The top 5 myths About Aluminium Windows.

If you are about to start a renovation project or looking to change your windows and doors then there are many reasons to consider aluminium for your replacements.  Modern aluminium windows and doors offer several advantages, such as:

  • High security
  • Very slim sightlines
  • Excellent thermal performance
  • A choice of traditional or contemporary appearance
  • Aluminium windows are suitable for any kind of home

However, despite the advantages of aluminium many window companies prefer to sell uPVC windows.  Partly because uPVC is the product with greater margins or the one that the company is more comfortable selling.

Saying that there are also companies that happily sell PVCu, aluminium and timber windows alongside each other.  They have the confidence, the experience and the product knowledge to explain the differences between the various materials and help you reach an informed choice on what will be the best for your home and your budget.

What are the myths about aluminium windows?

If you are getting quotations from any window company and they attempt to dissuade you from buying aluminium windows or doors in any way at all, then this should flag up a warning that they are biased towards an alternative product.  If you ask the question of your typical home improvement firm, “what about aluminium?” there should be factual and accurate information about them.

Every window and door has its place in the market and is fit for purpose.  Therefore no window company should attempt to rubbish a product in any way at all.

Here are our top five “myths” that you may hear about aluminium windows.

1. Aluminium Windows Condensate

This is simply no longer the case.  As modern PVCu windows have had major advances in their thermal performance over the years, so has aluminium! No window can ever eliminate condensation nor should any window company tell you that they will.  There are many reasons why windows condensate.

Aluminium windows today can achieve the same and even lower U values than PVCu or timber windows.  It is all down to product, design, window and glass specification.

2. Aluminium Windows Require Hardwood Subframes.

It is true that some aluminium windows are fitted to existing or new hardwood subframes.  However this does not mean that if you already have wood frames in your house they need to remain.

There are countless “direct fix” window systems available today that were specifically designed to replace existing hardwood subframes.

However if the hardwood surrounds around your windows are a feature of your home, it makes perfect sense to retain them.  There are also countless window systems designed to fit into hardwood frames, stone frames or stone mullions.

3. Aluminium Windows are externally beaded and therefore less secure.

This is arguably the worst myth surrounding the security of aluminium windows.  With sophisticated testing institutes such as Secured by Design, British or European standards surrounding window security and other performance standards if an externally beaded window has passed these tests (and most have) then they are secure.

Modern technology and window design now enables externally beaded windows were the beads cannot possibly be removed from the outside without internal gaskets being removed first and external window beads lock securely into the window through simple engineering and great design.

However if you remain unconvinced, aluminium windows are available externally or internally beaded.

4. Aluminium Windows are more than twice the price of PVCu

The pricing of windows is a subjective matter given the wide range of offers, discounts and reasons to buy within the double glazing industry.  There are many companies that choose to up sell aluminium windows as some kind of premium over PVCu.

By comparison, window companies that specialise in aluminium sell windows and doors as standard products not as premium windows or reasons to up sell.

Aluminium windows will cost you more but the quality to cost ratio is good value when you consider what goes into making an aluminium window and that a metal as a raw material will invariably be more expensive than a plastic.

The price of your aluminium windows will depend on many factors such as:

  • Where does your company buy them from?
  • How experienced are they at them?
  • Is aluminium their standard product or an upgrade?
  • Do they want you to buy PVCu as they know the product better and the margins are greater?
  • Some PVCu windows are very cheap indeed  and this can make the additional cost of aluminium even greater.

If you are receiving quotations for aluminium windows and the markups over PVCu are substantial, contact us for recommendations on other firms to consider local to you.

5. Aluminium Windows are only used commercially

Aluminium windows have been used commercially for well over 30 years now because the advantages of slim lines, high performance, durable polyester powder coatings and high strength have been appreciated by architects for decades.

Aluminium window and door sales have been growing year on year for the last 10 years or more whereas PVCu sales have been declining.  One only needs to look at the sheer popularity of aluminium bifolding doors and the dominance of aluminium products on home renovation shows to realise homeowners are discovering the advantages of aluminium windows.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted. I can reinforce the many positive reviews posted so far, Nick was very quick to respond, providing comprehensive detail, with excellent independent advice.In summary, great service, thank you Nick.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
