UnedPodMoisture and mould in a container home: causes and prevention
Mould is the most common complaint in poorly built container homes. It is almost always caused by moisture that condenses on cold surfaces and stays there. The fix is design, not just cleaning.
Where moisture comes from
- Cooking, showers and drying clothes indoors.
- Rain penetrating the roof, the cladding or the windows.
- Ground moisture rising through an uninsulated floor.

Open in 3D →Why steel is a problem
Steel is very cold in winter. Warm, humid air condenses on it when the wall has no insulation or vapour control on the warm side.
Prevention
- Continuous insulation and a vapour barrier on the warm side.
- Extract fans in the bathroom and kitchen.
- Controlled ventilation with heat recovery.
- Sealed roof and window details.
Read the guide to condensation and the ventilation guide for the details.
Plan the wet rooms and the ventilation in the UnedPod configurator before the walls are finished.
