Consider the design of a new building. The wall type shown above will be used. (If the image is unclear, click here to open it in a new tab.) The thickness of the "mineral wool" exterior insulation (layer '6') is to be determined. This type of insulation has rated thermal resistance R-4.2 per inch ( hr. ft² °F/btu. If the design intent is to achieve a clearfield thermal resistance R-17, what thickness of mineral wool insulation is needed? O 0.5 inches 1 inch 1.5 inches 2 inches 3 inches 4 inches 5 inches
