Building material R-Values are tested in a uniform laboratory testing method. The problem often lies within the “non-perfect” installation techniques that are commonplace in the construction industry. These 3 slides illustrate a) that there is a Law of Diminishing Returns when it comes to R-Value; b) that a small insulation void or improper insulation installation can greatly reduce the expected R-Value performance of a wall assembly; and c) how those voids are shown via infrared imagery (the camera does not lie).
