Stone Cladding: Example of stone engraving on 40mm red sandstone rainscreen cladding at The Brodick Ferry Terminal on the Isle Of Arran. The image below has the logo of Caledonian MacBrayne, usually shortened to CalMac.

The supporting horizontal profiles for the stone cladding panels are Aluminium which is Class 1 rated non-combustible (see attached document fire properties of aluminium), so this does not add to the fire load.

GRC/GFRC Rainscreen Cladding: The Manser Practice, was commissioned by Merlin Entertainments Ltd to design and deliver the ultimate LEGO family hotel as an enchanted life-size LEGO themed castle for guests to stay in. A fully bespoke Glass Reinforced Concrete (GRC) cladding system supplied by AlterEgo Facades was developed by The Manser Practice for the façade and gives the impression that the hotel has been constructed of 25x scale LEGO bricks. This GRC system was created from tessellating panels formed off site in a predesigned mould which are worked to strict LEGO brick proportions and replicates a unique stonework texture.
