Insulation is needed to keep a colony warm. Aerogel or plastic foam may be utilized for insulation. Regolith may be heaped over buildings to keep in heat. Mineral wools, spun from local resources, may provide a lower tech alternative insulation. Fiberglass, a type of mineral wool, is commonly used as insulation on Earth. Arsenic is a mineral that can be used as a heat tolerant insulation, but is toxic to life.
- What is the heat transition coefficient of regolith, aerogel and other materials?
- What can be produced in-situ with low energy consumption?
