MASTER-C panels are continuous production line prefabricated panels, and are composed of two faces of prepainted galvanized steel, bonded to a core of rigid polyurethane (PUR) or polyisocyanurate (PIR) foam, forming a sandwich type element with tongue and groove joints.

MASTER-C panels are specially designed for use in all types of roofs, both for industrial construction and for modular or commercial buildings.

Installation is very simple, and provides total watertightness (roof slopes of over 4%).

MASTER-C panels have a tongue and groove jointing system with a steel cover cap that hides and protects the fasteners and ensures the watertightness of the system. Regarding the external profile of the panel, there are two different designs, with a choice of two-rib panels and three-rib panels, both available in seven different thicknesses, with two different interior rib designs and a wide range of colours. Additionally, MASTERPANEL also offers the option of panels manufactured with PIR (polyisocyanurate) self-extinguishing foam with a B-s1, d0 certification under Euroclasses (UNE-EN 13501).
