Vinyl vs. Aluminum Windows: Which Should You Choose?

Replacing your home’s windows doesn’t have to be overwhelming or super expensive. Two of the most popular types of window frames are vinyl and aluminum. Both are affordable options that offer different benefits. Vinyl offers better insulation and energy efficiency, but aluminum stands up better to extreme temperatures and won’t fade like vinyl does when exposed to sunlight. Keep reading to decide which window type is right for you.

Vinyl vs. Aluminum Windows: Key Differences

There are many differences when it comes to aluminum vs. vinyl windows. Some of the most crucial to consider are window frame replacement cost, appearance, customizability, energy efficiency, and durability.

Vinyl windows are a bit more expensive, but they often look nicer, can be customized to look like higher-end wood windows, and provide better insulation and energy efficiency for your home.

Aluminum is one of the most affordable window frame materials. It resists warping and fading more than vinyl in response to sun exposure. However, it can’t be made to look like higher-quality materials and is less insulative than all other materials.

What Are Vinyl Windows?

Vinyl windows have a frame made out of polyvinyl chloride (PVC). PVC is a lightweight and affordable material with decent insulating properties, making it a popular type of window frame.

Vinyl windows are durable and come in a variety of appearances, so they can fit many different home styles. But these windows do have some downsides, particularly when it comes to withstanding extreme weather.

Best For: Boosting your home’s energy efficiency and curb appeal if price isn’t your primary concern.

Pros of Vinyl Windows

There are many benefits for homeowners who decide to add vinyl replacement windows. Some of the pros include the following:

• Low maintenance: Unlike aluminum frames, vinyl windows don’t tend to chip or need to be sealed or repainted over the years, so maintenance is minimal. Plus, the material is easy to clean.

• Style: Vinyl can be made into a variety of different styles, even replicating the look of higher-end window frame materials, like wood.

• Great insulation: This type of window offers better insulation than aluminum, which can save you money on utilities in the long term.

Cons of Vinyl Windows

Vinyl windows aren’t perfect, though. They have some issues that homeowners should consider before installing them. Some potential problems with vinyl windows include the following:

• More expensive: Vinyl windows cost much less than those with wood, composite, and fiberglass frames, but they aren’t as affordable as aluminum frames.

• Vulnerable to extreme temperatures: Vinyl may warp or crack with prolonged exposure to extremely high or low temperatures.

• Can’t easily be painted: If you later decide the look of the vinyl color you chose isn’t your style anymore, you’ll likely have to replace the window frames. You can technically paint over vinyl, but the paint won’t last long.

• Environmental impact: Manufacturing vinyl windows requires the use of many chemicals. To offset this issue, manufacturers may make recyclable vinyl windows to lessen the impact, but PVC is still less sustainable than aluminum.

What Are Aluminum Windows?

Aluminum windows have frames and sashes made from aluminum. Aluminum is a durable material, although it doesn’t have the greatest curb appeal, and it can show damage more readily than vinyl if it does get dented or scratched.

Best for: Homes in mild climates and homeowners looking to save money

Pros of Aluminum Windows

If you need some strong windows that look sleek, aluminum may be the right fit for your home. Some benefits of aluminum windows include the following:

• Low cost: Aluminum windows are less expensive than other types, including vinyl, wood, and fiberglass. Aluminum windows cost about $75 to $400 each.

• Modern look: These windows have a contemporary look, ideal for modern homes or commercial buildings.

• Temperature resistance: Unlike vinyl, aluminum is strong against extreme temperatures, so it won’t warp or crack in response to temperature changes.

• Resistant to extreme weather and sunlight: Aluminum windows are popular in areas prone to storms and hurricanes, because the material can withstand high winds. They also won’t fade in response to constant UV radiation exposure like vinyl will.

Cons of Aluminum Windows

Aluminum has some excellent qualities as a window frame, but it also has some features that make it less suitable for certain homes. Some cons of aluminum windows include the following:

• Prone to damage: Although they resist structural damage from strong winds and extreme weather, aluminum windows can easily dent and scratch upon impact.

