Product Overview

Glide-on Cassette® balconies are a patented unique concept, specially developed by Sapphire’s to make it simpler, faster and more cost-effective to provide high quality balconies for residential projects.

Offering home builders, developers and contractors the first real alternative to traditional balcony design and construction, this patent-protected system combines the benefits of pre-fabricated balcony ‘Cassettes®’ with fast installation using our own innovative connectors.

Sapphire’s pioneering approach is based on the manufacture of ‘semi-modular’ units (using standard components and methodology whilst manufacturing to exact project dimensions etc).

This enables us to maximise the efficiencies associated with producing standard, repeatable units, whilst still allowing design variations to be made to each module as required.

Once delivered to site, the individual balcony modules simply ‘glide’ on to pre-erected supporting brackets.

Sapphire’s combination of offsite manufactured Cassettes® with these glide-on balcony brackets have already proved to save time and cost on a number of prestigious residential projects, resulting in repeat orders from satisfied clients.


Using Sapphire’s pioneering glide-on balcony bracket system, a record of 22 Offsite manufactured balcony units (the entire project quantity), including glass balustrades and sub-deck, were installed to new West London apartments in just 6 hours.

Fully assembled balcony modules, together with Sapphire’s innovative glide-on connectors, enabled install a balcony in 6.5 minutes.

Fascias, soffits and drainage systems can be pre-installed, reducing time on site even further. As the glide on connection means that you don’t need to access the bolts from underneath like a traditional bolt on balcony.

Sapphire’s lighter, modularised balcony Cassette® concept delivers both architectural flexibility and fast track construction benefits. The light weight of the Cassette® balconies enables the reducing of the number of brackets needed to fix the balcony to the building ‎which in turn can return substantial cost savings.

Whilst designing the cassette balconies, the base fixing ‎has been synergistically engineered in such a way that it works seamlessly with water drainage and also eliminates the need for additional base fixings for frameless structural glass making it more cost effective than framed balustrade systems on these cassette balconies.


We recommend that you use the Cassette® balconies in conjunction with glide on brackets and frameless structural gla‎ss balustrading.
