One of the most important parts of a shipping container home conversion is the insulation. A steel box is fantastic at absorbing the suns heat, and at transferring the cold from the outside to the inside.
There are a few commercially available shipping container insulation kits and you can get shipping container insulation spray foam, but I chose a product with extremely high performance in a compact space.
Polyisocyanurate offers twice the performance of result polystyrene container home insulation, or rockwool insulation, which are both often used as container house insulation.
For the container house floor insulation I've used 50mm, or 2inches, of polyisocyanurate.
For the container house wall insulation I've used 50mm, or 2 inches, of polyisocyanurate.
For the container home ceiling insulation I've used 50mm and a further 25mm of polyisocyanurate.
This is the equivalent of 100mm of regular insulation on the walls and floors, and 150mm on the ceiling.
In my opinion polyisocyanurate is the best insulation for shipping container homes because it adds excellent performance in a very limited space. This is the best insulation for shipping containers in my opinion. The cost to spray foam a shipping container is huge, and whilst polystyrene insulation, the shipping container insulation panels, and rockwool insulation are all cheaper, you either lose a lot more interior space or have half the thermal performance. So if you pay a little more you get a much better result.
