The truth is, both materials offer a plethora of appreciated benefits of value to the home, whether it’s in terms of energy efficiency, security or style!

Despite uPVC still remaining one of the UK’s most popular window material largely thanks to their highly tempting affordability, aluminium has in recent years emerged as a more than worthy competitor, being modern, sleek and great for thermal efficiency.

For the longest time, uPVC has been seen as the material for domestic homeowners, whereas at the opposite end of the spectrum, aluminium has long been the commercial material of choice largely thanks to its inherent strength and ability to withstand large glass panes. In actual fact these invisible consumer boundaries are irrelevant, with aluminium presenting just as many benefits to the average homeowner as uPVC
