Aluminium windows and doors have gone through a major refresh over over the last few years. They were certainly not very popular with the residential market. Commercially aluminium has always been a number one choice. Yet it is commercial, industrial features that has been one of the reasons for aluminium’s rise... When it comes to bi-fold doors (which has also exploded within the last 10 years) PVCu has declined. Probably for good reason. Aluminium is stronger and gives a smooth finish. Alminium windows/doors can be powder-coated in a number of different finishes too.
That’s not to say there are no good PVCu bi-fold door products out there. But we can't deny that we haven’t had more leads in the Gloucestershire area for aluminium bi-folds than PVCu ones.
