Save more than energy. According to the U.S. Department of Energy, one third of the energy used in commercial buildings is devoted to heating and cooling. That is why it makes good business sense to maximize the insulation in your building(s) to achieve greater energy savings and reduce heating and cooling loads.
Heat moves into, out of and through your home or building in four ways: by conduction (which R-value measures), and by convection, radiation, and air infiltration (none of which R-value measures). A superior insulation system will have a high R-value (prevent heat transfer via conduction), will be pneumatically or spray applied, fully filling the building cavity (preventing heat loss via convection) and will be dense (preventing heat loss via air infiltration and radiation). By comparison, the most widely used insulation material, conventional fiberglass batt, only helps prevent conduction.
