A higher insulation R rating typically translates to improved climate management and energy efficiency in your home. A greater R-value for insulation usually translates to a higher price. Check the R-value per inch of thickness provided on the manufacturer's website for each kind and material of insulation.

R-13 to R-23 are standard exterior wall insulation requirements, whereas R-30, R-38, and R-49 are frequent ceiling and attic insulation recommendations.
