How much does an aluminum window cost?

When you’re shopping for new home windows, there are a lot of factors that go into the final cost. One of these is your choice of material.

Aluminum is a good choice for many homes because it’s strong, lightweight, and comes in a wide variety of colors. It’s also a more environmentally friendly product than vinyl.

Cost of Materials

If you are thinking about installing aluminum windows in your home, the cost will vary depending on a few factors. The window size, color choice and any hardware accessories you opt for will all impact the final price.

Generally, you can expect to spend between R3000 and R8000 fully installed for an aluminum window. However, this figure can be higher or lower for bay and multi-window assemblies and custom shapes.

For example, aluminum frame windows are often more expensive than vinyl frames, but they can offer a more aesthetic appeal. They also tend to be more durable and hold up better in harsh weather conditions, like hurricanes.

Another thing to consider when choosing an aluminum window is the thermal efficiency of the frame. Many aluminum frames today are thermally broken, which means they have non-conductive parts that are separate from the metal on the interior and exterior of the frame. This is an energy-saving feature and will be especially helpful if your home is located in a hot climate.

Cost of Installation

The cost of installing an aluminum window depends on the type and size of the windows, as well as the work required. It also varies by whether the windows are replacements or new.

For example, replacing a single-hung window on a brand-new home will typically cost less than replacing it on an older one. Older homes have to be reframed and sometimes refurbished to fit the new windows.

Often, the pros will need to remove and replace the trim in order to install the new aluminum frame. This additional labor and materials will add up to a larger bill.

Another factor that affects the cost of installation for an aluminum window is whether it is thermally broken or not. These models have a non-conductive material between the different pieces of aluminum in the frame to improve their energy efficiency.

Energy Efficiency

Aluminum windows are among the most energy efficient on the market. This is because they are able to retain a high level of heat and keep it inside the home.

They can also withstand the elements without rusting or warping and are much easier to maintain than wood frames. They also do not require any paint or polish and can be cleaned easily with a damp cloth.

However, it is important to note that aluminum is not a good insulator on its own. Therefore, you should make sure that your new windows are equipped with a thermal break in the frame.

In addition, the window should be insulated with low-e glass to keep out cold air in the winter and hot air in the summer. It is also recommended that you use a high-quality seal to minimise air leakage between the frame and the glass.


If you’re looking to get a new aluminum window, one of the best things you can do is to make sure it comes with a warranty. However, warranties are often complex documents with a lot of fine print and can be confusing to understand.

In general, warranties cover a variety of issues that can arise with a new window. Some of these include installation errors, glass breakage, and hardware defects.
