How to build a sliding wall section
I have overseen the install of, and eventually tuned up a set of sliders that were 5 sections of glass panels 8 ft each. 2 of the panels, one at each end, were stationary, the other 3 were operable. Each panel weighed about 500 lbs each with 1 3/4" thick insulated glass panels. The wood frame was about 3" thick. The hardware was lift-slide hardware The link is to the manufacturer that was used on this job, sorry the pic is crappy. It was shot from a long ways away.


The screen doors are in the way of the glass panels, but they are huge. 

The point is I am trying to make with this is you don't need to use a glass door to do this with, although you can. It could very easily be a full wood panel as well.

The pic below shows another door system I did install from scratch, but the only picture I have that really shows anything, shows the bottom track and the panels. There are 6 panels in this wall (a different job than the other pic) 2 stationary and 4 operable. These doors were much lighter.
