Quick Answer
For temporary wind resistance, use materials like plywood sheets, oriented strand board (OSB), or 1/2-inch thick exterior-grade plywood, which can withstand moderate wind loads. Secure them with 3-inch galvanized lag screws spaced 16 inches apart. You can also use natural materials like sandbags filled with soil or gravel.
Securing Walls and Roofs
When securing walls and roofs, use a combination of screws, nails, and wire mesh to create a solid barrier against wind-driven debris. For plywood sheets, use 3-inch galvanized lag screws spaced 16 inches apart, with an additional screw at each corner. For roof areas, apply a 2:1 ratio of screws to nails, with screws at the peak and nails along the eaves.
Wind-Resistant Ties and Fasteners
To prevent roofs from lifting or walls from collapsing, use wind-resistant ties and fasteners like 1/2-inch diameter steel rods or 3/8-inch aluminum rods. Drill holes 1 inch deep and 1 inch apart, then insert the rods and secure with 2-inch galvanized lag screws. This will create a strong and stable structure that can withstand high wind loads.
Sandbags and Natural Barriers
For additional wind resistance, use sandbags filled with soil or gravel to reinforce walls and foundations. Fill sandbags to 2/3 capacity to ensure they can be easily stacked and secured. Place them along the perimeter of your shelter, with the filled side facing outward to prevent erosion and structural damage.
