PVC tends to be lighter than the thermal isolated aluminum we usually use. At least the stuff we have over here. (I work with steel and aluminum though. Never dealt extensively with PVC since it requires specific equipment).

Usually the problematic ones are the long “strip windows” (80cmx3 to 4 m) that some places use especially with argon filled glass panes (thick, layered double panes. With argon filling for emissivity. It may be what you have as well). But for them the style in the picture is usually set aside for a vasistas style closure. Which has an extra support for the panel. Paired with a pull string opening mechanism. I don’t know what’s the genetic name.
