580A INSULATED PANEL IDENTIFICATION & LABELLING When the roofing and /or the wall cladding to this building is completed, a label identifying the composition of the insulated panels is to be fitted. This label illustrates the type of Insulated panels fitted, to assist Insurers, Fire Officers, Owners and Occupiers identify the envelope composition. It is a recommendation of the Total BENCHMARK Guarantee that the insulated panel identification label, which has a specific project registration number, is installed in an agreed location. The project architect, cladding subcontractor or owner should place / affix or communicate the positioning / placing of these labels in an appropriate and accessible location on the building.
