Ring’s End is committed to helping its customers―both professional and non-professional―build energy-efficient homes and buildings. A key to that process is choosing and installing the proper insulation for each application. Insulation is measured by its R-Value or its resistance to thermal conductivity. The higher the R-Value, the greater the resistance to heat passing through. Insulation that is sprayed in or blown-in should be supplied and installed by specialists. Ring’s End offers a wide variety of insulation that can be installed without special skills or equipment.