• Less insulation: Aluminum windows aren’t as energy-efficient as vinyl because they’re less insulating, so they are best for areas with mild climates.

• Require some retouching: Because this material can scratch or rust easily, you may need to retouch it with paint or sealant from time to time.

Vinyl vs. Aluminum Windows

The clearest difference between vinyl windows and aluminum is the material from which the window frames are made. Aluminum windows are made from aluminum, while vinyl windows are made from PVC, which is the same material used to create pipes, trim, siding, and fencing.

Cost: Aluminum Windows

When replacing your windows, expect to pay between $85 and $2,500 per window, depending on the material, brand, and service provider you choose. 

Aluminum windows are sturdy and can last between 20 and 25 years. The average aluminum frame costs between $75 and $400. A single vinyl window will set you back between $100 and $900, depending on the size, making vinyl the more expensive option upfront and in the long run, as it lasts 15 to 20 years, on average.

Styles: Tie

Most manufacturers that make vinyl and aluminum windows offer an equal variety of window styles with frame options. Those include double-hung and single-hung windows, picture windows, bay windows, skylights, and more.

Durability: Tie

When it comes to vinyl vs. aluminum windows, both options are pretty durable. Vinyl may not be as great at withstanding extreme temperatures, but it won’t rust or dent like aluminum. Aluminum is vulnerable to corrosion, but it holds up against high winds, storms, and extreme temperatures better than vinyl. Ultimately, you’ll need to consider your climate when deciding which type of durable window frame you’ll need in your home.

Life Span: Aluminum Windows

Aluminum window frames can last between 20 and 25 years, depending on the brand and the quality of the installation. Vinyl windows have a life span of between 15 and 20 years. If you’re unsure about the age of your current windows, you can talk to a window company near you to determine how much it will cost to replace your windows.

Maintenance: Vinyl Windows

While the upfront cost might be a sticking point for you, it’s not the only time you’ll spend money on your windows. When considering the cost of repairing damaged windows, the material can make a difference, too. Vinyl windows rarely need maintenance, while aluminum frames are susceptible to corrosion.

Aluminum windows may need to be repainted or otherwise maintained, which will cost you a bit more over time. They’re still more affordable, but for low-maintenance window frames, vinyl is the best option.

Energy Efficiency: Vinyl Windows

One major reason you may be considering replacing your window frames is energy savings. Replacing your windows can lower your utility bills and keep your home more comfortable. 

While aluminum windows are stronger and last longer, the metal frames conduct heat. This means your home will hold more heat in the summer and cause your HVAC system to work harder. In the winter, the aluminum won’t insulate against the cold as well, either.

Vinyl still offers much better energy efficiency, so it’s the preferred option in both hotter and colder climates.

Environmental Impact: Aluminum Windows

In terms of environmental impact, aluminum is 100% recyclable with no loss of material integrity or quality. PVC manufacturing not only generates and requires chemicals that are harmful to the environment, but it’s not nearly as recyclable as aluminum.

Vinyl windows do improve your home’s energy efficiency, which should reduce your carbon footprint to some degree because you’ll use less electricity, oil, or gas to heat and cool your home. However, aluminum is still more eco-friendly than PVC due to its recyclability.

Appearance: Vinyl Windows

Both aluminum and vinyl windows can provide attractive window frame options. Aluminum windows have thinner frames and allow for a more modern aesthetic, while vinyl frames add a touch of modernity to an otherwise classic look.

Some companies manufacture vinyl windows with imprinted wood grain to make the material look like higher-end wood products. Aluminum doesn’t have these same options. While you can’t paint vinyl windows and you can paint aluminum, many companies offer colored vinyl frames for added customization. 

With all that being said, most homeowners prefer the appearance of vinyl windows over aluminum ones, especially given the customization options.
