The Pros and Cons of Aluminium and uPVC Doors

Aluminium or uPVC: it’s the question we all must face when looking to spruce up our home with some bi-fold doors. You’ve heard your father-in-law talk about being pro-aluminium while your neighbour just got some new uPVC bi-fold doors and has been showing them off when you nip over to collect your parcels. 

Needless to say, everyone has an opinion about whether they prefer aluminium bi-folds or uPVC bi-folds. Struggling to choose between the two? Never fear; we’re here to help make your choice easier. Each material has its own unique pros and cons, so let’s take a look at them.

How long do aluminium and uPVC doors last?

It’s the number one question we get asked: which one lasts longer? To be honest, it really depends on many factors, from how your aluminium and uPVC doors are installed to general upkeep vs normal wear-and-tear. Both aluminium and uPVC are extremely weather-resistant; they’re like the superheroes of the bi-fold door world, so even in extreme temperatures, they’ll still hold up really well. uPVC has been known to last for up to 10 to 35 years, while aluminium only just beats this by making it up to 45 years. 

How do I maintain my aluminium and uPVC bi-fold doors?

General everyday upkeep and maintenance for aluminium and uPVC bi-fold doors are pretty minimal. Generally, keeping your bi-fold doors looking pristine just involves giving them a quick wipe over to prevent superficial stains from the elements. uPVC bi-fold doors may need their locks oiling now and then, but that’s really about it for any maintenance issues! 

Neither material experiences any warping or aesthetic alterations that are commonly associated with wood or timber. Both materials hold up well against the elements: uPVC is weather-resistant and non-porous, while the polyamide properties of aluminium bi-fold doors, alongside its clear coat of aluminium oxide, fight against any weather corrosion. 

Aluminium’s polyamide technology will also maintain its appearance so your bi-fold doors can stand the test of time. One thing is certain: both materials are made of the tough stuff to go the distance!

Are aluminium and uPVC bi-fold doors eco friendly? What about family and pet friendly?

We’re all trying to live more sustainably and ensure that our home impacts the environment as little as possible. One of the massive pros for both uPVC and aluminium is that they can be recycled at the end of their lifespan. Around 70% of aluminium has been recycled and reused, while uPVC can be recycled up to 10 times before decomposing. 

While uPVC is made using oil, aluminium is a little bit greener due to its manufacturing process and the fact that it doesn’t burn. uPVC, on the other hand, if burned at a high temperature, has a slight chance that it could release dioxins that are harmful to the environment. Luckily uPVC only burns at the ludicrously high temperature of 391 degrees Celsius, so it’s absolutely fine during the summer and, of course, when you’re busting out the BBQ. 

Like with any material, we advise people to dispose of their uPVC securely and safely. Both uPVC and aluminium are heavily regulated materials that are perfectly safe around pets and children.

Will aluminium or uPVC bi-fold doors add more value to my property?

Whether you’ve only just reached your first step on the property ladder or if you’re a veteran of the property market, your home is a nice nest egg that you can decorate to increase its value. Without a doubt, aluminium bi-fold doors will achieve this as they are more expensive to install and boast a longer lifespan. Particularly if your home is a period property and has vintage character, aluminium will add more stability, durability and value to its price.

Are uPVC and aluminium thin enough for bi-fold doors? 

Aluminium is thinner than uPVC, so it can handle large panes of glass for your windows that will let more light in. However, the thickness of uPVC allows it to hide potential imperfections like sealant and paint, so they’re a fantastic option for roof lanterns, sash windows and French doors, as well as bi-fold doors. 

Our final thoughts on bi-fold doors

Both uPVC and aluminium are fantastic long-lasting options for bi-fold doors that require very little upkeep long term. Factors to consider when choosing between uPVC or aluminium for your bi-fold doors include your budget, your property’s design and whether you intend to re-sell your property later on. uPVC is a cheaper option for renovations or rented properties that is just as durable as aluminium, while aluminium lasts that little bit longer and is usually popular with property ladder climbers.
