Delivering cutting-edge aesthetics and outstanding performance, the Proteus HR rainscreen system is built for modern architectural excellence. 

The Proteus HR system is engineered for strength, durability, and precision. It features an aluminium honeycomb core, enclosed between two thin metal sheets and framed by a perimeter extrusion. This construction allows for straightforward installation using either direct or hook fixing methods, securely attaching to the Proteus vertical carrier system.

The honeycomb structure delivers high strength while keeping the panels lightweight. This enables the use of thinner materials without sacrificing durability. The reduced weight lowers structural load, reduces material use, and improves environmental efficiency.

The System

The naturally optimised structure of Proteus HR’s honeycomb core delivers maximum compression and shear resistance using minimal material.
