Plain Talk About Condensation and Radiation Below Metal Roof Assemblies
Abstract
During recent decades an increasing number of users have chosen metal roofing for various commercial, industrial and institutional buildings. Because of several advantages, construction of new pre-engineered and "hybrid" buildings has outpaced low-rise, nonresidential conventional construction since 1984. Unfortunately, some of these advantages may give rise to certain disadvantages in comfort, durability and operating costs (7).
This paper provides a brief historical overview of common metal roof insulation methods as well as recent innovations for low cost/no cost performance enhancements. Following is a discussion of current industry trends and design considerations for those seeking to control the combined effects of conduction, convection, radiation and moisture migration in individual roof assemblies.
