Plastics Energy and Greenhouse Gas Savings Using Rigid Foam Sheathing Applied to Exterior Walls of Single Family Residential Housing in the U.S. And Canada – a Case Study

This analysis is a case study that examines energy savings and greenhouse gas (GHG) emission reductions resulting from the addition of rigid plastic foam sheathing to the exterior walls of single family housing in the United States and Canada. The widespread use of rigid plastic foam sheathing on exterior walls is relatively recent, spurred by the energy conservation awareness brought on by the energy crisis of the early and mid-1970’s. It possesses excellent structural and insulating characteristics and is considered to be cost effective by most homebuilders today. Its use significantly increases the insulation R-value of walls, and therefore saves energy and reduces GHG emissions.
