Technical and Economic Analysis of CFC-Blown Insulations and Substitutes for Residential and Commercial Construction

摘要

The thermal performance and economics of rigid foam insulating materials containing chloroflourocarbons (CFC's) 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.
