- Abstract
- Rigid foam insulation blown with chlorofluorocarbons (CFCs) are among the most thermally efficient materials available for insulating walls and roofs of buildings. While they are more expensive than traditional insulating materials, their usage were space constraints dictate a more efficient insulator have become commonplace. Increasing concern about the effect of CFCs released to the atmosphere may result in restrictions on the availabiligy of these insulation materials. This report evaluates the thermal performance and economics of rigid foam insulating materials containing CFCs and alternative insulation materials that contain little or no CFC. Residential walls (wood-frame and masonry), commercial wall systems (frame, masonry, and curtain wall) and commercial low-slope roof systems are examined in a wide range of climates in the United States to determine the cost effectiveness of rigid foam insulation materials. Economic substitutes for insulation materials containing CFC exist; however, they are not compatible with all types of wall/window and roof systems and thus may make some wall and roof systems impractical.
