Description/
Abstract A wide variety of rigid-board types of insulations are currently manufactured for use under membranes of built-up roof (BUR) systems on buildings with low slope roofs.^The US Air Force currently specifies one type of BUR insulation in reroofing its facilities within the continental US.^The primary goal of this study was to develop an evaluation method for future Air Force use in selecting rigid-board insulations.^The method was to include roof performance requirements for a long-lived system with life cycle costs (LCC) comparable with the currently specified insulation - fibrous glass.^Insulation thermal resistance values up to R-33 (ft/sup 2/.h./sup 0/F/Btu) were included in the range of investigation.^This report describes the development of an LCC-based evaluation method for long-lived BUR insulations.^The study emphasizes general performance requirements for a long-lived BUR system, and presents the results of 20-year energy costs and general recommendations for insulations on a comparable economic (LCC) basis over a range of R-10 to R-33.^The economic justification of very high (up to R-33) insulation levels under BUR membranes is also evaluated on the basis of optimum economic levels and is found to have little or no justification above an R-25 level.
