Thermal Insulation for Extreme Temperatures

The advanced ROHACELL® HERO foam core offers the latest in materials technology for composite structures that are lightweight, less expensive to manufacture, and durable over their lifetime.

The superior insulating performance of  ROHACELL® HERO is an added advantage.

The rigid structural foam not only provides mechanical strength at all of its very low densities, but the innovative closed-cell foam also insulates applications quite effectively from hot or cold environments.

Lightweight “Dual-Use” Sandwich Panels

The ROHACELL® HERO panels are distinctively “dual-use” as it provides both thermal insulation and mechanical strength. Their impressive mechanical strength can fulfill structural demands, while simultaneously suppressing heat transfer.

Potential dual-use sandwich panel applications include shelter systems in harsh environments, satellites, space applications, protective enclosures for components in high altitude aircraft, etc.

Excellent Insulating Performance – At Any Density

Thermal conductivity changes depending on the density of the ROHACELL® HERO product grade.

Thermal performance or insulating capacity increases with the decrease in product density. However, excellent thermal conductivity takes place at all densities.
