Differences Between Aluminum and Vinyl Windows

Aluminum and vinyl are the two most common materials that homeowners choose for their replacement windows.

Aluminum windows are lightweight but strong, making them a great option if you want something that can withstand the elements. However, this material is less energy-efficient than vinyl, and some homeowners don’t like the look of metal windows.

Those who want a more traditional look will often choose vinyl windows, also called polyvinyl chloride (PVC). Vinyl is the most popular window frame material today due to its affordability, durability, and ease of installation. Some homeowners avoid vinyl for thinking it looks too cheap; however, it comes in various colors and finishes to improve its aesthetic value.

Let’s take a look at the five main differences between aluminum and vinyl windows.

Appearance

Aluminum windows have a thicker frame than vinyl windows and come in a range of colors. Aluminum frames are typically finished in a smooth or powdered enamel coating for a modern style. You can repaint aluminum frames with enamel paint if the coating wears away.

Vinyl window frames come in several finishes, such as smooth, textured, and faux wood, offering greater customization for a contemporary look. While you can paint vinyl with vinyl-friendly paint, it’s usually not recommended. Painting vinyl can void the manufacturer’s warranty and it often doesn’t hold onto paint well.

Aluminum Windows	Vinyl Windows
Thicker frame	Suits contemporary styles
Smooth or textured finish	Wide variety of finishes
Can paint	Can’t paint

Durability

Aluminum frames are highly durable and can support heavy windows of different shapes and sizes. Although aluminum can withstand harsh weather conditions and extreme heat and cold, it’s not recommended for homeowners who live on the coast, as salty air can corrode and pit this material. The enamel finish on aluminum also fades more quickly in sunlight compared to the dyes in vinyl. Aluminum windows can last up to 25 years.

Vinyl is durable in most climates and won’t corrode, but extreme heat can cause it to crack, warp, or melt. You should occasionally check your vinyl windows and reapply caulk if necessary. Vinyl windows can last up to 40 years if they’re well-maintained.

Aluminum Windows	Vinyl Windows
Lasts 20–25 years	Lasts 10–40 years
Withstands extreme weather and temperatures	Susceptible to damage in extreme heat
Not recommended for coastal homes	May require homeowners to reapply caulk

Cost

Vinyl is one of the most cost-effective materials available for windows. Homeowners can expect to pay between $250 and $600 for vinyl window materials and $400 to $1,200 for aluminum. Replacing eight windows with aluminum frames could cost as much as $9,600 for materials alone. Homeowners could save between $1,200 and $4,800 for the same project by choosing vinyl over aluminum.

Material	Average Cost per Window
Aluminum	$400–$1,200
Vinyl	$250–$600

Energy Efficiency

Metal conducts heat and cold, making aluminum less energy-efficient than vinyl. You can purchase thermally improved aluminum, which is more energy-efficient, or install thermal breaks, which consist of extra insulation in the frame.

Vinyl naturally offers better insulation than aluminum, saving homeowners money on their energy bills over time. To maximize your energy savings even more, look for ENERGY STAR-approved windows.

Maintenance

Regularly wipe down aluminum to prevent moisture from building up and causing the frame to rust. Homeowners in coastal areas may have to do this more frequently. Use a special aluminum cleaner to clean and remove rust and lubricate moving parts. If the finish begins to peel or chip, you should paint these areas to extend the frame’s life.

Vinyl is easier to maintain than aluminum. If you live in an area with temperature extremes, frequently check the vinyl and caulking since it can crack over time. Reseal if you notice gaps in the frame or drafts in the house.

Aluminum Windows	Vinyl Windows
Check for rust and corrosion	Check for warping or cracking with temperature changes
Paint over peeled or chipped finish	Check vinyl and caulk periodically
Wipe down and clean to remove moisture and rust	Reapply caulk when necessary

DIY vs. Professional Window Installation

Most homeowners find window installation fairly complex, so hiring a professional contractor is usually best.

