GENERAL SYSTEM OVERVIEW
This Structurally Glazed Unitised Curtainwall Suite is designed around a 147mm x 80mm mullion, with interlocking male/female mullions and gutter stack transoms for secure assembly. Panels are top-fixed via brackets, creating a deadload condition with the stack joint sitting at or above slab level. Upper panels engage the joint to transfer wind and lateral loads into the gutter.
The system forms a weather-tight, airtight envelope while accommodating structural movement, thermal expansion, and seismic deflection. A 160mm version is also available, allowing deadloading onto a sill tray with seismic head and jamb details akin to shopfront systems.
SPANS AND CAPACITY
Span Capacity varies project by project based on a number of interrelated variables, but a typical panel size in the 160mm Unitised System is circa 3000 x 1200mmW.
The System can be used in demanding wind zones up to x.xkPa ULS and with a Seismic Interfloor Drift ULS xmm
FRAME TYPES & FEATURES
Whilst a Curtain Wall does not have a “frame” as such, the typical Seismic Head and Jambs are the 160103 Frame with a 160104 Bead which gives a typical deflection channel and bead condition.
At the Seismic Cill, the stack join transom (160213) can be used as a cill accommodating lateral load only from a panel hung from structure above. with the option of the panel being dead loaded into the cill – using the 160105 Standard Cill Tray
INSERTS, SASHES, FINNS & FINISHES
The system has the capacity to accommodate a variety of infill products, including; Top Hung Sashes (in a sash adapter frame) 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 160 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.
The Mullions and Transoms can be left with a Stuctural Sealant finish (where the sealant and Infill Product are on the same external line, or Expressed Beads can be fitted to better express the panel perimeters.
PERFORMANCE
The 160 UCW Base System has been tested to a wind pressure (ULS) of xxxkPa and ULS Interfloor Drift of xxxmm. The curtain wall performance varies depending on:
Panel Size
Mullion Centres
Structural Connection (Positions and Types)
Infill Types (ie Doors, Sashes Sliding Panels)
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.
MAINTENACE
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
