Each insulation system has specific advantages The relative eco- efficiencies of these svstems are most impacted by the air emissions and the installed cost. SPF has the advantages of l low installed cost, non-HCFC blowing agent, and the least total system material. EPS and Polyiso use non-HCFC blowing agents and are the lightest insulation materials which translates into environmental advantages XPS uses an HCEC blowing agent, high quantities of insulation material and total system material. It will become more efficient once the switch non-HCFC blowing agents occurs insul ation advantades systems HCFO
