Ashrae U Value Table. Hi Appendix A Tables 31 in ASHRAE 901 has information on the relation between equivalent U-values and R values of wall sections. R-Value Assembly Maximu m Insulatio n Min.

Wall or roof exposure orientation.
Additionally a building system U-value may be determined by thermal testing and thereby rated as a maximum assembly U-value. Explore alternatives to the prescriptive wall insulation more CI and less cavity R-value etc Determine U-factor input to energy model or energy rating programs Must use code-compliant. Industrial type buildings 0057 175 Steel-Framed ie. U-value of course is the inverse of the R-value so a maximum assembly U-value of 01 would be an approximate minimum R-value of 10.
