Part of a winning team at Wembley’s new Alto development, Sapphire has once again won praise for its innovative balcony design and unrivalled ‘end to end’ support.

Over 370 balconies were safely installed to luxury apartments at an impressive rate of up to 30 a day using Sapphire’s offsite manufactured Cassette® balcony concept.

Sapphire’s Glide-On™ connectors enabled a Rigid connection back to the building that far outperforms the British Standards L/180 structural deflection limits. Some of the balconies had a 1725mm projection. Applying BS EN Standards, this balcony would be allowed to deflect by 9.6mm at the extent. Sapphire Rigidity tests across a few of these size balconies recorded an average of 1.25mm deflection – a massive improvement in the Rigidity and comfortably achieving Sapphire’s Gold standard.

Sapphire’s ‘supply and support’ package for Alto was synchronised with the overall design and build programme and considerations such as crane availability on site. This involved working closely with all parties from concept to completion, including site engineers at the pre-pour stage of early floors to ensure the correct setting out of balcony edge shutters. Specialist equipment, purpose-designed by Sapphire, was also provided to assist a safe and smooth installation, which was carried out by one of Sapphire’s trained installation experts.
