Hi, do locks on wooden fire doors from flats going to the stairwell need to be thumb turn ?

if so what type are suitable for wooden doors ?

also if one separate flat has its own Upvc exit door going directly outside does that need to be thumb turn ?

 Thanks 

All fire exit doors, fire resistant or not, require to be be easily opened without the need of a key and a thumb turn meets that requirement also does other types of locks. The front door, timber or not, in all flats, needs to meet that requirement.
