Abstract: There is provided a roof cladding consisting of elements (10) of recycled plastics, material comprising a body portion (11), a batten engagement portion (12) located at the leading edge (14) of the body portion (11) and a batten back stop (13) being a transverse rib located on the underside of the body portion (11) at a spacing from the batten engagement means (12) determined by the pitch or spacing of the roofing battens (15). The batten engagement portion (12) comprises a downward depending web (16) adapted to bear on the up-slope face of the roofing batten (15), and a lower web (17) extending therefrom to lay adjacent the under surface of the batten (15) in use. The edge of the lower web (17) toward the leading edge (14) is provided with a locking lug (20) in the form of a ridge adapted to pass the batten (15) against the resilient bias of the downward depending web (16) and the lower web (17), to engage the leading face of the roof batten (15).

Abstract: There is provided cladding apparatus comprising a body portion (108) having an inner surface (110) and an outer surface (112) extending longitudinally between a leading edge (114) and a trailing edge (116) and transversely between opposed side edges (118). The leading edge (114) is provided with a formation (124) which inter-engages with complementary formation (126) provided on an adjacent body portion thereby permitting the body portions to inter-engage when laid in a longitudinal sequence. The body portion (108) is provided with a pair of longitudinally extending elongate mounting portions (128) on the inner surface (110) thereof. A longitudinal mounting batten (144) is attached to the fascia panel (106) adjacent to the exposed edge of the tiles (104), and into which the elongate mounting portions (128) may slide.

Abstract: There is provided solar energy harvesting apparatus (20) including a clear polycarbonate body (21) including a transparent front face (23) and supporting a thermal absorber (27) adapted to absorb incident solar radiation. The thermal absorber (27) transfers heat via a fluid connector (28) to a circulated-fluid system and in addition controls the temperature of a photovoltaic element (24) mounted on the absorber (27) and connected to an electrical harness by electrical connectors (25, 26). The polycarbonate body (21) has complementary edge mating profiles (32, 33) engaging with a standard-tiled roof structure to replace some of the standard tiles thereof, and is secured conventionally to roof battens by a batten screw (29).
