Professional Container Conversions
Shipping containers are built for durability, not comfort. Comprising highly conductive corrugated steel walls, they rapidly transfer exterior temperatures to the interior.
Without professional-grade insulation, they act as stifling ovens in the summer and freezing metal boxes in the winter. Furthermore, as internal temperatures fluctuate against the cold steel, severe condensation issues—often termed "container rain"—occur year-round.
Commercial spray foam completely neutralizes the thermal conductivity of the corrugated steel. This chemical application allows standard shipping containers to be rapidly and effectively utilized for high-end site offices, secure document storage, laboratories, pop-up retail spaces, or bespoke modular housing.
Container Conversion Experts
Transforming a steel box into a habitable or secure storage space requires a fundamental understanding of thermodynamics. Our technical team are experts in container conversion insulation. We understand the fatal flaw of DIY methods: simply gluing flat PIR boards to a corrugated steel wall creates trapped air pockets inside the corrugations.
Moisture inevitably accumulates in these voids, leading to hidden, aggressive rust. Our engineered approach ensures the liquid spray foam perfectly fills and matches the deep steel profile, bonding entirely to the metal surface and eliminating the air gaps where condensation thrives.
Why Spray Foam is Superior for Containers
Eradicates "Container Rain"
Forms a complete vapor barrier that protects stored goods, sensitive electronics, and interior fit-outs from devastating dripping condensation.
Follows Deep Corrugations
Liquid foam effortlessly fills and bonds to the deep corrugated profiles of the steel walls, leaving no voids for hidden rust to develop.
Maximum Internal Volume
Containers have strictly limited width. Spray foam achieves incredibly high U-values with minimal thickness, preserving valuable internal dimensions for your fit-out.
Structural Rigidity
The high-density closed-cell foam acts as a structural adhesive, adding significant rigidity to the walls and minimizing flex during transport or heavy craning.
