Ensure that the siding, siding.X and perforated siding do not come into direct contact with heavy metals (e.g. copper or iron) as this will increase the risk of corrosion. If you wish to use different materials in combination, these must be coated or separated from the aluminium profiles by non-conductive spacers (e.g. plastic washers). Materials must always be separated correctly when being used outdoors.
Siding, siding.X and perforated siding are to be protected from the damaging effects of other building parts (e.g. concrete) or the environment (corrosive elements in the surrounding area such as de-icing salt).
