Quick Answer
To seal gaps in igloo walls for warmth, use a combination of snow blocks, a shovel, and a sturdy stick to create a tight seal. Start by packing the gaps with soft snow, and then use a stick to compact it firmly. For larger gaps, use snow blocks to fill in the space.
Filling Gaps with Snow Blocks
To create snow blocks, start by cutting a block of snow from a larger area using a shovel. The ideal block size is about 6 inches thick, 8 inches wide, and 12 inches long. Hold the block against the gap and gently tap it into place with a sturdy stick until it’s firmly set. Repeat this process for each gap in the igloo wall.
Compacting Gaps with a Shovel
For gaps that are too large for snow blocks, use a shovel to pack soft snow into the space. Hold the shovel vertically and slowly push it into the gap, packing the snow tightly as you go. Use a sturdy stick to compact the snow firmly and create a solid seal.
Additional Tips for a Tight Seal
To ensure a tight seal, make sure to pack the snow firmly and evenly into the gaps. You can also use a layer of firmer snow on top of the gaps to protect them from melting and settling. Additionally, consider using a layer of insulation, such as animal hides or grasses, to help keep the igloo warm and dry.
