Soap based thermal insulation: A sustainable alternative to petroleum

The thermal insulation market is dominated by petroleum insulations. A gap has been 
identified for the manufacture of “green” insulations. These insulations must perform to the 
same levels of heat transfer resistance as their petroleum based counterparts. 
Modern petroleum derived insulations can be carcinogenic, toxic to manufacture and release 
toxins as they degrade. The majority are not environmentally friendly. The aim of this 
research is to create an insulation that combats the above points and addresses the gap 
between sustainable and non-sustainable insulations. 
This research will address the uncertainties in the alternative insulation validation process, 
achieved through experimental research. Soap will be manufactured from lye, animal fats and 
oils and aerated to produce soap insulation. These manufactured soap samples will be tested 
in both laboratory and real-world settings. Soap insulation could be a useful addition to low 
environmental impact insulation and create a foundation for further research to build off.