DIY Window Installation

Before you DIY window installation, you’ll need the right equipment, knowledge, and experience to get the job done correctly. Poor installation can lead to moisture and mold in your home. This is expensive to remedy, so you may end up calling a professional anyway. Window installation involves the following steps:

Removing the old frame
Taking accurate measurements
Cutting openings and fitting the new window frame
Installing the window
Sealing and weatherproofing

Doing this job yourself could save you on your window replacement cost, but there are other considerations, including the following:

Do you have all the necessary tools and equipment? This may cost less than labor, but you’ll need saws and drills to install a window.
How will you move the materials? If you pick up the materials, they’ll need to fit in your vehicle. Renting a large truck costs up to $100 per day. Shipping is possible, but free shipping may not be available.
How long will it take you to replace your windows? You might have to hire a professional if you can’t finish the job quickly.
Do you have enough help? You’ll need help to lift and install your window and frame, especially if it’s aluminum.

Professional Window Installation

A professional window installer will measure and fit the window, making necessary adjustments and ensuring it’s level and sealed. Here are several advantages to hiring a professional casement window installer:

A professional knows how to create a watertight seal to avoid mold and damage from moisture.
You can ask for help with window placement in the house and get advice on whether you should choose aluminum or vinyl windows.
You can avoid building code violations.
A local pro knows what permits you’ll need.
A professional can perform custom or complex window installations.
Contractors can purchase materials at wholesale costs, which are lower than retail prices.
Reputable window installers often provide warranties or guarantees on their work.

How To Hire a Pro

Here are some steps to take when hiring a professional window installer.

Check online reviews for window installers in your area and ask friends and family for their recommendations.

Look up the business on the Better Business Bureau (BBB), Yelp, Trust Pilot, and other similar sites.

Get a quote from at least three window companies and ask about their experience, availability, and rates.

Check whether the company has the proper licensing and insurance in your state.

Ask for a timeline of the project.

Get cost estimates, guarantees, or warranties in writing.

Our Conclusion

Whether you choose aluminum or vinyl windows depends on your budget, needs, and aesthetic preferences. On average, vinyl windows are the more affordable option and require less maintenance than aluminum. Vinyl can also save you more over the long term by reducing your energy bills. Aluminum does better in extreme temperatures, but it’s not the best material for wet and humid climates.

We recommend contacting local window installation companies for quotes and assistance with your window installation needs.

FAQ About Aluminum vs. Vinyl Windows

Which lasts longer: vinyl or aluminum windows?

How long vinyl and aluminum last depends on how well you care for your windows and the climate in which you live. The average life span of vinyl windows is between 10 and 40 years, while aluminum lasts 20 to 25 years. Aluminum windows aren’t the best for coastal regions as the salty water and air cause oxidation and pitting, reducing the life span of your windows. Extreme heat can shorten the life span of vinyl.

What is the disadvantage of aluminum windows?

Aluminum windows have several advantages but are only recommended for some homeowners. Salty water and air in coastal areas can cause oxidation and rusting. Aluminum is highly conductive, meaning it transfers heat and cold. As a result, aluminum is less insulating than vinyl. Aluminum windows are pricier than vinyl windows, which may not fit every homeowner’s budget.

Vinyl is 46% to 67% less expensive than aluminum. On average, homeowners pay $250 to $600 per window for vinyl windows and $400 to $1,200 per window for aluminum windows. Homeowners could save up to $4,800 by choosing vinyl over aluminum to replace eight windows.

What are the benefits of aluminum windows?

Aluminum is very durable and can withstand extreme weather conditions. This material is versatile and comes in several colors and finishes. Aluminum is also environmentally friendly and can be recycled.

Which is better for insulation: aluminum or vinyl?

Between aluminum and vinyl windows, vinyl has more insulating properties, meaning it slows down the transfer of heat between the home and the outdoors. This can help homeowners save money on energy costs. However, some aluminum windows come with thermally improved options or thermal breaks.

What is the advantage of vinyl over aluminum?

Vinyl is more budget-friendly than aluminum regarding its up-front cost and long-term energy savings. Vinyl requires less upkeep and doesn’t need painting to maintain its appearance and functionality. This material is better suited for most homeowners, except those who live in hotter areas.
