CW600 High Performance Stickwall - Butt Glazed Vertically - Mechanically Engaged Horizontally


Our CW600 system is a high performance American stick wall product which provides flush glazed vertical aesthetics and mechanically entrapped horizontals. This curtainwall system has been approved by Dow Corning for the application of their one-part structural silicone products. The CW600 system (and the subsequently developed CW900 system) has been designed to accommodate granite and composite aluminium panels. 

The concept is best expressed in photographs and those shown will illustrate only a few of the building claddings erected by Thermosash. It is usual in both these designs for the internal head and cill linings to be part of the curtainwall. All internal aluminium has a thermal discontinuity from the external aluminium.  

Product Features

  • Integrates with the CW400 suite. 
  • Designed to provide an alternative to the "glass box" effect of curtainwalls. 
  • Enables the cladding of the building to keep pace with fast primary structure erection. 
  • Designed to reduce significantly the aluminium showing on the outside of the building. 
  • Provide a product which could include alternative cladding materials to glass.

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.


The standard warranty is 5 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.
