Attic insulation helps your home stay cool in the summer and keeps you from losing heat in the winter. However, various materials are used for insulation, and some do a better job of insulating than others. Learning about the different insulation options will help you make the right decision for your home.
What you need to know about R-value
The R-value measures the insulating materials’ thermal resistance. Materials with a higher R-value are more effective at preventing heat loss and retaining cool air. When shopping for insulation, you want to know the material’s R-value as well as your home’s R-value. Your home’s R-value is determined by the Department of Energy and is based on your home’s location. Having this information helps you figure out what materials provide the best insulation for your situation. Most attics can get by with insulating material between R-30 and R-49. However, if your home is in a colder climate where you need more insulation in winter, you might want to consider installing insulation with an R-60 value.
Most popular insulation materials
When you think of insulation, what’s the first thing that comes to mind? Is it the rolls of fiberglass insulation that fit between beams and joists? This insulation type is called blanket insulation. It’s available in rolls or batts and comes in materials besides fiberglass, such as mineral wool and natural fibers. Blanket insulation works best in areas where there are little to no obstructions.
Loose-fill insulation is another popular type that’s ideal in areas where headroom is limited, or there are multiple obstructions, such as cross-beams and vents. The insulation can be blown over existing insulation, and cellulose loose-fill insulation is the most effective. However, if you’re concerned about moisture in your attic, you might want to avoid loose-fill as it’s prone to getting moldy.
If you’re looking for the most effective insulation with the highest R-values, consider spray foam insulation. This type of insulation isn’t cheap, but it serves as an effective air and moisture barrier, expanding to fill gaps and provide outstanding year-round insulation for your home. Spending a little more for top-rated insulation not only lowers your energy costs but also increases your home’s value. Many homeowners find they achieve a high return on their investment when they go to sell their homes in the future.
