Thermal Performance

摘要

Thermal resistance (R-value) of straw bale (SB) walls has been tested for 20 years, with the most reliable tests indicating R-values ranging from R-33 to R-50 (R per inch values of 1.46 to 2.25) for walls with three-string (22.5 by 16 in.) bales. The range results from variations in bale orientation, bale density, construction practices, and moisture content.
