Roof tile system with integrated rainwater channels leading to guttering system inside roof

摘要

The roof tiles have rainwater gutters (1, 2) between raised humps (3, 5). The tiles have rectangular apertures (7) in the gutters. Set into the gutters are channel assemblies (8). Rainwater flows through grilles in the channel assemblies into internal pipes. The water collected inside the building can be used for flushing toilets or other grey water uses.
