Fire performant sandwich panels for cladding

ArcelorMittal offers a wide range of polyisocyanurate (PIR) insulated wall panels. The Promisol® architectural panels with hidden and visible fixing systems and different surface finishes offer freedom of design with respect to the most demanding thermal regulations. The panel has a double joint system combined with a special air leakage seal in order to comply with the requirements of air tightness.

Promisol® S and Promisol® V are now also available in the iQ⁺ System® range with an insulation core of iQ⁺ polyisocyanurate (PIR) foam designed to improve the energy efficiency of buildings and their environmental footprint.
