PW1000

Product Description

Thermosash PW1000 : four sided structurally glazed curtainwall suite designed for highrise or lowrise applications where the project has large spans or large panes of glass requiring higher strength systems.

The suite has been extensively used and proven in New Zealand and our export markets since 1985. The advantage of this system is, whilst it utilises a mullion and transom system internally to hold the glass or other elements, the surface is generally free from any visible aluminum structural element - providing a smooth glass face.

Mullion Sizes: 75mm / 100mm / 150mm / 200mm

We have the ability where necessary, to structurally supplement the sections when the suite is exposed to high floor to floor spans or high wind zones, thus potentially reducing the need for additional primary or secondary structure to be provided by the Main Contractor.

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.

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.

Pressure Equalised design

The weathering design of these curtainwall suites follows recognised international curtainwall 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, ie it is the prime cause of any leakage.

Sizing of modules is generally only limited by the project design requirements, economic considerations, transport and site crane installation limitations. We would be happy to discuss what these might be on your project.

Engineering

We custom design all our suites to suit projects to maximise the efficiencies within the suite and often to incorporate added elements or unique building structures, building movements or floor heights.

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 PW1000 can accommodate opening sashes suitable for highrise 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).

Aluminium is 100% recyclable and all aluminium from refurbished sites and from our manufacturing process is environmentally managed back to our key suppliers and processed back into raw billet form.

Installation

Our systems are prefabricated and glazed in a factory environment, stored if necessary, and transported for just-in-time site delivery. We have highly skilled installation teams who work safely and effectively to close in buildings rapidly.

These prefabricated and glazed panels are delivered to the floors in crates and positioned by floor mounted cranes or monorail units. The panels have interlocking legs, requiring sequential placement around the building floor before the next level can be installed.

It is highly recommended that the units are installed from ground up in predetermined directional order to maintain the best detail connection between panels. Special methodologies need to be considered when recladding a building demands a top-down approach.

Curtainwall is almost always hung from the top of each floor section (dead loaded) and attached at the base of the unit to resist windload. The Thermosash specific engineered brackets attach at each floor either on the top of the slab, to the edge of the slab or under the slab as necessitated by the project design and engineering requirements of the selected system.

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.

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.

Key Features

This engineered façade curtainwall is designed to accommodate:

  • building movements - both vertical and horizontal (seismic).
  • differential rates of thermal expansion and contraction.
  • connection details to accommodate construction tolerances.
  • structural member strengths comply with Code or project specification.
  • glass design and its integration with the glazing system to ensure glass warranties are complied with.
