I'm looking to install some bifold windows
We get some pretty strong winds in the area, sometimes out of nowhere.
The size of window I'm after 1800w*1200h lends itself to a 3panel bifold, or a 4 panel is available slightly wider
I'm concerned the three panel bifold will have one of the panels flapping in the wind when opened, this is not a problem for a four panel as the ends are secured to the sill.
Is this likely to be a problem?

Four panel when fully open /\/\
Panels fold from left to right, sill is at the bottom
Do 4 panels work better if I only want to crack the window open slightly, it looks like it's way less fiddly to partially open the 4 panel as you only need to move the two leftmost panels, but on a three leaf you need to open the two rightmost panels and slide the leftmost panel across
