Horizontal Bi-Fold Door System

Fold up glass wall system... creates its own canopy too!Funny that I just happened to run across this manufacturer of horizontal bi-fold doors on the Archinect forum since I was thinking about utilizing such a system for a project I am currently designing. Frank Jonkman & Sons is a manufacturer of greenhouse systems, but as they mention on their website, this horizontal bi-fold door system has amazing potential beyond greenhouse applications. The benefits of the system, other than the "cool" factor:
Requires no extra space within the adjacent walls for storing open panels
No track or threshold required at ground level
It can be easily installed in new or existing buildings
It is available in any width or height and the panels may combine virtually any combination of glazing materials
