Dome igloo, also known as igloo or igloo, is a kind of shelter built with snow, which is usually built in time when snow is easy to press.
Although the igloo is stereotypically associated with all Inuit and Eskimo people, it has traditionally been associated with people in Canada's central Arctic and Greenland's Thule region. Other Inuit tend to use snow to separate their houses, which are made of whale bones and leather. Snow is used because the air pockets trapped in it make it an insulator. On the outside, the temperature may be as low as - 45 ° C (- 49 ° f), but on the inside, when heated by human heat alone, the temperature range may be between - 7 and 16 ° C (19 to 61 ° f).
The snow for the construction of the igloo must have sufficient structural strength for proper cutting and stacking. The best snow to use for this purpose is wind blown snow, which compacts and interlocks ice crystals. Holes cut from snow are often used as the lower half of a shelter. Sometimes, a short tunnel is built at the entrance to reduce wind and heat loss when the door is opened. The effective insulation of snow keeps the interior of the igloo relatively warm. In some cases, a transparent piece of ice is inserted to allow light to enter the igloo. Animal skin is used as a flap to keep warm air. Igloos' bed, used as a winter sanctuary, is made of ice and reindeer skin. These "ice beds" are unique to the region and the Inuit culture.
The dome igloo is structurally unique because it is a dome that can be lifted and polished from individual bricks against each other so that no additional support structure is required during construction. A properly constructed igloo will support the weight of people standing on the roof. In the traditional Inuit igloo, heat from the kudlik causes the interior to melt slightly. This melting and refreezing creates a layer of ice that helps the strength of the igloo.
