How is the R-Value determined?
The FTC (Federal Trade Commission) requires reflective insulation R-Values to be determined by using the ASTM C 1224 test. This test determines an R-Value for the entire assembly. The assembly consists of two 2"x4" wood studs 16" on center, 1/2" plywood deck on top, and the insulation installed at the mid-span of the 2"x4". The reflective airspace is critical to creating R-Value. The greater the airspace, the greater the R-Value.
How can other reflective insulation have a greater R-Value?
Some suppliers still use the ASTM C976 test, which allows them to place the insulation on the outside edge of the 2"x4", thus creating a 3-1/2" air space. In July of 2003, the FTC ruled to no longer accept the ASTM C976 test as a "fair and accurate" test in establishing R-Values.
