We have the double pane sliders.
2014 had standard single-pane slider windows and optional double-pane sliders. Our 2014 had single-pane.
2018 had standard single-pane sliders, optional double-pane sliders, and optional thermal frameless (awning-style). Our 2018 has double-pane sliders. At the time, there were reliability issues with the frameless windows, so we went with the tried-and-true sliders.
Comparing single-pane and double-pane sliders, the double-pane insulate noticeably better, reduce more outside noise, and have less condensation. But they are heavier and cost more.
Someone more up-to-date will have to comment on the window options currently available.
