N2 - Developing new insulation materials having a thermal resistivity greater than 69 m K/W (10 hr ft2 °F/Btu/inch) can be appealing for building envelope retrofit and construction of new buildings. Multiple institutions are involved in the development of innovative insulation materials with high thermal resistivity. However, these projects have struggled in the development of new materials due to the difficulty associated with the measurement of small sections of high thermal resistivity materials. As new materials are being developed, the size of each test specimen impacts the cost of development. Given the lack of a reliable method to measure the thermal resistivity on small samples of such materials, we evaluated experimental techniques that can be improved to satisfy the need for testing small sections of high thermal resistivity materials and developed standardized test methods to enable the rapid thermal evaluation of advanced insulation materials. This paper presents the study results and potential techniques for fast, accurate, and reliable effective thermal resistivity measurement on small samples of insulation materials.
