Top casement sash or hopper sash!

In my neck of the woods (SE) casements are hinged and sashes slide,
and hopper lights are hinged on the bottom rail. The usual name is
top lights or fanlights.

Pete,

In my part of the country , they are as stated and just to add to the
confusion, are as you say. You can get them top hung, bottom hung, left
hand hung and right hand hung, but however they are fixed, they are a
casement sash (whether hopper, top light, side light et.al) and these are
fitted into casement frame.

Vertical sliding sashes (box frame sash) in this part of the country are
fitted into a box frame windod and have sash weights and sash cords fitted
to control their movement.
