Quick Answer
To block drafts in a winter shelter, use a combination of insulating materials, seal gaps with caulk or rope, and create a windbreak with snow or branches. This will help maintain a stable internal temperature. Additionally, use tarps or plastic sheeting to cover windows and doors.
Sealing Gaps and Cracks
When building or occupying a winter shelter, it’s crucial to seal gaps and cracks to prevent cold air from entering. Use caulk or rope to fill any openings around doors, windows, and vents. For larger gaps, use snow or branches to block the opening. For example, pack snow around the edges of a door to create a seal, or use a bundle of sticks and leaves to block a gap in the wall.
Insulating the Shelter
Insulation is key to maintaining a stable internal temperature in a winter shelter. Use insulating materials like leaves, grass, or pine needles to line the walls and floor. For example, pile 2-3 inches of dry leaves against the walls to create a layer of insulation. You can also use a tarp or plastic sheeting to cover the roof and walls, creating a warm and dry space.
Creating a Windbreak
A windbreak can help reduce the impact of harsh winter winds on your shelter. Create a windbreak using snow or branches by piling snow around the shelter or constructing a fence using sticks and rope. For example, build a fence 3-4 feet high around the shelter using 10-15 sticks, spaced 2-3 feet apart. This will help block wind and maintain a stable internal temperature.
