GENERAL SYSTEM OVERVIEW
A simple 50mm strip window system, incorporating a Fixed Glazed or Sash Glazed Chair option in a perimeter Seismic Fame
The system arrangement includes standard 50mm Mullions, 100mm deep Internal Boxed Mullions, and 1 piece transoms.
Panels are generally dead loaded into the seismic cill tray, and the seismic jambs and heads are beaded externally to provide lateral restraint.
The combination of these movement joints allows the system to provide an airtight and weathertight envelope to the building whilst accommodating building structural tolerances, thermal expansion and seismic movements and deflections.
SPANS & CAPACITY
Span Capacity varies project by project based on a number of interrelated variables, but a typical panel size in the 50mm Window System is circa 2400mmH x 1200mmW
The System can be used in demanding wind zones up to 3.6kPa ULS and with a Seismic Interfloor Drift ULS 60mm
Generally for spans above 1400mm high the standard Mullion (50203) is realaced with an Internal Box Mullion
FRAME TYPES & FINISHES
The 50101 Seismic Frame is used at the Head and the Jambs, and the 50102 Bead is fitted externally and held in position with a glazing wedge.
There is a System specific cill tray ((50103) which is designed to accommodate the weight of the system.
The seismic frame and the sill tray have a fixing fin to the inside such that frame fixings are not in the wet cavity and also to give a significant surface area for trim cavity packers and internal air seals.
Similarly there are options for the Seismic Cill. A traditional Cill Tray may be suitable where the *********
SASHES
The system has the capacity to accommodate both top hung and casement sashes. A typical sash size is 1400mm high x 800mm wide.
Sashes are designed as a flush unit, meaning the position of the sash and glass is the same as the fixed frame, - both 50mm thick with the glass in the same in / out position.
This means there is a negative detail around the perimeter of the sash, giving the system a linear architectural feel.
Sizes and configurations vary with local wind pressures and site conditions.
INFILLS & GLAZING CAPACITY
The Glazing cavity of the 50mm Window can be adapted with beads to accommodate a variety of glass thicknesses from 6mm single glazed to 32mm Double glazed.
PERFORMANCE
The 50mm Window System has been tested to a wind pressure (ULS) of 3.6kPa and ULS Interfloor Drift of 60mm
The system performance varies depending on
Panel Size
Mullion Centres
FINISHES AND 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
TBC
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
