Having high quality insulation in your residential or commercial building's walls is critical to comfort and energy efficiency. Unfortunately, many North American buildings today contain insulation that doesn't meet standards. Often, insulation was improperly installed during construction. In some cases, insulation has settled over time, reducing R-value and creating air leakage that further reduces the impact of the insulation.
