uPVC, or to give its full name; unplasticised Poly Vinyl Chloride, has been a widely used window material in the industry since the 1980s. Tough, resistant to rot, and requiring very little maintenance, uPVC windows have been a popular choice with many homeowners.

The ultimate modern window material, aluminium combines high aesthetics with incredibly high performance, creating a window suited to the demands of a range of properties. Aluminium windows have experienced a surge of popularity in recent years, thanks to their use in home improvement television shows such as Grand Designs. No longer just for commercial buildings, domestic aluminium windows are perfect for adding a touch of modern elegance to a property.

What is the difference between aluminium and upvc windows?

There are obviously many differences between the two materials, each having their own individual benefits whilst surprisingly having a little crossover too! Here are 6 differences which help outline things you may want to consider:

uPVC windows vs aluminium windows price comparison

First thing’s first, let’s get rid of the elephant in the room. Aluminium is nearly always much more expensive to install compared to typical uPVC. This is largely a result of manufacturing costs which installers, unfortunately, have to compensate for.Due to uPVC spike in mass popularity since the 1980’s, demand makes it a much more affordable product. Aluminium may one day match British uPVC demand, but for the time being it remains the most expensive of the two materials.

Which material is more durable, uPVC or aluminium?

Although most uPVC windows typically have a long life span, the frames have the potential to degrade over many years. Aluminium on the other hand is a much more robust material for use as a window frame. With proper care it can be fitted to last almost infinitely, whilst being fairly low maintenance.

How energy efficient is aluminium double glazing vs uPVC double glazing?

It's actually the law for any newly installed window to achieve an energy rating of at least a 'C' in Window Energy Ratings (WER). Thankfully any window supplied by us achieves an A+ BRFC rating to result in the ultimate energy efficiency.Whilst many original uPVC windows fitted in houses today have the unfortunate reputation of being terrible thermal insulators, modern uPVC is quite the opposite. Contemporary uPVC now makes use of a complex internal profile which maximises thermal retention.Aluminium windows can achieve the same levels of energy efficiency. Thanks to an innovative polyamide thermal break, aluminium windows are equally thermal retentive to keep any home warmer for longer. Aluminium or uPVC – you can't go far wrong when looking for energy efficiency.


When choosing what kind of window frame to pick for your home, it's ideal to have one that can increase the beauty of both the inside and outside of your home. Never feel bad for considering style as well as function, aesthetically pleasing windows can even add value to your home!Thanks to their incredibly sleek sightlines, aluminium frames make for some incredibly views of the outside from the inside of the house. Despite these slim profiles that they are capable of holding larger glass panes thanks to their strong durability, enhancing the amount of natural light that enters your home.Aesthetic prowess is unfortunately the downfall of uPVC. In many people's eyes it gives off a simple, white plastic look that is ar from attractive, with some homeowners feeling that these frames are too plain. Both materials can however be coloured to your liking thanks to an extensive range of RAL colours. In terms of visuals however, aluminium wins every time.

Sound Proofing

One way in which uPVC does trump aluminium, is in its insulation capability. uPVC was originally designed to be a competent insulator and as such, provides the best sound proofing capability for homeowners who live in a busy built up area. Despite both frames being able to be double or even triple glazed, compared to aluminium, uPVC's capability to keep out sound is sometimes a reason for its popularity.

Ease of maintenance

Homeowners are always looking for a window that they don't have to spend time worrying about. It's understandable, these are the best kind. Dated windows (uPVC or otherwise) often need attention – replacement windows from Yatai change all that!uPVC is undoubtedly the best option if you want a material that is easy to maintain. Thanks to the high quality plasticised material, they are continually easy to clean and just require a simple wipe-down with a cloth, if ever they get dirty.Equally impressive, aluminium windows are incredibly robust which makes them resistant to corrosion and are completely weatherproof. This enables them to look as good as the day they were installed, never rotting or warping. 

Which should you choose? – Every homeowner is different!
