Verdict - Aluminium Windows vs Wooden Windows

Windows South Africa

In South Africa, where seasonal temperature fluctuations are much less extreme, opting for aluminium window frames is ideal. 

Aluminium is lightweight, yet strong. The robust and versatile quality of this material lends more freedom to the design. For example, you can have a variety of fame sizes without compromising strength and choose from a range of colours. 

Using aluminium window frames will also reduce future maintenance costs, which is why it’s adding value to homes even though it’s the cheaper option. It will also last 30 - 40 years when cared for properly. Contrary to wood, aluminium window frames will not warp or rust or rot.

Wood is often preferred as the eco-friendly option, but aluminium is 100% recyclable. In fact, the recycling of aluminium requires only 5% of the initial energy consumed to create it.

According to current real estate trends, Aluminium is the material of choice for windows and doors.

FAQ - Aluminium Windows vs Wooden Windows

What are the disadvantages of an aluminium framed window?

Poor insulation: Aluminium is an excellent thermal conductor of heat or cold. That means you might have to deal with condensation. When choosing your aluminium window frames, you may need to include Thermal Break Technology- which will, unfortunately, increase the cost.

Corrosion: If you're planning on building in a coastal area, aluminium window frames might be more susceptible to corrosion. You'll have to deal with removing salt residue on a very regular basis. We recommend adding an anti-corrosive coating onto the aluminium.

How much do aluminium windows cost in South Africa?

Excluding installation costs, the average price for a 1500 x 1500mm aluminium window is between R900 and R1600. The price will depend on where you live, supplier brand, glazing, size, design, colour and any additional finishes.

What is special about aluminium windows?

Aluminium windows are one of the most durable materials. Unlike wood or PVC, it won’t swell, crack, split, or warp over time.

How often do you need to replace windows?

A new, quality window should last between 30 and 40 years before you need to consider replacing it.
