SUMMARY

The discussion focuses on the challenge of obtaining thermal conductivity values from K-Factor and density for insulation materials, which are essential for modeling in finite element programs. Participants highlight that no existing software directly utilizes K-Factor, necessitating conversion to thermal conductivity measured in Watts/[m*C]. Additionally, the conversation addresses the difficulty in finding specific heat values for insulation materials, which are crucial for transient thermal modeling. An online calculator from Engineering Toolbox is recommended for converting K-Factor to thermal conductivity.

PREREQUISITES
  • Understanding of thermal conductivity and K-Factor definitions
  • Familiarity with finite element modeling techniques
  • Basic knowledge of specific heat and its relevance in thermal analysis
  • Experience with online calculators for thermal properties
NEXT STEPS
  • Research the conversion formulas between K-Factor and thermal conductivity
  • Explore finite element analysis software that incorporates thermal properties
  • Investigate suppliers that provide specific heat data for insulation materials
  • Learn how to use the Engineering Toolbox thermal conductivity calculator
USEFUL FOR

Engineers, thermal analysts, and construction professionals seeking to optimize insulation performance and accurately model thermal behavior in materials.

A lot of insulating materials only list the density and K-Factor. Is there a way to obtain thermal conductivity (Watts/[m*C]) so it can be modeled in say finite element program. No software i know of can work with K-Factor. And for a bonus question. can you also calculate the specific heat of a material from these values for the same reason - transient thermal modeling (needs specific heat). Try finding insulation on the web that lists specific heat of the material. I have yet to find a supplier that has specific heat information about their product readily available.
