- Abstract
- A new study by the staff of the Buildings and Fire Research Laboratory of the National Institute of Standards and Technology (NIST) promises a better approach to defining what is acceptable performance for low-sloped roof membranes. The report, NISTIR 4638, proposes a performance approach for developing criteria for the selection and use of low-sloped roof membrane applications. This article, edited for space and brevity, is excerpted from the report. The majority of low-sloped roof systems perform satisfactorily. Nevertheless, on the average, the early failure rate for low-sloped roofs is considerably higher than for other major components of a building.
