*Please consult ASTM E136 and ASTM E84 for information concerning the test methods and measures for combustibility and flame spread. For information concerning the UL 790 and UL 1256 classifications for DensDeck® Roof Boards, consult the applicable UL certifications directory. Please note, however, that the performance of a roof depends on all components used in the roofing assembly and how the components interact. Passing a fire test in a controlled laboratory setting does not mean that a particular product or system will necessarily provide the same resistance or protection in an actual fire.
