How do you ventilate an igloo?

For proper ventilation, never seal or close the entrance. Walls: Cut the blocks into a spiral layer, leaning one block against the next. Keep the interior wall smooth so moisture can run down the side of the wall, instead of dripping from the ceiling. Include a vent hole to allow for better circulation.

Does an igloo need a vent?

It is vital to make at least one airhole in the roof to avoid suffocation. The igloo will get very warm inside with heat from your body, even if it is cold and windy outside. Without ventilation, lethal carbon dioxide will build up.

How does the smoke get out of an igloo?

Because the door of an igloo is at the bottom of the structure and features at least one right angled piece of tunnel to crawl through, the powerful, freezing cold Lapland winds can't blow directly into the living space. And the little hole cut into the top of the curved roof lets smoke from the fire escape safely.

How do they prevent carbon monoxide poisoning inside igloos?

No carbon monoxide detectors were required, but some igloos have a small hole cut into the side of the blocks of snow, so as to allow a little air to enter through the hole in the side of the igloo and escape through the top hole. This helps to reduce the carbon monoxide concentration.

Does an igloo have a hole in the top?

The entrance for the igloo is usually at the bottom, and includes at least one right angle, which keeps the high winds from blowing straight into the igloo and chilling the residents or blowing out the fire.

Why do igloos not melt?

Igloos are built out of bricks of ice. Unlike solid ice, which is a poor insulator for heat, all the compressed snow has more air pockets, making it a perfect insulator. All the cool air in an igloo goes to the bottom part and stays there. This means the upper area of the igloo remains warm.
