Royal Hamilius — Six Seven Restaurant: fire-rated glass floor on the roof
Replacing a triangular fire-rated floor panel on a restaurant roof, in the heart of Luxembourg City.

The challenge
The starting point on site
The terrace of the Six Seven restaurant at Royal Hamilius sits on a black steel geodesic frame made up of triangular glass panels. One of them had to be replaced at short notice: a one-off piece with an irregular cut, reachable only at height, carrying a set of technical demands that rarely meet on a single pane.
