Product Description

The CW400 series is a high performance American pressure glazed stick curtainwall system. It has been a leading system (four-sided, mechanically entrapped) in the USA. It lends itself to automated production and is extremely fast to erect on site (2 floors at a time) from inside the building. Each stage of erection and glazing can be easily inspected to prevent any leaks occurring in the finished curtainwall and the building can be closed in and made water-proof in a mill finished state.

Section Sizes

  • 64mm Mullions
  • 64mm / 102mm Transoms

Coloured external trims are applied when the building is nearing completion to maintain an undamaged and pristine finish, obviating the need for further protection. This feature allows thermal separation, is cost effective, and provides the option of different colours choices for inside and outside.

The system incorporates neoprene gaskets fully moulded at the corners and with internal tubular gaskets to give a controlled pressure to the glass over the total perimeter. All glazing is carried out from the inside (depending on design application).

Performance / Testing

Thermosash owns and operates the largest façade testing facility in New Zealand where we test our systems and custom designed suites to ensure compliance with the below codes or project specific requirements:

  • AS/NZS1170 (Structural Design Actions)
  • NZS4211 (Performance of Windows)
  • NZS4223 (Glazing in Buildings)
  • NZS/AS4284:2008 (Water / Air Pressure/ Air Leakage - Meets and exceeds minimum requirements)

All the Thermosash suites are independently laboratory tested to IANZ (International Accreditation New Zealand). Test certificates are available on request.

Maximum Spanning Ability

Thermosash specifically engineers the best suite option for your project taking into consideration span, structural system, and environmental loads (e.g. wind). The spanning ability will vary depending on the above.

Thermosash Suites are recognized as having the largest spanning systems on the market due to our specific engineering capability and the customised nature of the work we complete.

Warranty

The standard warranty is 10 years from the date of practical completion for these products. This covers workmanship and weather tightness, providing the subcontract includes fabrication, installation and glazing of all components, and the maintenance schedule is adhered to.

Maintenance

Maintaining glass, metals and stone are all particular to the environment that they are placed in: eg. marine, environmental pollution, exposure to natural washing, etc.

It is recommended by almost all material suppliers that building washing should occur every 3-6 months to prevent staining to glass and prevent environmental pollutants from corroding metals and to maintain the material warranties.

A full maintenance manual is provided on completion of a project for all the elements integrated within a project. Compliance to a maintenance schedule is essential to maintaining the quality of the installed product over time. Using Thermosash-approved facade maintenance contractor/personnel ensures the highest standards are met.

Key Features

  • An extremely versatile system to accommodate complex architectural geometry.
  • A complete drainage system is incorporated to drain water at every lite.
  • A very wide range of glass and panel thicknesses can be accommodated in the design and opening vents can be incorporated, should this be necessary. The system, which is designed to span two floors, sets out to use the minimum amount of aluminium to meet the design requirements of the specification or specific aesthetic demands.
  • All internal aluminium covers, cills and head trims are isolated from exterior aluminium against the transfer of heat or cold by the use of PVC isolators, giving a complete thermal break. The work is erected and glazed using mill finish aluminium.

Specification

We recommend using Masterspec 4211TS Thermosash Curtain Walling when specifying this suite.

Finishes

  • Polyester powder coat - both standard and special colours available.
  • Anodised - all anodised colours available - commercial grade 20 micron finish recommended.
  • PVF2 Fluorocarbon finishes - available on request.
