Quick Answer
To maximize shade in a desert, use reflective materials such as aluminum foil or Mylar sheets to deflect the sun's rays. These materials can be applied to a shelter's exterior, interior, or even buried underground to trap cool air. This technique can lower the internal temperature by up to 20 degrees Fahrenheit.
Choosing Reflective Materials
When selecting reflective materials for your desert shelter, consider the durability, weight, and ease of application. Aluminum foil is inexpensive and lightweight, but it may tear or puncture easily. Mylar sheets are more durable and can withstand harsh desert conditions, but they may be more expensive. A good option is to use a combination of both materials, applying aluminum foil to the shelter’s exterior and Mylar sheets to the interior.
Applying Reflective Materials Strategically
To maximize the effectiveness of reflective materials, apply them strategically to the shelter’s design. Cover the south-facing walls and roof with reflective materials to deflect the sun’s rays during the hottest part of the day. Apply materials to the shelter’s interior to trap cool air and prevent heat gain. Consider burying reflective materials underground to trap cool air and provide additional insulation.
Additional Tips for Desert Shelter Building
When building a desert shelter, prioritize using natural materials such as sandbags, branches, and rocks to insulate the structure. Apply a layer of sand or dirt to the shelter’s exterior to provide additional insulation. Consider building the shelter below ground level to trap cool air and reduce heat gain. By combining these techniques with reflective materials, you can create a cool and comfortable shelter in even the harshest desert environments.
