scope:

This European Standard specifies requirements for factory made, structural, double skin metal faced insulating sandwich panels, which are intended for discontinuous laying in the following applications: a) roofs and roof cladding (e.g. for refurbishment); b) external walls and wall cladding (e.g. on brick walls for refurbishment or sandwich panels on liner trays); c) walls (including partitions) and ceilings within the building envelope. It is essential that structural double skin metal faced insulating sandwich panels according to this European Standard (EN 14509-2) fulfil the requirements of EN 14509. This European Standard (EN 14509-2) gives the basic rule for use of structural sandwich panels for structural applications including fixing of panels. The clarification of which application is structural needs to be given by national provisions. The stabilization parameters needed to contribute to stabilization of individual structural elements (supporting structure) as defined as structural class II according to EN 1993-1-3 are included. The insulating core materials covered by this European Standard are rigid polyurethane, expanded polystyrene, extruded polystyrene foam, phenolic foam, cellular glass and mineral wool. Due to durability performance reason coated face material of steel is used only (both organic and metallic coating). Uncoated steel is not used as face material. Panels with edge details that utilise different materials from the main insulating core are included in this European Standard if there is no influence on mechanical performance of the panel. Panels used in cold store applications are included in this European Standard. Panels, put on the market as a component of a cold storage room, building and/or building envelope kit are covered by ETA-Guideline 021 "Cold storage premises kits". When manufactured in accordance with this European Standard and if satisfying the type testing and FPC criteria the panels can be considered as impermeable to water. The water permeability of the assembly is a function of its installation and is only relevant to the joints and fixings. This European Standard does not cover the following: d) sandwich panels with a declared thermal conductivity for the insulating core greater than defined in the relevant harmonized European Standards for insulation materials; e) products consisting of two or more clearly defined layers of different insulating core materials (multi-layered); f) curved panels; g) perforated panels; h) hidden fixings under permanent tension load, e.g. for ceilings; i) special type of fasteners such as 'T' support for ceiling, threaded rods with clamps for wall, omega and clamps for wall and ceiling, injected joint with flashing and threaded rods for wall and ceiling.
