The entire unit is thermal bridge free, despite the fact that a steel frame has been used. All thermal bridges throughout the interior of the vehicle are insulated using X-trem isolation and finished with polyester trimming. X-trem isolation is one of the highest quality insulation materials available, ensuring condensation is eliminated.

The sandwich panel walls of the unit are 60mm thick and are reinforced with high-density foam where necessary. On request, the Bliss Mobil unit can be fitted with bullet-proof walls.
