uPVC 4 pane — what it is
Two-pane sliders give you half the opening. Four-pane sliders on a triple track give you three quarters, because three panes stack behind one. Aluminium takes the biggest panes; uPVC is the value option and perfectly sound at ordinary domestic sizes.This page shows only the upvc 4 pane designs.

Questions
How much of the opening actually opens?
About half on a standard two-pane slider, because one pane slides behind the other. A four-pane triple track gets you to roughly three quarters. If you want more than that, you want a bi-fold.
Are sliding doors secure?
Modern ones are. The things that matter are multipoint hook locks that engage into the frame, anti-lift blocks so the pane cannot be jacked off its track, and laminated glass if the door is out of sight from the road.
Aluminium or uPVC for a slider?
Aluminium if the panes are large or you want slim sightlines — it is stiffer, so it carries big glass without deflecting. uPVC is the value choice and fine at normal domestic widths.
