Are Aluminium bifold doors better than uPVC?

Both aluminium and uPVC doors are a great investment, however, when it comes to bifold doors, in particular, aluminium is the superior choice of material for 3 simple reasons…

1. Aesthetics

Aluminium frames offer slim sightlines and can hold larger panes of glass, which means fewer panels are required. So, aluminium bifold doors are perfect if you have picturesque views or want to allow a plethora of light into your home. uPVC frames, however, are bulkier and will not give you the trendy sleek aesthetic as they cannot accommodate large panes of glass like aluminium can.

2. Maintenance & durability

Aluminium is notoriously known for being incredibly strong and can last up to 40 years, making it an incredibly worthwhile purchase. In addition to their naturally robust properties, we powder coat our aluminium frames so they are completely scratch-resistant. You will only need to wipe them down occasionally and they will look brand new!

3. Flexibility

Aluminium is extremely flexible and gives you the freedom to create your perfect space! So, if you have a complex configuration in mind, this can be accommodated.
