Glide-On Cassette balconies: over 30 installed in a day

Although a lot more elegant, it’s like a fork lift lifting a pallet, it’s that simple.

The first part is the bracketry which can be chosen from a range of cast-in or post-fixed brackets to enable the connection to the main building structure or floor slab, each with steel arms protruding from the façade. Read more about Glide-On Connections

The balcony Cassette® (the frame structure) is a deck made with oversized holes to receive the steel arms when the Cassette® is craned into position. Each Cassette® is delivered preassembled and factory finished to a high quality standard with minimal on site finishing. Read more about balcony structures

The third part is the balustrade, forming a perimeter guard around the balcony. This can range from frameless structural glass to framed systems (eg vertical infill bars) or solid walls. Read more about balcony balustrading
