Abstract:
Between 1985 and 1995, approximately 750,000 multi-family housing units experienced roofing problems due to fire-retardant-treated (FRT) plywood sheathing failure (Figs. 1-3). The problem is caused by excessive exposure to solar radiation.

Research at the USDA Forest Service, Forest Products Laboratory (FPL), from 1988 to 1999 resulted in more than 20 technical papers and three national standards. The standards, developed by the American Society for Testing and Materials (ASTM) and American National Standards Institute (ANSI), form the scientific/technical basis for new performance-based qualification requirements for commercial FRT plywood roof
