Three panel sliders are simply windows with three panels of glass,
where one or more of the panels is made to slide. There are five standard versions of
this type of window. Assuming that the window is viewed from the inside, and looking at the glasses from left to right, these types are:
Fixed / Slider / Fixed
Slider / Fixed / Slider
Slider / Slider / Fixed
Fixed / Slider / Slider
The standard sliding window catches - the flap catch, KLT catch, slam catch and push-button catch, can be accommodated, although careful consideration needs to be taken for windows where the centre glass slides.
