Class A Fire-Rated Roofing: Understanding Roof Ratings
Roof fire ratings are established by test methods to ensure that certain standards are formalized to protect human life and property. The American Society for Testing and Materials (ASTM) Standard E108 is one such test method. Materials are classified as a Class A, Class B or Class C Fire rating through this method.
ASTM E108: Decoding Class A, Class B and Class C Fire Ratings
Class A is the highest, meeting stringent requirements, whereas Class C is the lowest. ASTM E108 outlines three critical criteria for Class A fire rating:
- Flame spread resistance – Class A fire-rated roofing material must demonstrate the ability to resist spreading flames on the surface. This provides a crucial line of defense during an encounter with fire.
- Fire penetration resistance – Any Class A roof must resist fire penetration from the exterior to the underside of the roof deck, ensuring comprehensive protection.
- Intermittent flame resistance – Class A roofs must resist intermittent flame exposure, further enhancing fire-resistant properties.
