The System CW optimizes insulation coverage and composite action, providing designers the highest level of insulation value in a composite panel.
Thermomass System CW is a patented insulation system designed to create a structurally-composite concrete sandwich wall in both plant precast and site-cast tilt-up applications. The system is unique in that it forces the two wythes or layers of concrete to act together structurally, creating a thinner panel.
Thermomass didn’t invent the composite sandwich wall panel, but we made it a lot more thermally efficient. Whereas traditional composite sandwich wall panels utilized metal connectors or solid sections of concrete to develop composite action, System CW optimizes insulation coverage and composite action, providing designers the highest level of insulation value in a composite panel.
The two main components of the system are CC series fiber-composite connectors and either extruded polystyrene or polyisocyanurate insulation. Thermomass supplies both components of the system – the connectors and the fabricated insulation as a complete system. The CC series connectors are installed through pre-determined slots in the rigid insulation, providing a grid of connectors across the body of the panel. The CC series fiber composite connectors are tested in accordance with ICC Acceptance Criteria 320, verifying their compliance with the building code.
The grid of connectors behaves like a verendeel truss to resist the loads imposed upon the panel without sacrificing insulation coverage. This is key in creating a thermally efficient and structurally sound composite wall panel.

This easy to use software allows the designer to integrate the appropriate number of connectors necessary to develop the composite action needed for the panel.
