Insulation R-values measure how effectively insulation can resist the flow of heat. The higher the R-value, the greater the resistance, indicating better insulation material for a home.
What is the best R-value for my insulation?
In southern areas, insulationranging from R30 to R60 and floor insulation betweenR13 and R19In northern states, attic insulation with R49 to R60 ratings and floor insulation in the R25 to R30
Formula Of Calculate R-Value Insulation
In what way do you determine a structure's R-value?
You can calculate it by combining the R-values of each component that provides a uniform and continuous layer within the structure.
