Quick Answer
To insulate a quinzhee for extreme cold, cover the exterior with snow to a depth of 12-18 inches, and then apply a layer of insulating material such as pine needles or dry grass. This will help to reduce heat loss and keep the shelter warm. Finally, add a layer of snow on top to protect the insulation from wind and moisture.
Preparation and Insulation Materials
When building your quinzhee, it’s essential to have the right materials for insulation. Pine needles, dry grass, or small twigs are ideal for this purpose. Avoid using wet or damp materials, as they will only make the shelter colder. It’s also crucial to gather these materials before building the quinzhee, as you’ll need them for insulation. Aim to collect about 2-3 cubic feet of insulation material per person.
Application of Insulation
Once you’ve built your quinzhee, it’s time to apply the insulation. Start by piling the insulation material on top of the shelter, about 6-8 inches deep. Then, use a shovel or your hands to spread the material evenly, making sure to cover the entire surface. This will help to reduce heat loss and keep the shelter warm. Be sure to avoid packing the insulation too tightly, as this can prevent it from doing its job.
Final Protection
The final step is to apply a layer of snow on top of the insulation. This will help to protect it from wind and moisture, ensuring that your quinzhee remains warm and cozy. Aim to add about 12-18 inches of snow on top, depending on the wind conditions. This will also help to create a smooth surface for sleeping or sitting, making your quinzhee a more comfortable shelter.
