This tool tackles the #1 nightmare of container builds: “Container Rain.” It simulates the physics of a steel box in winter, visualizing how warm interior air hits the freezing cold steel shell to create indoor rain.
It demonstrates why Closed Cell Spray Foam is the industry standard for containers, as it is the only method that seals the corrugations to prevent hidden mold growth behind your walls.

Why standard insulation fails in shipping containers.
1. Environment
2. Insulation Method
The Corrugation Trap
Shipping container walls are wavy. Rigid foam or batts span the high points, but leave gaps in the valleys. Warm, moist air gets trapped in these gaps, hits the cold steel, and condenses.
Closed Cell Spray Foam expands to fill every nook of the corrugation. It bonds directly to the steel, eliminating the air gap. No air touching cold steel = No condensation.
