If the wall is made of a wooden frame covered with plasterboard or some other thin board, it is a technically a stud wall. These walls are commonly called (room-) dividers, dividing walls, and partition walls [i.e. based on what they are used for as opposed to how they are constructed]
I agree about your "stud"- type of wall - the thing that was putting me off was the term: "
thick wooden walls" in the OP - I've not come across the term previously and initially assumed that your term "stud" referred to fastenings.
On checking via the Free Dictionary:
studs - definition of studs by the Free Online Dictionary, Thesaurus and Encyclopedia. it gives:
(Miscellaneous Technologies / Building)
Building trades: A vertical member made of timber, steel, etc., that is used with others to construct the framework of a wall (BrE) and
An upright post in the framework of a wall for supporting sheets of lath, wallboard, or similar material (AME).

I would normally have regarded "room dividers" as being "part-height" temporary partitions or folding screens, but some hotels do use full height folding (concertina)
walls to temporarily divide up conference rooms to make multiple smaller meeting rooms.
