Foil-Backed Bubble Wrap
Provides thermal insulation for heat retention.
Problem Statement
Many homeless individuals lack access to reliable shelter that protects against rain, cold temperatures, and wind. Existing temporary shelters can be expensive, slow to set up, or require storage space. This project focuses on designing a 6 × 4 × 4 ft insulated tent that is affordable, weather-resistant, and easy to build using accessible materials.
Background Research
Research into emergency shelters shows that insulation and moisture control are two of the biggest factors in survival and comfort.
- Foil-backed bubble wrap improves heat retention by up to 70%.
- PVC pipe is lightweight, strong, and widely available.
- Tarp flooring prevents moisture transfer and reduces heat loss.
- Construction adhesive bonds materials without specialized tools.
Materials Used
Construction Adhesive
Waterproof adhesive used to secure insulation.
Schedule 40 PVC Pipe
Lightweight, durable structural frame.
Heavy-Duty Tarp
Prevents moisture transfer from the ground.
Testing & Data
| Condition | Inside Temp (°F) | Outside Temp (°F) |
|---|---|---|
| Without insulation | 82° | 75° |
| With insulation | 78° | 72° |
Result: The estimation for the increased internal temprature is 6-7°F.
Final Design
- Cut PVC pipes into frame lengths.
- Assemble base and top frame.
- Add vertical supports.
- Attach insulation panels.
- Install tarp flooring.
- Add ventilation and flap door.
