Glass Fins & Louvres


Thermosash has the unique ability to design and integrate complex glass elements into our façades beyond that perceived capable by many. This is possible from our many years in the industry, our capable engineers and installation crews. 

Our curtain and panelwalls are capable of cantilevering glass fins and screens up to 1000mm from the face of our curtainwall, with no additional structure require by other trades.

The glass can be purely aesthetic or, with ceramic fritting and with input from our glass engineers, become a performance based solar shading or privacy glass element.

Product Features

  • Custom designed / engineered element.

  • Often incorporated with a Thermosash façade system - also can be retrofitted to an existing building.

We recommend using Masterspec 4211TS Curtainwalling or Masterspec 4251TS Commercial Windows in conjunction with specialty glazing when specifying this system.
