Is It Advisable to Use a Tarp Inside an Igloo?

Moisture Accumulation and Condensation

In traditional Inuit igloos, a layer of snow or a waterproof cover is used to prevent moisture from entering the shelter. However, when a tarp is used inside an igloo, it can trap warm air and moisture, leading to condensation on the tarp and surrounding walls. This can be particularly problematic in cold, humid environments where the temperature difference between the inside and outside of the igloo is significant.

Ventilation and Insulation

To mitigate the effects of moisture accumulation, it’s essential to ensure proper ventilation within the igloo. This can be achieved by creating small openings or vents in the walls or roof, allowing for the exchange of air and moisture. Additionally, using a tarp with a breathable material or incorporating insulating layers between the tarp and the igloo walls can help to reduce condensation.

Alternative Options

In some situations, using a tarp inside an igloo may be necessary, such as in areas with limited snowfall or when building an igloo in a warm environment. In these cases, it’s crucial to use a waterproof and breathable tarp, such as a silnylon or nylon tarp, and to ensure proper ventilation and insulation within the shelter. This can help to minimize the risks associated with moisture accumulation and condensation, and create a more comfortable and safe indoor environment.
