GRC (Glass-fibre Reinforced Concrete) or similar imitations are a recent trend and with it GRC balcony cladding and other similar composite materials, have become more common as balcony fascias.
Typically this is to give the balconies and façade a more flowing aesthetic feel. Most commonly, Sapphire will create a frame, or brackets fixing to the Cassette® to allow the stone fascia’s, etc. to be fixed easier.
Alternatively, there are realistic stone effect powder coatings and finishes which can be applied to standard aluminium soffits, which are lighter and can often be a cost saving, as well as avoiding further finishing works during or after balcony delivery/install.
GRC balcony cladding would typically be added after delivery of the balconies to site and before balconies have been installed. However, adding the GRC balcony cladding can be done once the balcony has been installed.
