Cellular plastics — Self-supporting metal faced sandwich panels — Design methods

Scope

This document specifies design methods for combination of actions and spans for factory made, self-supporting, double skin metal faced insulating sandwich panels (hereafter sandwich panels) according to ISO/DIS 17880:2025.
The sandwich panels are for use in self-supporting and structural applications in roofs, in external and internal walls (including partitions) and in ceilings in buildings as well as those in cold store applications.
This document covers uniformly distributed loads and thermal gradients, it gives no information about normal forced axially loaded sandwich panels, torsional loaded sandwich panels or sandwich panels as a part of a diaphragm.
