This tent is specified for cold climate.
The concept combines the strengths of different means of refugee accommodation, the warmth of a mass shelter, the privacy of a family tent, and the community building capacity of a clusterization set-up of tents.
The tent consists of five family units set up wall to wall, enclosing a circle in the middle.
The single family units offer privacy while the courtyard in the centre serves as a meeting place, supports community building and therefore social stability within the camp.
By setting family units wall to wall in a circle, heat loss at the sides of the tents is reduced.
The round tent shape is heat efficient.
The enclosed courtyard is covered with a roof and warmed by the tents around.
Each family unit is set up separately, afterwards joined to a ring.
The construction relies on a combination of aluminium poles (diameter 16mm) and blow-up tubes.
The poles are connected first to form the carrying structure.
Then the tubes are pumped up to shape out the form and put an insulating layer of air between the two linings.
As the tubes aren’t the carrying structure and don’t have to be very strong, they can be made of light PU-coated Polyester and pumped up manually.
Both poles and tubes are sewn into the fabric for easy set-up.
The layers of polyester fabric on the outside (waterproof) and Trevira on the inside (fire resistant) are filled with polyester wadding inbetween because in contrast to air it does not only have insulation but also heat storing capacities.
Each family unit of 24 m² serves 6-7 people (UNHCR-standards), the complete ring 30- 35 people. Because of light-weight materials each has a packed size of only 1m³ and a weighs 28 kg. Non-toxic materials make it ecologically sound.
