What R Value is Right for You?
R Value is defined as the ability of an insulating material to reduce heat flow. A higher value means a greater reduction in the exchange of heat. By meeting the guidelines set out by the U.S. Department of Energy, you can expect to save up to 20% on your home’s heating and cooling costs.
Adding insulation to attics, floors, crawl spaces, and accessible basement rim joists is a great way to get started. Reducing costly air leaks makes for a more comfortable, energy efficient and eco-friendly house. Suggested R Value is based on geographic location and the regional weather associated with it.
