Fiberglass insulation is an effective way to improve your home’s energy efficiency by maintaining a consistent temperature, which in turn helps prevent high utility bills. It offers a wide range of R-values, making it possible to meet various energy code requirements for different structures. Also, blown-in fiberglass insulation can be installed over existing batt insulation, increasing the R-value. Fiberglass insulation is an ideal option for those seeking to enhance their home’s energy efficiency and reduce utility expenses.
