Shadetread™ Downloads

Thermosash Shadetread™ - is an engineered open grate aluminium flooring system, originally designed as a maintenance and light weight trafficable access floor. Other practical uses include platforms to the exterior façade allowing a safe access system for cleaning - doubling as an effective shading device. This product has been predominantly specified into our Thermosash twin-wall curtainwall systems, allowing safe light weight access through the cavity zone, whilst allowing maximum convective air flow in these passive ventilated building designs.

When specifying the screens the following factors need to be considered. Our in-house engineers then undertake analysis to provide the most structurally economic solution:

  • Screen use - vertical or horizontal shade device / human traffic / ventilation
  • Shade requirement
  • Wind loading
  • Seismic loading back to the structure
  • Fixing locations


  • Panel size is limited only by Anodise bath / Powdercoating or transporting limitations - call us to discuss your project
  • Can be powder coated or anodised to any available colour.
