Why aluminium windows are better than uPVC?

When it comes to choosing windows for your home, there are two main materials to consider: aluminium and uPVC. Both materials have their own advantages and disadvantages, but in this blog post, we’ll explain why aluminium windows are the better choice for most homeowners.


Aluminium is a strong and lightweight metal that can withstand harsh weather conditions and resist corrosion. This makes it much more durable than uPVC, which is made of plastic and can warp, crack, or fade over time. Aluminium windows can last for decades without losing their shape or colour, while uPVC windows may need to be replaced after 10 to 20 years.


Aluminium windows also have a sleek and modern look that can suit any style of architecture. They’re available in a wide range of colours and finishes, and can be customized to fit any size or shape of window. Aluminium windows can also have thinner frames than uPVC windows, which means more glass area and more natural light. uPVC windows, on the other hand, have a more bulky and plastic appearance that can look cheap or outdated.

Energy Efficiency

Aluminium windows are also more energy efficient than uPVC windows. This is because aluminium has better thermal performance and insulation. Aluminium frames can be fitted with double or triple glazing, which can reduce heat loss and noise pollution. Aluminium windows can also have a low-emissivity coating, which reflects heat back into the room and lowers the heating bills. uPVC windows, while also having double or triple glazing options, have lower thermal conductivity and can allow more heat to escape through the frames.


Aluminium windows are also easier to maintain than uPVC windows. They can be wiped with a damp cloth and a mild detergent, and do not need painting or sealing. Aluminium windows are also resistant to pests, mould, and rot, which can damage uPVC windows. uPVC windows need more frequent cleaning and may need special products to remove stains or dirt. uPVC windows may also need to be repainted or repaired if they get scratched or damaged.

As you can see, aluminium windows have many advantages over uPVC windows. They’re more durable, energy efficient, and easier to maintain. If you’re looking for windows that will last for years to come and improve the look and comfort of your home, aluminium is the way to go.
