Why are there different Total R-Values for different applications?
Different applications will have different Total R-Values because they take into consideration the R-values of each of the building elements (tiles, metal roof, bricks, timber, etc.) as well as the installed conditions of AIR-CELL® Insulation such as width of air spaces. For example, AIR-CELL® Insulation installed into a double brick wall will have a higher Total R-Value than AIR-CELL® Insulation installed into a brick veneer wall because the two layers of bricks in a double brick cavity wall will have a greater thermal mass and higher material R-values than the single layer of brick installed with a stud frame in a brick veneer wall application. The different widths of the air spaces will also provide different R-values.
