bi-fold doors

[ashdene]

I will soon be needing a set of 3.6 metre wide Bi-Fold doors as well as 2 sets of 1500mm wide french doors and a 1200mm wide window.
The french doors and the window are all off the shelf items but they will need to match the Bi-folds, which is where Im after some advice:

They will be going in my self-Build bungalow extension but im not sure where to start and who to use to supply these, price is a big concern but quality and durability is a major concern too.

Aluminium or UPVC?? would prefer UPVC as they are easy to match up to french doors and window etc...
Dont want them falling out the wall and crushing the wife (Not just yet anyway)

Any help would be great Thankyou

What shelf are the windows and doors coming from? If wickes the bi folds will need to be sheild profile

I will probably use the wickes ones as they have done me well in the past, but to be honest id rather get the bifolds right and then chose windowes to match

We fitted a new set of synseal bi folds a few weeks ago and they was not bad.
Aluminium are the way to go but pricey. Go upvc bi folds and integral blinds
