European foreword
This document (prEN 14509-5:2021) has been prepared by Technical Committee CEN/TC 128 “Roof
covering products for discontinuous laying and products for wall cladding”, the secretariat of which is
held by NBN.
This document is currently submitted to the CEN Enquiry.
Introduction
This document covers Annex E in EN 14509:2013 and will be replaced for steel faced sandwich panels
by EN 1993-7 when this Eurocode for design of steel faced sandwich panels will be published. For
sandwich panels with other metal faces, this document will be used.
1 Scope
This document specifies design methods for combination of actions and spans for factory made double
skin metal faced insulating sandwich panels (hereafter sandwich panels). The sandwich panels are for
use in elements for both 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.
NOTE The description of self-supporting sandwich panels is given in prEN 14509-1:2021, Clause 1 and for
structural sandwich panels in prEN 14509-2:2020, Clause 1.

For the purposes of this document, the following terms and definitions apply.
3.1.1
bending moment capacity
maximum bending moment recorded during a test on an individual panel

As impacted by EN 1993-1-3:2006/AC:2009.
As impacted by EN 1999-1-4:2007/AC:2009 and EN 1999-1-4.
3.1.2
bending resistance
characteristic value of bending moment capacity determined on the basis of a test series
3.1.3
bond
adhesion between the face(s) and the core normally provided by an adhesive
3.1.4
ceiling
covering over an internal area
3.1.5
core
layer of material, having thermal insulating properties, which is bonded between two metal faces
Note 1 to entry: Panels with special edge details in the longitudinal joints may utilize different core materials from
the main insulating core (e.g. for improved fire performance) if these edge details do not influence on mechanical
performance of the panel.
3.1.6
edge, longitudinal edge
side of the panel where adjacent panels join together in the same plane
3.1.7
face, facing
flat, lightly profiled or profiled thin metal sheet firmly bonded to the core
3.1.8
flat facing
facing without any rolled or pressed profile, or raised strengthening rib
3.1.9
joint
interface between two panels where the meeting edges have been designed to allow the panels to join
together in the same plane
Note 1 to entry: The joint may incorporate interlocking parts that enhance the mechanical properties of the
system as well as improving the thermal, acoustic and fire performance and restricting air movement.
Note 2 to entry: The term 'joint' does not refer to a junction between cut panels or a junction where the panels
are not installed in the same plane.
