China mosaic
Broken-tile reflective roof
Born in Gujarat, Rajasthan, western India.
How it works
A roof terrace finished in a mosaic of broken white glazed tiles. The pale, glassy surface throws the sun back instead of soaking it, and waterproofs the slab, so the roof stays far cooler than a bare grey deck.
In a modern home
A reflective 'cool roof' on an apartment terrace, whether broken-tile mosaic or a white solar-reflective coating, to cut the heat coming through the ceiling.
