Every component of the roof (i.e.: GI sheet, concrete, insulation, air space, sheetrock/gypsum, acoustical tiles, etc.) has a given R-value based on its thickness. Basic HVAC data reference books will provide the R-value or the K-value for most construction materials. If you do not have any reference books, we will be happy to tell you the R-value of materials you are considering.
