(57) To avoid the need for nailing through tiles and other cladding elements (10), they
are formed with oppositely directed hook formations (30,32) at opposite edges. These
engage support means, which may be retaining profiles (40) mounted on battens (50).
For example, an upwardly facing hook formation (30) is engageable under a downwardly
directed supporting tongue (46) when the element is tilted. It can then be pivoted
about that tongue (76), into its cladding configuration. Its other hook formation
(32) snap-engages behind the tongue (46) of the adjacent support means, which already
engages the upwardly facing hook portion (30) of another cladding element. Each support
profile (40) extends for most of the width of one or more elements (10) and provides
support (48).
