Stephan writes from Abingdon, Maryland: “When attic flooring is installed and compresses loose fill insulation, does is significantly decrease the R-Value?
Fiber glass insulation works on the principle of trapped air pockets. By compressing fiber glass insulation, you decrease the amount of air trapped in the material. For example, compressing R-19 into a 2×4 wall will give you an R-13 value. If you click through to the chart you will see what that it is for insulation compressed in a wall cavity but the same principle applies for attic insulation.
