Aluminium Bi-Fold Doors Vs uPVC Bi-Fold

If you’re considering installing large folding doors in your home, you’re probably wondering whether you should choose aluminium bi-fold doors or uPVC doors. Both materials can be used to make large concertina stacking doors, but which will be better for your home? We look at the pros and cons of both options.

What is uPVC?

uPVC stands for unplasticised Poly Vinyl Chloride. It is a durable and low maintenance option for creating window and door frames.

Aluminium vs uPVC – which is more durable?

While uPVC is a very durable material, it is not as durable as aluminium. uPVC folding doors will probably require replacement after 20 to 30 years. Aluminium folding sliding doors, on the other hand, can last up to 45 years. Aluminium doesn’t degrade like uPVC will. But both materials last longer than wooden door frames.

Which offers better efficiency?

Older uPVC windows and folding doors were terrible at insulation. They were draughty and wouldn’t keep heat in winter. But newer uPVC technology is better. New uPVC windows and doors have an internal profile that prevents heat loss and ensures energy efficiency.

Aluminium windows and folding doors are good at energy efficiency and will achieve the same levels as new uPVC. So, both options offer good thermal efficiency, as long as you are dealing with new materials. For ultimate enemy efficiency, consider using double glazed glass.

Which is more aesthetically pleasing?

Aluminium frames are more aesthetically pleasing than uPVC because they are sleeker and thinner, allowing for more glass, and therefore great views out into your garden. They also allow more natural light into your home, making it feel airier and more spacious.

uPVC frames, on the other hand, is normally plain white, and look like plastic. Some uPVC options can be coloured, but they still retain their plastic-like look.

When considering large folding sliding doors for your home, aluminium is the clear winner, showing off your garden and allowing more natural light into your home. Aluminium stacking doors are modern, sleek and beautiful, and can be stacked up to open up your home, allowing for true indoor-outdoor living.

Which offers better soundproofing?

uPVC offers better soundproofing when it comes to sound. uPVC is an efficient insulator and offers better soundproofing capability. If you live close to a busy road, you may want to consider uPVC as an option. But remember, that aluminium frames also offer sound insulation, and you can further enhance your sound insulation by installing thicker grass in the frames.

Which is easy to maintain?

Both uPVC and aluminium are very easy to maintain. In fact, there is very little that needs to be done to either once they’re installed. They are both easy to clean and can be wiped down with a damp cloth to remove any dust or dirt.

Which is more eco-friendly

PVC is not an eco-friendly material. It cannot be recycled as it often contains toxic materials like chlorine and heavy metals. Aluminium, on the other hand, can easily be recyclable and is therefore far more environmentally friendly than uPVC. Aluminium makes a great choice for people who are concerned about their carbon footprint.

Which is the best choice overall?


If you’re looking for an energy efficient option that looks great and is easy to maintain, aluminium folding doors and aluminium windows are the clear winner. Despite costing more than uPVC, the doors will last longer and look better, adding value to your home.
