What is the definition of metal cladding?
Constructions involving metal cladding are roof or wall systems where metal forms an integral part of the construction, such as metal twin skin systems where the insulation is located between the metal skins and where the metal skins are typically in the range 0.4 mm to 1.2 mm. Cladding with z-spacers would come into this category as would composite metal panel systems. If the metal is simply used as an external shield against weather, such as a rainscreen, this is not classed, for the purposes of SBEM calculations as “metal cladding”.
