APA Performance-Rated Wood Structural Panels as Thermal Barriers for Foam Plastics
Technical Topic
This technical document provides critical fire safety information about using APA performance-rated wood structural panels as thermal barriers when installing foam plastic insulation in building construction. The publication details test results demonstrating compliance with International Building Code (IBC) requirements, specifically addressing the 15-minute temperature rise limitations under ASTM E119 time/temperature exposure conditions.
This publication is designed for: architects, engineers, builders and building code professionals
It covers both the general thermal barrier requirements and the prescriptive exemptions available for roof installations, clarifying the minimum panel thicknesses, edge support requirements, and species specifications needed to meet code standards.
