Aluminium Windows Versus UPVC Double Glazed Windows

- Sep 07, 2017-

Considering getting aluminium windows? Why not consider UPVC double glazed windows instead? There are a number of differences between the 2 types of windows, find out more on why UPVC might be better for your home.

Energy Efficiency

UPVC have long been popular with home owners because of their energy efficiency. UPVC has a high thermal resistance providing an effective barrier between the inside and outside of your home. UPVC’s high thermal resistance helps save money on heating and cooling costs. In contrast, aluminum’s poor thermal resistance makes heating and cooling a house more expensive.


Aluminium is a highly resilient material but still needs maintenance every once in awhile. UPVC, on the other hand, never rots, flakes, rusts or fades, they require almost no maintenance except for the quick wipe with a cloth to keep it clean.  UPVC is one of the most durable of the material available, Aluminum is easy to bend and dent. As a result, if not carefully treated, aluminum windows get dents and lose their exact shape making it harder to open and shut the windows. Fully reinforced UPVC is tough and resilient making it highly unlikely that your UPVC windows will need to be changed – that is why Ecostar offers a comprehensive and unconditional 10 year warranty on all their products.


Because of the strength of fully reinforced UPVC double glazed windows, they are highly secure – their frames are constructed to the highest degree of hardness making it extremely difficult to break through or damage.  All of Ecostar’s double glazed windows are designed with security in mind and comes with an official police preferred security specification, Secured by Design.


Insulation is another feature of the UPVC material that surpasses aluminium. UPVC is a very competent insulator and provides the best energy and sound insulation. Not only does it improve energy efficiency, it also reduces intrusive external noise by up to 80%.
