New UPVC windows & door - Which manufactures are better?

RobBoss

Now looking to replace some UPVC (or PVCu )  windows and have a large sliding 4 part patio door.
With the door, budget can't stretch to Aluminium, so if it is UPVC, would rather get better quality frame/wheels etc.
I am using local independents for quotes but I would like to know the better quality 'profiles' in other peoples experience.
So far...
Swift Frame - OK quality. (Norwich I believe)
Liniar - Windows ok, doors not so good?
Rehau - Keeps coming up as good quality on other forum research sliding doors are better too apparently?
Eurocell - On par with Rehau.
Thanks

Thanks.
Any other homeowners or fitters opinions please?

Any experience with Deceuninck sliding doors or Veka?

Local independent is fitting Rehau windows here. Quality is good, and the fitter is paying attention to the finer detail (which is more important than the frame). A good frame badly fitted is going to be worse than a well fitted "budget" frame (one only needs to look at some of the Anglian/Zeneth/Etc for proof).

Can't comment on doors as I haven't needed to replace mine (yet).
