Insulating your home is an essential step in ensuring your comfort and energy efficiency. The insulation rating is measured in R-values per inch of thickness, and this value indicates how well a type of insulation can prevent heat from entering or leaving the house. The R-value of insulation varies depending on the type, thickness, and density of the material. Generally, a higher R-value means better climate control and energy efficiency, but it also usually means a higher price.
Depending on where you live and the part of the house you are insulating, typical recommendations for exterior walls are R-13 to R-23, while those for roofs and attics are R-30, R-38, and R-49. The US Department of Energy (DOE) has provided ranges for recommended insulation levels. Michigan is divided into three climate zones, and each zone has its own minimum R-value requirements. The absolute minimum R-value for attic insulation across the country is R-30, and the recommended maximum values range from R-49 to R-60 for zones 1 to 3.At TCI Remediation, we use blown cellulose insulation to ensure that your home has the right type of attic insulation for maximum efficiency and comfort. If your home has drafts or your utility bills are rising, attic insulation is a great place to start.
Search for your area on the map and then use the insulation R-value table to determine the level of insulation you need to properly insulate your attic, walls, floors, and mezzanines. If your current attic insulation isn't wet from roof damage and doesn't have mold, it will serve as a base for additional attic insulation, which will increase the R value. When the insulation is installed in a cavity smaller than the thickness of the label or the insulation design, the installed R-value of the insulation must not be less than the R-values specified in the table. Understanding the meaning of the R-value of insulation is one of the most important first steps when adjusting your home's insulation.
Under Joe's leadership, Attic Construction has become the largest leading attic restoration company in San Diego, Orange County and Phoenix. Insulating your home is an important investment that can save you money in energy costs over time. Knowing what type of attic insulation you need and what its corresponding R-value should be is essential for making sure that you get maximum efficiency from your home's insulation system. With this guide, you can make sure that you have all the information you need to make an informed decision about what type of attic insulation is best for your home.
