What Is Better Aluminium Or PVC

To help you understand and decide which of these materials is best for your home or commercial building, we will explain various aspects and features. We will also tell you how the aluminium and PVCu supply chains differ and where each material is best suited.

The “what is better, aluminium or pvc” debate has no real answer.  The decision process will largely depend on the information presented to you the customer that needs to be accurate and relevant. If you are presently in the market for replacement windows or new windows for your home extension, one of the things you may be considering is what is the best material – aluminium or PVCu/upvc.

If you are new to replacement windows, much of what you will find out depends on how it’s presented to you. You may do your own research or seek help from a double glazing firm. Therefore it is vital that you are given with the right information online, in brochures or by a double glazing salesman

Choosing Between Aluminium Or PVCu And Why It Matters.

The home improvement industry is diverse, multi-tiered and multi-faceted.  Unlike other consumer products, information on windows and doors is broad ranging.  For many years we relied on the information given to us by showrooms and double glazing salespeople.  Often these sales messages were biased towards selling us any window, not the right window.  As a result, many people were sold PVCu thinking it was the only option or the best option.

Much of the dominance of PVCu came about because the vast majority of home improvement companies only sold plastic and never offered aluminium. Additionally, early generation aluminium products when compared to PVCu simply weren’t as affordable or as appealing.  This is no longer the case today.

Today, thanks to the internet, a different marketing approach and more professional industry, homeowners are better informed and products more transparent.   There are also more aluminium providers than before.  Aluminium windows and doors are as thermally efficient, as secure and with some brands, also very affordable.

Products Available In PVCu And Aluminium.

For many years, PVCu was the dominant material for residential windows. As the table below shows, PVCu predominantly focused on residential windows and doors where aluminium concentrated on commercial buildings and high-value residential work.

As a result of the substantial investment in products and design, you have never had as much choice in windows and doors as you do today. Modern windows and doors serve virtually every design and customer requirement.

The People Behind Aluminium And PVCu Windows And Doors.

One of the differences between PVCu and aluminium windows is the supply chain. Both aluminium and PVCu products are designed, tested and brought to market by systems companies.   The network of manufacturers then make the windows and supply them to the consumer as follows:

  • Trade Manufacturers supplying installers only.
  • Manufacturers that also install direct such as Anglian, Everest, Safestyle and others.
  • Trade counters supplying buildings and home improvement companies.
  • Installers buying in ready-made windows and doors.

Therefore as a homeowner, your new windows will come from one of these sources. PVCu windows and door manufacturers are substantially bigger businesses than aluminium manufacturers.  There are companies set up to produce thousands of windows a week. As a result of these ‘super fabricators,’ many of the smaller plastic manufacturers have ceased making windows, finding it much cheaper to buy them in.

We believe our website to the only one of its kind covering all the major systems and helping you understand aluminium doors and windows for homes and commercial buildings.  In the construction sector organisations such as the Council For Aluminium in Building work with Government and the entire supply chain. Many of the best aluminium providers, material suppliers and related business are members.

Understanding Where Aluminium Windows Come From.

The aluminium supply chain is much smaller.  Super fabricators of aluminium do not exist although substantial manufacturers are supplying the trade.  The main reason for this is the more hand-made nature of aluminium windows and that they now often come in so many colours.

Therefore when comparing aluminium or PVCu windows, you are arguably getting a more bespoke product with aluminium from a more short supply chain.  There are also many smaller manufacturers of aluminium as well.

Because aluminium windows and doors are today such a favourite material, colour choices are better and lead times significantly reduced.

Where previously PVCu sold on its ready availability, it is now possible to get white, grey or black aluminium windows as fast as you can get PVCu.

How Double Glazing Is Sold To You, The Consumer.

Much of what you read or hear about aluminium and PVCu windows will largely depend on the window firm and the double glazing salesman. There are many websites to be found comparing the various window materials but, many of these still provide incorrect information about aluminium as well as pvcu.

A company that only specialises in pvcu windows may discredit another product citing reasons why it should not be considered. A company that is experienced in all door and window materials will be able to give accurate and balanced information about the advantages and disadvantages of each and its suitability for your home, individual requirements and budget.

The reality is that most professional window companies will offer you a choice of materials.  However, a professional window company will admit to not offering a product rather than trying to discredit it.

Some things you may be told from those wanting to steer you towards PVCu windows include:

  • That aluminium windows condensate
  • Aluminium doors and windows are only used commercially
  • You need to constantly maintain aluminium windows
  • Aluminium windows are not energy efficient
  • Externally beaded aluminium windows are not secure
  • Aluminium windows need hardwood subframes.

If you hear any of the above as part of a sales pitch, we recommend you seek an alternative window company to quote for your new windows and doors.

