Insulation Guide
If there is one part of a container home you can't afford to get wrong, it is insulation. Steel is a superb conductor of heat. An uninsulated container is an oven in summer and a fridge in winter, and in a Tasmanian winter the inside face of the steel will drop below the dew point of the air inside. That is when condensation forms, drips, soaks your insulation and starts rust from the inside out.
Good insulation in a container is really about three things working together: keeping heat in (or out), stopping warm moist air from reaching cold steel, and breaking the thermal bridges that steel creates. This guide walks through each one and the main ways to do it.
