Partitions

A partition apparatus for attachment to a supporting structure (1) to partition a space comprises a first panel part (3A) and a second panel part (3B) separate each providing a separate portion of the partition. An interface part (4) attaches to the supporting structure to form an interface joining at least one of the first and second panel parts to the supporting structure. The first and second panel parts each comprise a respective groove (9) along a respective peripheral edge thereof. A batten part (30) inserts into the groove of the first panel part such that a part of the batten protrudes from the peripheral edge of the first panel part. This defines a protruding tongue for insertion along the groove of the second panel part to form a tongue-in-groove joint joining the first panel part to the second panel part to partition said space.
