What Are Vinyl Windows?

Additionally, vinyl windows require minimal maintenance as they do not need to be stained or painted, unlike traditional wood windows. [1]

What Are Aluminum Windows?

Consider using aluminum windows for your home as they are both efficient and cost-effective. They provide excellent insulation and durability, making them an ideal option for homeowners who want to save money on energy costs. Aluminum frames are made from a lightweight but strong alloy of aluminum and other metals that resist corrosion and rusting, making them a great choice in areas with high humidity or near the ocean. These frames also come in a variety of colors to match any decor scheme.

Vinyl vs. Aluminum Windows


Vinyl windows are sleek and smooth, offering a modern look to any space. Aluminum windows, on the other hand, create an industrial or commercial aesthetic with their straight lines and sharp edges.


When comparing aluminum and vinyl windows, it is crucial to consider their durability as one of the main factors. Aluminum frames are often applauded for their strength and durability – especially in comparison to wood or vinyl frames. Because aluminum is a strong material, it does not deform easily under pressure, making it ideal for windows that need extra support or insulation. Additionally, aluminum frames have great resistance to rot and rust, meaning they can withstand extreme weather conditions without degrading over time. On the other hand, vinyl frames offer excellent protection against cold air infiltration and corrosion-resistant properties. Vinyl window frames are also less susceptible to warping due to temperature changes than aluminum frames.

Ongoing Maintenance

Another important factor to consider when choosing between aluminum and vinyl windows is the amount of ongoing maintenance required. Aluminum frames require regular painting or refinishing in order to maintain their appearance, whereas vinyl frames are usually maintenance free.

Ongoing Maintenance

Vinyl window frames also come with a protective UV coating that prevents fading over time, meaning they need very little upkeep compared to their aluminum counterparts. Additionally, because vinyl windows have fewer moving parts than most aluminum frames, there is less possibility of problems occurring due to wear and tear.


Aluminum windows are not known as a highly energy-efficient material. They do not insulate well, which means that in cold climates, warm air can escape through them and cool air can enter. Vinyl windows, on the other hand, are much better at keeping air from entering or escaping your home.

This helps to keep your home more comfortable year-round and keeps energy costs low.
Additionally, vinyl is recyclable, an important environmental consideration when choosing materials for your windows. In terms of energy efficiency, vinyl wins over aluminum every time. [2]


The cost of aluminum and vinyl windows is roughly the same. The price will depend on factors such as size, style, and the quality of window you choose. However, in terms of bang for your buck, vinyl is a better choice. It requires very little maintenance over its lifetime and can help to reduce energy bills due to its superior insulation properties.


Installing aluminum windows can often be more labor intensive than vinyl, as the former requires welding and cutting. Vinyl frames come pre-sized and are easy to fit into existing openings without any additional framing needed. All that’s required is to fasten the window frame with screws or nails. This makes installation of vinyl windows much quicker, saving on both time and installation costs.

Environmental considerations

Aluminum is recyclable, so when it comes time to get rid of it, aluminum can be recycled and used in other products. Vinyl windows cannot be recycled and will end up in a landfill once they’ve outlived their usefulness. If environmental impact is an important factor for you, then aluminum is the clear choice.


Vinyl windows are more popular these days because they’re cheaper, easier to install, and provide a more energy-efficient seal than aluminum. While aluminum windows have their advantages in terms of strength and durability, most people opt for vinyl window frames when it comes to replacing old windows or installing new ones.

Popular Brands

Popular brands for vinyl windows include Andersen, Pella, and Marvin. Aluminum window frames are often found in low-end models from off-brand companies. When it comes to the best of both worlds, you can’t go wrong with a hybrid model that combines both aluminum and vinyl materials.


When comparing the insulation properties of aluminum and vinyl windows, vinyl is the clear winner. Vinyl windows are much more energy efficient than aluminum, providing a better barrier against heat transfer. This can help keep your home warmer in winter and cooler in summer, reducing your heating and cooling bills while improving comfort levels all year round. Aluminum windows offer some insulation value, but not as much as their vinyl counterparts.


In addition to improved insulation values, vinyl windows also tend to have tighter seals than aluminum frames, resulting in less air leakage around the window perimeter. This means you’ll save even more on energy costs by choosing vinyl over aluminum. Ultimately, if you prioritize insulation when making your window decisions, vinyl is likely the best choice for you.
