Curtain Wall

Curtain Wall Systems can be used where the design of a building requires the glazing span two or more floors of a façade to create the impression of a continuous wall of glass. This can be done both vertically and horizontally on the outside of the structure thereby maximizing the internal floor area.

With the use of high-performing, sound-reducing, tinted or reflective glass and concealed structurally glazed mullions, the appearance of the façade can be created to express horizontal or vertical lines. In many cases, the Curtain Wall System can be used to overclad existing buildings, giving them a totally new lease on life with a modern appearance.

Curtain Wall Systems offer a choice of stickform and unitised methods of manufacture and installation. Each system is unique and offers the building designer flexibility in design and appearance in keeping with current environment issues such as thermal efficiency, ventilation and natural light.

Unitised Systems

Flush Glaze
The Flush Glaze Systems are a versatile product that can be used in a variety of situations from the single-storey office/factory complex to multi-storey, high-rise apartments/office towers.
Originally designed in 1986 under the Oakley Commercial brand, with 100mm and 150mm range, the system has been used extensively in all parts of New Zealand and overseas and updated regularly since.

Greater Depths
Already New Zealand’s leading solution for glass curtain walls, the highly versatile Flush Glaze range is now available in greater depths, giving superior strength and meaning increased spans can be accommodated before a larger base size is required.

New depths available:

  • 106mm
  • 136mm
  • 159mm

The system now integrates more seamlessly with our other product systems, including the Atlantic48™ and Shop Front ranges, to ensure a flawless architectural result.

Improved Strength & Performance
With deeper pockets that give increased glass ‘bite’, the new range exceeds New Zealand compliance requirements. Stack Joints capable of up to 20mm of movement and full perimeter seismic frames mean the facade is semi-isolated in the event of an earthquake.

Optimal Efficiency
As well as improving aesthetic, the new depths reduce time and cost to build, providing a highly efficient solution for the client.

Versatile Glazing Options
The updated product suite in some configurations can accommodate single or double-glazing, up to 32mm thick. Both captive and structurally-glazed options are available.
