When insulating a shipping container, such as those used at storage facilities like Yellowhead Storage, insulating the inside or outside depends on the container’s intended use and the user’s specific needs.
Internal Insulation: Insulating the inside of a shipping container is the most common approach, especially for storage purposes. This method maximizes the container’s structural integrity and its ability to withstand external elements. Internal insulation is typically made from foam panels, fibreglass, or spray foam. It effectively controls the internal temperature and protects the contents from extreme weather conditions. However, internal insulation reduces the interior space, which might be a consideration for storage needs.
External Insulation: Insulating the outside of a shipping container is less common but can be used in specific scenarios, particularly when the container is being repurposed for living spaces or offices. External insulation preserves the internal space but requires additional weatherproofing and structural support. It can also impact the container’s mobility and aesthetic appearance.
Repelling Condensation
Repelling condensation in storage containers is crucial to protect your items from moisture damage. Here are some effective strategies to keep condensation at bay:
Moisture Control
- Use Dehumidifiers: Place a dehumidifier inside the container to reduce humidity levels. This is particularly useful in areas with high humidity.
- Desiccants and Moisture Absorbers: Use silica gel packs, desiccants, or moisture-absorbing products like DampRid to keep the air dry and absorb excess moisture.
- Waterproof the Container: Ensure the container is sealed and waterproof. Inspect for and repair any leaks, holes, or gaps to prevent water ingress.
Ventilation
- Install Vents: Add vents to the container to promote air circulation and reduce humidity levels. This helps prevent the build-up of warm, moist air that can lead to condensation.
- Use Fans: Place fans inside the container to improve airflow and keep the air circulating, which helps to reduce humidity.
- Open Doors Regularly: Periodically open the container doors to allow fresh air in and let out any accumulated moisture.
