Adding insulation to your attic, basement or crawl space is one of the best ways to improve energy efficiency in your home. The R-value measures how well certain building insulation materials, such as insulation, can resist heat. The higher the R-value, the greater the insulation, therefore insulation with a higher R-value will perform better than insulation with a lower rating.
Remember that during insulation installation, the proper insulation can reduce your heating and cooling costs by 30% and may make you eligible to receive a federal tax credit.
