PW600 2 sided flush glazed vertically

PW600 2 sided flush glazed vertically - mechanically engaged horizontally

The Thermosash PW600 is a two sided structurally glazed curtainwall with mechanically engaged expressed horizontal transom elements, providing an accent on the horizontal aspect of the building façade. The PW Series Suites have been extensively used and proven in New Zealand and our export markets since 1985. 

The advantage of this system, is whilst it utlises a mullion system internally to hold the glass (structurally glazed) or other elements, the transoms are expressed, mechanically encapturing the glass, offering a potentially smooth surface across the building between transom lines generally free from any visible aluminium structural element. 

The weathering design of these 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.
