  • Average thickness 7mm in water pouring part
  • Thermal resistivity = Panel thickness / 1000 X Thermal conductivity + Polyurethane foam thickness / 1000 x Thermal conductivity + 1 / Convective heat transfer coefficient from exterior panel
  • Exterior panel temperature = ambient temperature - (ambient temperature - Panel interior panel) / Convective heat transfer coefficient from exterior panel × Thermal resistivity
  • Exterior temperature > dew point temperature = No dew condensation
  • Proper ventilation prevents dew condensation *Psychrometric chart
