Igloos are temporary homes made of blocks of snow. The Eskimos build igloos when they are on long hunting trips. Snow is the easiest material to get hold of.

The igloo is a brilliant shelter solution, ideally suited to a region where more traditional building materials were virtually nonexistent. No trees grow in the land of ice and snow above the arctic circle. Rocks and stones that might otherwise serve as construction material are buried under mountains of snow or lie out of reach beneath the ocean and ice flows.
Contrary to popular myth, the native peoples of the far north didn't live in the same igloo all year around. Survival in the far north depended upon hunting and successful hunting requires that you go where game can be found. The igloo was primarily used as a temporary hunting shelter. One of the beauties of an igloo is that a hunter didn't have to be weighted down with carrying that night's shelter on his back. One could be created in an hour or less with a few simple tools and the one material in plentiful supply. Snow.

Eskimo Ice Houses

Not much wood around for them to use. Ice will only ever be as cold as 0 degrees C. [Well, okay maybe a bit colder, but not much unless it has been "super" cooled in a lab.] Even if outside the igloo is 50 below 0, inside it will hover around 0 degrees C. And, the dome shape, usually with some sort of vent built into the top, allows for het and smoke from any fire to move up and out. It may cause a glazing (or icing over) effect on the inside walls, but that only adds to the structural stability of the ice house. The inner most layer of the wall may melt a bit, but the rest of the wall will refreeze it into ice instead of just packed snow.

I would think they use ice or compacted snow because it is the most common building material around. The tundra is not a place that really grows trees or other plants that could be used for this purpose. Also, I would think a carbon based structure wouldn't insulate as well as think snow and ice. Igloos can get quite toasty inside.

Answer from an Eskimo from Alaska. Snow is used and it has to be the right consistency. It can't be from freshly fallen snow. Using Ice would be dangerous.

They don't. They build it out of snow. Since there is a lot of snow and very little else in the Artic it is the logical building material.

Because there are no other materials to build a shelter out of in arctic.
There are no trees, the ground is frozen solid year round.
