Prime Bi-folds selection of Bi-folding doors all use an aluminium frame.  
The reason for this is because we find the other two potential materials, wood and UPVC, to be less viable than aluminium.  
UPVC is perfectly fine for smaller windows and doors, however, due to the size of Bi-folding doors the strength of UPVC is tested to it's maximum and with heat variation the door can become unpredictable and unreliable. UPVC doors will often be less expensive than Aluminium doors, however, the Aluminium doors will often show their value in reliability and be much more cost effective. 
Wood is a very good natural material and can give great character to your door, however, due to wood absorbing moisture the door frames can be warped which can lead to the door becoming unreliable and poor gasket seal performance. To prevent these issues you will need to have a continuous maintenance schedule which can be expensive. 
Aluminium is lightweight and strong which allows aluminium framed doors to be narrower than Wood and UPVC while also being more resistant to flex and contraction with heat variation. Aluminium is also a good choice of frame due to the possibilities it provides in terms of finishes including wood grained finishes along with being possible to have a finish in any colour you can imagine. 
Prime Bi-Folds supply and fit Aluminium framed Bi-folding doors throughout Devon and the surrounding areas.
