GENERAL SYSTEM OVERVIEW
This Structurally Glazed Unitised Curtainwall Suite is based on the 180 UCW System, enhanced with polyamide beads for improved thermal performance. Mullions and transoms are nominally 164mm x 80mm, adjustable based on glass and bead dimensions. The system features male/female interlocking mullions and gutter stack transoms.
Panels are typically deadloaded via brackets at the top, placing the stack joint at or above slab level. The panel above slots into this joint, transferring wind and lateral loads into the gutter. Together, these movement joints provide an airtight, weather-tight envelope while accommodating structural tolerances, thermal expansion, and seismic movement.
Spans and Capacity
Span Capacity varies project by project based on a number of interrelated variables, but a typical panel size in the 180 TE Unitised System is circa 3200mmH x 1400mmW
The System can be used in demanding wind zones up to 3.6kPa ULS and with a Seismic Interfloor Drift ULS 60mm
FRAME TYPES & FEATURES
Whilst a Curtain Wall does not have a “frame” as such, there are different Seismic Heads, Jambs and Cills that give different aesthetic outcomes at structural interfaces.
Typical Seismic Head and Jambs may be the 180-011 Frame with a 180-012 Bead which gives a typical deflection channel and bead condition
A Sill Tray (180-004) may be used at the cill with the option of the panel being dead loaded into the cill – or the cill accommodating lateral load only from a panel hung from structure above.
INSERTS, SASHES, FINNS & FINISHES
The system has the capacity to accommodate a variety of infill products, including; Top Hung Sashes and Insert Doors (open in and out).
In additional to this, brackets off mullions (or transoms) can support external feature fins, shading devices, and well as signage, and feature panels external to the curtain wall.
Sizes and configurations vary with local wind pressures and site conditions.
INFILLS & GLAZING CAPACITY
The Glazing cavity of the 180 TE UCW can be adapted with beads to accommodate a variety of glass thicknesses to suit almost any glazing requirement.
In addition, a variety of infill material can be utilised, including and not limited to; Glass, Aluminium Panel, Composite Panels, Solid Stone, GRC, Teracotta Tiles and Bricks
PERFORMANCE
The 180 UCW Base System has been tested to a wind pressure (ULS) of 3.6kPa and ULS Interfloor Drift of 60mm
The curtain wall performance varies depending on
Panel Size
Mullion Centres
Structural Connection (Positions and Types)
Infill Types (ie Doors, Sashes)
FINISHES & COLOURS
The System can be Surface Finished in a variety of options.
Powdercoat to AAMA2604 in Standard Dulux, Akzo Nobel or Custom Colours
PVDF Finish to AAMA2605
Anodised 20 Micron
Electrophoresis Anodised Finish
PERFORMANCE TESTING
KFI Curtain Wall Systems are generally Tested at an ILAC Accredited International Testing Facility to the Requirements of AS/NZS 4284
A library of Tests are kept for each system type, and if a project performance requirement exceeds or differs significantly from test reports on file, a project specific test can be carried out.
INSTALLATION
Installation is typically carried out by KFI as a part of the façade contract in order to give effect to warranties and producer statements.
MAINTENANCE
At the completion of a project KFI will compile and hand over a set of Completion Documents which includes a written Operation and Maintenance Manual – specifying the required cleaning, maintenance and inspection regime for various parts of the façade for the duration of the warranty period.
NZBC COMPLIANCE
A Compliance Pathway Report is created for each project, listing compliance with the following mandatory provisions of the New Zealand Building Code
B1 – Structure
B2 – Durability
E2 – External Moisture
F2 – Hazardous Building Materials
F4 – Safety from Falling
In addition to this KFI provides information on the Curtain Wall System to enable the satisfaction of
C3 – Fire affecting Areas Beyond the Source
G4 – Ventilation
G6 – Airborne and Impact Sound
G7 – Natural Light
H1 – Energy Efficiency
