DIN EN 12428:2013-04

This European Standard specifies a method for calculating the thermal transmittance of industrial, commercial and garage doors in a closed position. The doors are intended for installation in areas in the reach of people, for which the main intended uses are giving safe access for goods, vehicles and persons in industrial, commercial or residential premises. The doors may be manually or power operated. This document applies to all doors provided in accordance with EN 13241-1. The calculation can include different types of glazing, frames with or without thermal breaks, and different types of opaque panels and thermal bridge effects at the edge of the panel or joint between the glazed area, the frame area and the panel area is taken into account. The follwing factors are not taken into account: the effects of solar radiation, heat transfer caused by air leakage, calculation of condensation, additional heat transfer at the corners and edges of the door connections to the main building structure, and thermal effects between the door and the main building structure. The committee responsible for this standard is NA 005-09-01 AA "Türen, Tore, Fenster, Abschlüsse, Baubeschläge und Vorhangfassaden (SpA zu CEN/TC 33 und ISO/TC 162)" ("Doors, windows, shutters, building hardware and curtain walling (Mirror Committee of CEN/TC 33 and ISO/TC 162)") at DIN.
