Steel Buildings in Europe

Part 8: Building Envelope 8 - 1 1 INTRODUCTION Metal cladding systems provide an efficient, attractive and reliable solution to the building envelope needs of single storey buildings (steel, concrete or wood framed structures). Over the years, these systems have evolved from the single skin metal cladding often associated with agricultural buildings to highly developed systems used in industrial, retail and leisure applications. However, as with all construction components, the ability of the cladding to satisfy its functional requirements is dependent on its correct specification and installation and, equally as important, on its interaction with the other elements of the building envelope and structure. This publication provides guidance relating to the secondary structures and building envelope types used in single storey buildings. Description is given of the common types of profiled metal cladding systems currently used in Europe. These systems include insulated panels, built-up systems, deck and membrane, and liner trays. Guidance is also given on key issues that should be considered when specifying either the building envelope or its supporting structure. Reference is made to a selection of technical documents published by The Metal Cladding and Roofing Manufacturers Association (MCRMA). These technical documents provide comprehensive guidance on various associated topics, which are applicable throughout Europe and can be readily downloaded from www.mcrma.co.uk. Additional information can also be found on the French language website Acier Construction at http://www.acierconstruction.com Guidance has been included in this document which considers the restraining action of the secondary steelwork to primary steelwork and the restraint provided by cladding sheeting to secondary steelwork. However, in certain countries within Europe (e.g. in France), this restraining behaviour cannot be utilised, and a footnote has been added highlighting where this is the case. 1.1 The building envelope The principal components of a modern metal-clad industrial type building are shown in Figure 1.1.
