The balcony Cassette® is the core structural unit of a balcony—the part you physically walk onto. It includes:
The deck surface: the visible top layer that residents step onto.
The structural frame: supports the deck and transfers loads back to the building.
The soffit or underside: the underside of the balcony, designed for drainage, aesthetics and compliance.

The balcony Cassette® is a patented unique concept, specially developed by Sapphire incorporating the balustrade, frame, deck and soffits into one fully offsite assembled MMC product. This innovative approach makes construction faster, more efficient, and cost-effective for residential developments – simplifying the balcony journey.

Sapphire’s Cassette® simplifies balcony construction by combining the frame, deck, and soffits into one offsite-assembled unit. Made from non-combustible Class A aluminium, it enhances fire safety while ensuring consistent quality. Its integrated drainage design channels rainwater through the deck and into soffits that disperse it quickly and evenly. The result is a lighter, safer, and more efficient balcony solution.
