Temperature-Safe Storage and Transport
Insulated Containers
Insulated containers feature thermal barriers within walls, ceilings, and floors to maintain internal temperatures regardless of external conditions. The heavy-duty insulation protects temperature-sensitive goods across New Zealand without requiring constant power.
At SEA Containers, we provide new and used insulated containers that deliver consistent climate control while staying cost-effective, durable, and vermin-proof. Our decades of expertise serving the North Island, South Island and Pacific territories ensures tailored solutions that perform in real-world conditions.

How Do Insulated Containers Work
Insulated shipping containers are standard dry containers modified with thermal barriers, which can be ply-lining, spray foam, or custom insulation kits.
These containers maintain constant internal temperatures by significantly reducing heat transfer between interior and exterior environments.
The multi-layered construction traps air within insulation materials, creating thermal breaks that maintain temperature differentials. This passive insulation works without power, unlike refrigerated containers.
Buying vs Hiring Insulated Containers
Ownership makes financial sense for long-term needs extending beyond 12 months, providing complete control over modifications and placement decisions.
For temporary requirements during events, renovations, or seasonal operations, hiring minimises capital outlay while maintaining operational flexibility.
Insulated Shipping Container Maintenance Tips
Proper maintenance ensures your insulated container delivers optimal performance throughout its service life. Follow these essential practices:
- Regular cleaning with food-grade sanitisers to prevent contamination and extend shipping container lifespan
- Routine inspection of seals and door gaskets to prevent loss of hot and cold air
- Strategic ventilation and proper loading to minimise condensation risks inside the container
- Optimal positioning and scheduled maintenance to reduce energy consumption for powered units
