The basic element of the MK2 construction system is the simple MK2 Panel of expanded polystyrene enclosed between two steel meshes linked together by 80 electro-welded connectors per square metre of surface.
The thickness of the expanded polystyrene core can vary from 3 cm to 20 cm, depending on the needs of the architectural project. The minimum density normally used is Class III (5 kg / m3) and Type F (hardly flammable or self-extinguishing).
The meshes are made of high-strength galvanised steel, with an ultimate tension of 700 MPa and are made up of bars with a diameter of 2.50 mm with an average separation of 7.28 by 6.50 cm in the secondary direction, these constituting a basic reinforcement which is completed with 5 mm diameter longitudinal corrugated bars, in the case of structural panels.
The meshes protrude 50 mm on opposite faces, in such a way that when overlapping each other, they ensure continuity by juxtaposition of the reinforcements, without the need to place additional joining elements. For the joins between panels, on the sides where there is no such overlap, continuity is resolved by means of the flat and angular meshes supplied for this purpose, always ensuring the continuity of the reinforcement and EPS in all joints, meeting the requirements of the applicable regulations.
