UnedPodContainer home insulation R-value: what the numbers mean
R-value measures how well a material resists heat flow. For a steel container home, the number on the insulation packet is only part of the story, because the steel bridges through the wall.
What R-value means
A higher R-value means better resistance. Values add up across layers, but a continuous layer matters more than a high number on a broken layer.

Steel studs and corner posts conduct heat around the insulation. Continuous insulation on the outside or inside reduces the effect.
Choosing a target
- Mild climates need less insulation than cold climates.
- Roofs usually need more insulation than walls.
- Floors over an air gap need insulation to stop cold rising.
Check the local code
Energy codes give minimum values for each element. Ask your building office for the table that applies to your climate zone.
The insulation guide explains the layers, and the UnedPod configurator lets you change the wall build-up and see the estimate change.
