To obtain maximum energy conservation and minimum annual operating costs, insulation thickness should be based on what the authors call Economic Thickness of Insulation (ETI). ETI is calculated by using a series of formulas (one for each type of surface to be insulated). What makes this handbook so valuable is not just its presentation of the ETI formulas but the handy, easy-to-use charts and tables derived from them.
