Are Shipping Containers Heat Resistant?

How Heat Resistant Are Shipping Containers?

Key Takeaways

• Shipping containers can be made heat-resistant through proper insulation and ventilation.
• Different insulation materials like styrofoam, spray foam, and rolled batt are effective in varying climates.
• Reflective paint and coatings can significantly reduce heat absorption in shipping containers.
• Conexwest fabricates custom shipping containers with the option to add heat-resistant insulation.

Why Heat Resistance Matters For Shipping Containers

1. Protecting Contents From Heat Damage: Heat-sensitive items like electronics, perishable foods, and certain chemicals require proper insulation and temperature control to prevent spoilage or malfunction.
2. Preventing Deformation and Discoloration of the Container: Exposure to high temperatures can cause discoloration and deformation, compromising the structural integrity of the container.
3. For Safe Working Conditions: Heated shipping containers can have high surface temperatures that pose a burn risk to workers handling or loading the containers.

Best Practices For Improving Heat Resistance In Shipping Containers

Spray foam improves the insulating properties of shipping containers.

1. Use high-quality insulation materials such as spray foam, styrofoam panels, or mineral wool to minimize heat transfer and maintain stable internal temperatures.
2. Ensure proper airflow through vents or windows to prevent heat buildup and humidity.
3. Apply reflective coatings like Super Therm® or Sunshield to the exterior of the container to reduce solar heat absorption.
4. Install integrated heating and cooling systems as per the needs of the cargo being transported.
5. Consider custom roofing solutions to reduce direct sunlight exposure.
6. Implement temperature and humidity monitoring systems to keep track of conditions inside the container and make adjustments as necessary.
7. Check that doors and openings are well-sealed to prevent air leaks that can compromise temperature control.
8. For stainless steel containers, consider using thermal jackets or insulating covers to prevent burns and improve heat retention efficiency.
9. Position containers in shaded areas or use canopies to reduce direct exposure to sunlight.
10. Conduct regular inspections and maintenance of insulation, seals, and climate control systems to check they are functioning effectively.

Use Cases Of Heat-resistant Shipping Containers

1. Transporting Perishable Goods: Shipping containers with heat-resistant features are essential for transporting perishable items, such as food and pharmaceuticals.
2. Chemical Storage: Heat-resistant shipping containers can be modified to safely store and transport chemicals which require strict temperature control to prevent hazardous situations. 
3. Mobile Offices and Living Spaces: Proper insulation and heat management solutions can create a comfortable environment if the container is used as a mobile office or home studio. 
4. Temporary Storage Solutions: In construction or event management, heat-resistant shipping containers can be used as temporary storage units for sensitive equipment or materials that may be affected by heat.
5. Wine and Beverage Transport: Heat-resistant containers maintain the optimal temperature for wine storage to preserve flavor and quality.
6. Disaster Relief and Emergency Shelters: Heat-resistant shipping containers can be deployed as emergency shelters in disaster-stricken areas.

Frequently Asked Questions (FAQs)

Are shipping containers automatically heat-resistant?

Shipping containers are not automatically heat resistant. To make a shipping container heat-resistant, you need to add insulation, ventilation, and possibly reflective paint or coatings.

What happens to shipping containers in extreme temperatures?

In extreme temperatures, shipping containers can experience significant internal heat buildup, which can damage items like food, electronics, and chemicals. Moisture can also accumulate inside the container, leading to condensation and further damage.

What types of insulation work best for shipping containers?

• Styrofoam: Ideal for non-heat-producing assets like records storage or animal feed storage. It's fast and easy to install.
• Rolled Batt: Commonly used in residential conversions due to its good thermal resistance and ease of installation.
• Spray Foam: Provides excellent coverage and seals gaps effectively - ideal for climates with extreme temperature fluctuations.

Can heat-resistant shipping containers be used in all climates?

Yes, heat-resistant shipping containers can be used in all climates. For example, in a hot climate, spray foam insulation and reflective paint keep the interior cool. In a cold climate, rolled batt insulation and an HVAC system are used to maintain a warm environment.

What are Conexwest’s rental terms for shipping containers?

Our rental terms work on a 4-week basis with automatic renewal. You can choose from various container sizes ranging from 10ft to 45ft in length.
