Framed glass-and-aluminium facade
Glass panes held inside aluminium frames made of vertical and horizontal members, fixed within the building’s openings or between its floors. The frame is visible in the overall look and divides the facade into clear modules.
Best for: Buildings with defined openings and a visible frame
Watch out for: The frame fixing and pane sizes are reviewed against the opening and structure
Curtain wall
An outer envelope hung from the building’s structure that does not carry the building, but passes its own weight and the loads on it to the structural frame. It is assembled piece by piece on site or as pre-assembled units, and its design deals with wind, water, movement and thermal separation.
Best for: Facades covering several floors or long stretches
Watch out for: Tied to the building design early and needs full engineering study
Structural glazing
A category in which panes are fixed by bonding them to the frame with a structural silicone sealant, or by point fittings that hold the glass at set points, so the frame is barely visible. These describe two categories, not a particular product, and each needs its own engineering calculation.
Best for: A design seeking a continuous glass look with a light frame
Watch out for: Bonded or point fixing is not settled without qualified design
Glass cladding
Glass panels that cover an existing wall or structure as an outer finish layer, fixed to a secondary framework. The glass type and fixing method depend on the construction of the original wall.
Best for: Renewing the look of an existing building or parts of it
Watch out for: The state of the existing wall decides what is possible
