Fire Performance

Proteus rainscreen systems are fully tested to the required construction product standards for fire performance.

WarringtonFire who are part of the Element group have classified the full range of our honeycomb panel systems (Proteus HR, Proteus GL, and Proteus CX) and our insulated spandrel panels (Proteus SP) in accordance with the Euroclass system for the reaction to fire of construction products. The EN 13501 classification is achieved based upon single burning item tests (EN 13823) for each panel specification along with calorific data (EN 1716 or EN 1182) for each individual material layer that makes up the panel.

This classification confirms that the panels are of very limited combustibility and can therefore be used in facades of all heights without further testing, provided that all the other materials within the wall are also A2 classified or better.

Listed below are the full classification for the different specifications of each product, including sub-classifications for smoke production and flaming droplets.
