Excellent natural ventilation

Every Bliss Mobil is fitted with windows and roof hatches which are as large as the construction of the unit allows. The windows and roof hatches ensure excellent, natural ventilation.
The windows can be opened to any position. Stale air can flow upwards easily without being blocked by the windows. Ventilation during heavy rainfall is made possible due to secure locking in the outer position (ventilation position) of the window frame, allowing fresh air to circulate. This feature is also often used by those who have to overnight in an area where it is not particularly safe. 

Successive insulation chambers inside the frame provide maximal heat insulation. The windows are double glazed with a special thermal coating and a gas-filled airspace is in place to minimise heat loss. Integrated aluminium-coated roller blinds keep radiant energy out.

Solar operated inlet fans

In addition to the windows and roof hatches, two solar-operated fans ensure the circulation of fresh air throughout the Bliss Mobil interior. The fans have their own solar powered circuit and do not rely on the battery packs for operation. Using the switch on the fan, the operating mode (inlet or oulet) can be selected or the fans can be switched off if desired.
