Abstract There are different types of traditional materials for insulation in different processes such as: clay, limestone, ceramic foams, among others, used mainly in furnaces and buildings, whose function is to reduce heat and acoustic noise transfer through the structure on which they are installed. Alternatives for insulation with reusable and organic materials are currently being sought. In this work, the physical property of the thermal conductivity of materials such as quartz, glass, bone, and coconut shells were analyzed in order to compare their thermal conductivity measured experimentally with respect to that reported theoretically, and determine if they are suitable for use in the market and also to have a foundation that allows subsequent processes to mix them, giving way to new insulating or refractory materials with better physical properties.
