BUILDING AN IGLOO
An igloo is basically a dome of ice cubes and snow. Inuits use snow to make their homes because the air pockets in the snow act like isolation. The snow used for the igloos has to have structural strength to be able to be cut without breaking and then be easily stacked. The ice cubes are cut by a hand made knife. The Inuits often take one block of snow out of the igloos structure to form a window. Some Inuits even make a hole through the ice inside of the dome to be able to ice fish inside their homes. An Inuit men can build an igloo in about one hour.
LIVING IN AN IGLOO
To prevent cold air from coming inside the igloo, a tunnel is dug in the snow and a door is put at the end of the tunnel to not let the cold air penetrate the igloo. The entrance (tunnel) acts like a trap to cold air so it doesn’t go inside the Inuit’s dwelling. Out side an igloo temperatures varie at about -45c. and inside of an igloo the temperature varie between about -7c. to about 16c. when the only source of heat is body heat. When the Inuits build their igloos the sleeping areas are always higher then the other areas. That is because heat goes upwards and coldness stays towards the ground. When there is a source of heat inside the igloo the walls tend to melt and then refreeze to make a layer of ice on the walls and then reinforce the structure of the igloo. That said not all Inuits live and build igloos only the Inuits of Canada central Arctic and Greenland live and build igloos.
DIFFERENT TYPES OF IGLOOS
There are mainly three different types of igloos that Inuits build. The smallest of the three is used for hunting trips of only one or two nights. These igloos are often built on open sea ice.
The other igloo considered “medium” is semi-permanent for a medium sized family. It is usually a one roomed igloo for only one or two families, sometimes many of these are made in one area to form an Inuit village.
The largest of the three igloos is 50% for living and the other 50% is used for special occasions. These igloos can have up to 5 rooms and have up to 20 people living inside of it. A large igloo might consist of plenty of small igloos connected together. These large igloos were used to hold committee fest and dances and other occasions.
