While you might not have given it much thought in the past, choosing the right doors for your home is an important decision that affects everything from the aesthetic of your living spaces to the overall security and energy efficiency of the building. 


While there are many options to choose from, bi-fold doors have become an increasingly popular choice, seamlessly blending outdoor and indoor spaces, and providing lots of natural light. 


In this blog, we’ll explore the key differences between aluminium bi-fold doors and UPVC bi-fold doors, helping you to decide which best suits your home and lifestyle. 


What are the advantages of aluminium bi-fold doors?


Strength and durability


Aluminium is a robust material, making it an excellent choice for bi-fold doors. It can withstand various weather conditions, including heavy rain and strong winds. 


Slim frames 


Aluminium frames can be engineered to be very slim yet exceptionally strong. This means you get a larger glass area and unobstructed views when compared to UPVC doors. 


Aesthetic appeal


Aluminium bi-fold doors are known for their modern and sleek appearance. They can also be powder-coated in a wide range of colours, allowing you to customise them to complement the style of your home. 


Low maintenance 


Unlike wood and other materials, aluminium is a low-maintenance material. It doesn’t warp, rust, or corrode, meaning that you won’t have to worry about regular upkeep. A simple wide down with a damp cloth is usually all that’s required to keep them looking their best. 


Energy efficient 


High-performance aluminium door frames are fitted with thermal breaks that can act as a barrier to reduce heat transfer. This helps to keep your home warm in winter and cool in summer. 




The strength and durability of aluminium bi-fold doors make them ideal for exterior doors, providing an extra layer of security for your home. 


What are the advantages of UPVC bi-fold doors? 




UPVC bi-fold doors are generally more budget-friendly than costly alternatives, making them an excellent option for homeowners on a tighter budget. 




UPVC is a natural insulator, which means it can help to retain the heat inside your home, leading to reduced energy bills. 


Low maintenance 


Like aluminium, UPVC is low maintenance. It doesn’t require painting or sealing, and it won’t rot or corrode. A quick clean with soapy water is usually all that’s needed.


Customisable finishes 


While not as versatile as aluminium, UPVC bi-fold doors still come in a range of finishes, from white to grey and black. 


Choosing the right bi-fold doors for you


As you can see both materials have their advantages, and it’s important to weigh those against your individual needs such as your budget and the specific requirements of your home. 


Here are the three key factors to consider when making your choice: 




If cost is a concern, UPVC bi-fold doors may be the more affordable option, helping to enhance your living space without breaking the bank. However, if you don’t want to compromise on aesthetic appeal or durability, you may find aluminium bi-fold doors are worth the extra cost. 




Another factor that may affect your choice is the aesthetic you’re trying to achieve. If your home is a contemporary building, aluminium bi-fold doors can help you maintain that sleek, modern look. UPVC doors on the other hand can work well with traditional or more classic designs. 


Energy efficiency 


Energy efficiency is a top priority for every homeowner, and while both materials are great for thermal insulation, between the two, UPVC bi-fold doors are the best option.
