Spray Foam Genie Greensboro – How to Insulate Your Attic
A well-insulated attic is a great way to save on your air conditioning costs. It is an important investment that will pay off quickly with a lower energy bill. There are many insulation options, including loose-fill, fiberglass batts and rolls, and spray foam insulation. Each type of insulation has its own unique application and benefits.Source :https://www.sprayfoamgenie.com/greensboro-and-high-point-nc/
If you are looking for a budget-friendly option, fiberglass batt or roll insulation is the best choice. It is pre-cut into long sheets and is easy to fit in between the framing members (such as joists and trusses) in an attic. Fiberglass batt and roll insulation is also very effective at resisting heat flow and is relatively inexpensive compared to other types of insulating material. In addition, it doesn’t promote mold growth and is resistant to fire.

Another good choice for an attic is mineral wool insulation, which is composed of natural materials and is more moisture-resistant than fiberglass. Like fiberglass, mineral wool is also very effective at resisting heat flow. It can be installed as a blanket or in between joists using an insulation blower. Unlike fiberglass, however, mineral wool is non-flammable and does not support the growth of mold or mildew.
If your attic already has a blanket or loose-fill insulation, it is important to determine its R-value before installing more. You will want to add additional insulation if the current R-value is lower than recommended for your climate zone. When adding blown-in fiberglass, you should first calculate your desired R-value for the entire attic and mark it on the joists with a marker. When adding a new layer, cut the fiberglass batts 1-inch less than your measurement (for example, if the center of your joist is 12 inches, you will need to cut your insulation to 11-inches).
