Insulated panels or sandwich panels are one of a number of construction products for which a harmonised standard has been prepared. Standards are prepared by CEN.
In the case of sandwich panels a committee of European experts, chaired by EPIC, have developed a standard covering the use of panels for external roofs and walls and internally for walls, ceilings and partitions. The standard – EN 14509 – was formally accepted by the Member States in 2006 and is the basis of CE Marking of all metal faced insulated panels (Sandwich Panels).
An update of the Standard is due for release at the end of 2012. The Sandwich Panel Standard has been adopted by the UK as BS EN 14509.
