What Is R-Value?
The performance of insulation is typically measured by a common standard known as R-value. The “R” in R-value stands for resistance to heat flow. The higher the R-value, the higher the level of resistance and the greater the insulating power. R-value requirements vary depending on climate and building type as well as local energy codes, which establish the minimum level of insulation needed to create an effective thermal enclosure.
How Much Insulation Is Enough?
The amount of insulation needed varies depending on location, building type and materials. ENERGY STAR, a U.S. Environmental Protection Agency (EPA) program that promotes superior energy efficiency, provides recommended and cost-effective insulation levels for homes across the country based on climate zones and are specified by R-Value. R-Value measures the ability of insulation to resist heat traveling through it, with a higher R-Value indicating better thermal performance. A properly insulated home is a comfortable, efficient home.
The image below shows the different climate zones and the recommended insulation levels for retrofitting existing wood-framed buildings. According to the North American Insulation Manufacturers Association (NAIMA), more than 90% of homes in the U.S. are under-insulated*. Energy Savers has well over a decade of expertise working in Kentucky and Southern Indiana and we have a broad knowledge of the current code requirements. We will be happy to suggest custom-tailored solutions for your needs that will meet or exceed these requirements and help make sure your home isn’t part of that 90%!
