PW60

Product Description

Thermosash PW60 : is a two sided structurally glazed curtainwall with mechanically engaged expressed horizontal transom elements, providing an accent on the horizontal aspect of the building facade. Suitable for low or high rise applications where small spans or where smaller panes of glass are envisioned.

The suite has been extensively used and proven in New Zealand and our export markets since 1994. The advantage of this system is that it offers a potentially smooth surface across the elevation of the building between the transoms. The PW60 is similar in appearance to our high performance PW600 suite.

Section Sizes

  • 75 / 100mm Mullions
  • 75 / 100mm Transoms

Maximum spanning ability

The spanning ability will vary depending on the structural system and environmental loads (e.g. wind).  Thermosash specifically engineers the best suite options to meet project requirements.

PW60 is best used for:

  • Lower floor to floor heights - greater heights are achievable with our PW600 suite
  • Sites with low wind loads
  • Smaller module sizes
  • Areas where there is low building movement

We recommend discussing your project with us early so that we can advise on the best suite solutions for your needs - please contact us.

Pressure equalised design

The weathering design of these suites follows recognised international curtain wall design principles - rainscreen pressure equalisation and system drainage - which requires primary and secondary weathering. The rainscreen acts as a primary water-stop, the second airseal and cavity acts as a backup to collect and drain away any water that manages to penetrate the primary rainscreen barrier.

All internal cavities of the system are designed to be pressure equalised (i.e. no pressure differential between the outside face and any internal cavity). This feature allows the water which penetrates the rainscreen to drain freely back to the exterior. The rear air seal is critical to the system's weathering performance as air infiltration acts as the medium which transports water through to the building's interior, i.e. it is the prime cause of any leakage.

Integrated Elements

Almost an unlimited type of materials can be integrated into a unitised panel, including different glass types, metals, brackets to receive externally mounted fins, louvres, venetians or building signage for example. The PW100 can accommodate opening sashes suitable for high rise installations.

Low-Carbon Aluminium

Thermosash partners with a local NZ-owned extruder achieving a lower carbon footprint than the global average - offering reduced upfront carbon emissions. (find out more about our Sustainable Aluminium).

Performance / Testing

Thermosash owns and operates the largest facade 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)
  • 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.

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, e.g. 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 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.
