From energy ratings, to window tinting and hinges, with PVC Windows Australia your windows can be customised to suit any lifestyle and location.

However, the most important (and often overlooked) aspect of the window consideration process is its very foundation. The material your window frames are made of has the ability to make or break its overall effectiveness. Since you’ll be using your window frames for decades to come, choosing the right frames is one of the most important decisions you’ll make as a homeowner.

To lend a helping hand, we’ve come up with a handy guide to help you understand the differences between uPVC window frames and Aluminium window frames

What is a uPVC window frame?
First things first, what does uPVC even mean? uPVC stands for Unplasticised PolyVinyl Chloride. That’s a technical way of saying it’s a strong, stiff and durable plastic that’s proven to offer superior performance and durability – even in the face of extreme weather. uPVC is also 100% recyclable and can be recycled up to 5 times!
Double glazed uPVC window frames provide the highest level of thermal insulation and sound insulation. They’re perfect for keeping your home cool during sweltering Australian summers and trapping warmth inside during freezing arctic winters! They’re also known for their improved noise cancelling properties to help bring back a sense of peace and quiet to your home.
uPVC window frames are proven to last for more than 25 years when properly maintained. They’re also UV stable meaning they won’t succumb to the heat pressures of Australian summers. No warps, no cracks.
uPVC window frames require very little, or no maintenance. They won’t rust, rot or corrode after weathering and only require some soapy, warm water to keep them sparklingly clean!
uPVC window frames are far more affordable than high quality aluminium window frames. Their superior energy efficiency rating will also cut down your energy bill, making you save more money in the long run
What is an Aluminium Window Frame?
Aluminium window frames are (unsurprisingly) made from aluminium, and are the most commonly used window frame material in Australia. They’re championed for their durability but require higher levels of maintenance, and lower levels of thermal and sound insulation that uPVC window frames
Because it’s a metal, aluminium has a high level of heat conductivity, which can be counterproductive when trying to keep your home cool during summer months. This means that aluminium window frames are good at storing heat, and transferring it into your home. They’re also typically not as airtight as uPVC window frames and can lead to drafts and lack of heat retention during winter.
Aluminium window frames are known for their durability. However, if not properly coated or maintained, they’re often susceptible to rust, erosion and weathering.
Aluminium window frames require high levels of maintenance, cleaning and coating in order to deter rust, and keep them functioning like new. They can also produce condensation during colder months making them more likely to suffer from build-ups of mould and mildew, ultimately threatening their durability.
Aluminium is a more expensive window frame material in Australia. It is often expensive to manufacture, making it more costly for buyers.