Quality Differences Between Aluminium And PVCu.

Homeowners contact us with questions asking what is the best aluminium window or what products to avoid.  There is no bad aluminium window on the market.  If you’ve ever had issues with a double glazing firm before, bad manufacturing and bad installation is usually the cause.  Systems companies do not design sub-standard or bad products. The investment that goes into making sure all windows and doors are fit-for-purpose is substantial.

Aluminium and PVCu systems companies invest substantial sums of money in designing and bringing to market a suite of windows and doors.  These are accompanied by substantial technical and fabrication manuals.  In addition, systems companies assist their fabricators with tooling, training and product support.  Furthermore, aluminium windows today all meet or exceed established industry standards for quality, weather performance and security.

Therefore, it is not the aluminium or PVCu system that is ‘bad’. It is errors and not following the procedures set down by the designers.

Both aluminium and PVCu windows will be fitted with the correct specification glass, fit for purpose hardware and will carry their respective guarantees for manufacturing, installation, colour fastness and general finish.

Quality PVCu windows come with many different features such as timber look mitres or authentic period features on sash windows.  Whilst aluminium isn’t as good on these kinds of features yet, what it can provide is better mitres and joints compared to a basic welded PVCu corner.  The welded corners on pvcu windows can at times look unsightly and inconsistent.  Where reverse butt welds are used on PVCu windows to join the mullions and transoms, you will often see a cruciform where the two or three components are welded together.  Mechanical joints are available on PVCu windows, but the majority choose the welded option.

Where PVCu Windows Are Better Than Aluminium

You are reading this article on an aluminium website, but that does not mean that we do not possess knowledge of where PVCu windows can, in fact, be better than aluminium.

The PVCu replacement window market is diverse with a wide variety of products in the marketplace. There are a number of areas where PVCu can provide the better product for specific aesthetic reasons. Therefore if your property has a requirement for any of the following products the PVCu option may be better. Such products include:

  • Sash Windows
  • Timber Windows
  • Panelled Entrance Doors
  • Windows with the aesthetics of traditional wood windows.

For these products, there are plenty of aluminium alternatives.  However it is fair to say aesthetically for traditional looking windows, PVCu lends itself better where things like run through sash horns, antique or period looking hardware on sash windows, corners replicating the joints on traditional wood joinery and moulded panels on doors.

Where PVCu Windows Are Better Than Aluminium

There are a great many excellent window companies that specialise in selling both PVCu and aluminium windows, and they do this brilliantly.  Speak to most of these window companies and cost issue aside, it is aesthetics that generally convince a customer to go with aluminium over pvcu.

There is no doubt that the customer will always prefer the slimmer sight lines of aluminium.  Presented with the correct facts about both products again, price issue aside, the customer will usually choose aluminium.

However, for specific products such as contemporary frameless glazing, slimline sliding doors or Crittall® style and steel replacement systems nothing compares to aluminium or can beat it. For steel-look windows, the authentic Crittall® window is always the best choice.  For a cheaper product (although nothing like the real steel product) aluminium provides a lower-cost option.

How Much Does Aluminium Cost Compared To PVCu?

Our research shows that the cost of an aluminium window should be no more than 50% to 65% more than PVCu.

We get reports of price differences of over 100% and sometimes even up to 200%.  If your quotation is expensive, contact us for help.  We can put you in touch with companies that can offer aluminium windows at the realistic market rates.

It is very important to remember that the price points of PVCu windows vary substantially.  There are very cheap PVCu windows on the market which when compared next to aluminium will make the latter seem much more expensive.  Similarly, there are upper market PVCu windows of exceptional quality that will make the difference seem much less.  Therefore, if your quotes are expensive against PVCu ensure you understand the differences.

Summary

The great thing about the current market when choosing between aluminium or PVCu is quality and standards. Security, product guarantees, product quality and longevity, apply to both materials. There are no substandard products on the market.  Correctly made and properly fitted, both materials will be reliable and dependable.

If you are looking to buy new windows for your home, these five factors will probably influence your decision.

  • Cost
  • Energy efficiency
  • Security
  • Aesthetics
  • Quality.

Better suited to standard and less harsh environments

Therefore both aluminium and PVCu windows and doors serve the market well and will generally meet most customer requirements. However, each product as you can see offers its own set of features and characteristics.

Professionals like architects and the discerning customer consider aluminium superior to PVCu.  Both aluminium and PVCu products today are excellent and have their place in the market.  Ultimately the customer chooses what they like and what they can afford.  But it is important to have the accurate and correct information from an unbiased window company if you are considering both materials.

    The example about the mattress sizing page you mentioned in the last WBF can be a perfect example of new keywords and content, and broadening the funnel as well. I can only imagine the sale numbers if that was the site of a mattress selling company.
