- Abstract
- Although untreated plywood has given satisfactory performance as roof sheathing for more than 50 years, some fire-retardant-treated plywood products have not performed satisfactorily in recent years. Thermally induced in-service failures have occurred with some fire-retardant-treated plywood roof sheathing. This paper describes the development and evaluation of a new test protocol for screening potential fire retardant treatments for plywood that is continuously or periodically exposed to elevated temperatures.
