Walls divide rooms but what do you call what divides stories?
Looking from below it would be the ceiling, looking from above it would be the floor. But when looking at it from the outside? Is there a common word?
I am looking for a word which describes structures that divide a space vertically as opposed to walls which divide the space horizontally.

Believe it or not, the word you are looking for is floor.
It refers to both the space between and the actual divisions. But the space between can have other names like story ("storey" in British English).
If it were a house it would be the roof.
I think you could use "floor slab" or deck.
