdict: It depends on what you are looking for, but vinyl has more overall options for colors, styles, and finishes.

Energy Efficiency

Looks isn’t everything when it comes to windows. After all, what’s the point of looking good if your windows aren’t saving your any money on your energy bills?

Thankfully, both materials have great energy efficiency.

When facing each other head to head, composite windows will be more energy efficient. This is because wood is a better insulator than vinyl.

However, there are many other factors that go into energy efficiency, such as:

  • Type of window: Windows with more movable sashes will have less energy efficiency because they are not as airtight. Casement windows are more energy efficiency due to their compression seals.
  • Number of panes: Triple pane is more energy efficiency than double-pane, which is more energy efficient than single-pane.
  • Argon gas: An inert gas that’s pumped between window panes to reduce transmission of heat through windows.
  • Low E coatings: Microscopic layer on top of glass that reflects heat.

Verdict: Composite windows have better energy efficiency, but other factors such as window features will affect energy efficiency more.


Okay, so composite windows are better at insulating your home from outside heat and cold… but what about the cost?

Well, vinyl windows end up being more cost-effective than composite windows. Despite having slightly lower energy efficiency, vinyl windows exist in a goldilocks zone for price and performance. That’s why it’s so popular when homeowners pick their replacement window materials.

There are more vinyl window manufacturers as well, so they’re able to make more and sell it at a more affordable price.

Verdict: Vinyl windows are more budget-friendly and more widely available from many manufacturers.


As we’ve mentioned before, neither window material needs a ton of maintenance. That’s why they’re so popular. Homeowners like us don’t want to be constantly fixing our windows.

Vinyl is prone to warping in extreme temperatures, especially high levels of heat. Composite windows do not warp or crack, even under extreme conditions.

If you live in a place with moderate climate, you can pick either one.

Both vinyl and composite windows are not susceptible to rot or moisture.

Verdict: Composite windows can withstand more extreme temperatures, which gives it an edge over vinyl windows.
