Shipping container answer

How do you insulate a shipping container?

Common approaches include spray foam, rigid foam and framed batt systems. The best choice depends on climate, fire and finish requirements, available interior width, utility routing and whether the space holds people or products.

Avoid hidden condensation

Steel changes temperature quickly. Gaps and poorly placed vapor layers can allow warm, moist air to reach cold metal and condense behind the finished wall.

Protect usable space and openings

Interior assemblies reduce clear width and height. Coordinate insulation thickness with doors, windows, shelving and the working dimensions on the container sizes page.

Occupied spaces need a complete envelope

Office conversions also require code-compliant finishes, heating and cooling, ventilation and safe electrical work. Insulation is one part of the system.

Before specifying a system, review condensation control and whether a mobile office better serves occupied use.

Put these details in the request:
  • Climate and indoor use
  • Air and vapor control
  • Fire and finish requirements
  • Lost interior dimensions
