PW100 4 sided flush glazed

Introduction 
The Thermosash PW100 is a four sided structurally glazed curtainwall suite 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 advantages of this system is whilst it utlises 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 and yet it is more economic to use than the similiar in appearance to the high performance PW1000.

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.

Design limitations of the Unitised Low Rise suite are;

  • Lower floor to floor heights than PW1000
  • Best used where the site has low wind loads
  • Most appropriate to smaller module sizes
  • Where building movement is low

It is reccomended to discuss your project with us early to determine the best suited suite for your needs.

Product Features

  • Designed to accommodate building movements - both vertical and horizontal (seismic)
  • Allows for 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 it's integration with the glazing system to ensure glass warranties are complied with

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 accomodate opening sashes suitable for high rise installations. 

Section Sizes
75/100mm Mullions 
75/100mm Transomes

Specification 
We recommend using Masterspec 4211TS Curtainwall when specifying this suite.

Surface Finishing 

  • Polyester powdercoat  - Both standard and special colours available

  • Anodised - All anodised colours available - commercial grade 20 Micronfinish recommended
  • PVF2 Flourocarbon finishes - Available on request

 Performance / Testing

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

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.

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

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 - Looking After Your Building 
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.
