Evaluated to the following...
The roof covering systems in this section have been evaluated for external fire resistance Classifications A as outlined by the following test methods:
- ASTM-E108 - American Society for Testing & Materials 'Standard Test Methods for Fire Test of Roof Coverings'
- CAN/ULC-S107 - Underwriters' Laboratories of Canada 'Method of Fire Tests of Roof Coverings'
- UL-790 - Underwriters' Laboratories Inc. 'Standard for Tests for Fire Resistance of Roof Covering Materials'
Each system listing identifies the deck substrate as either non-combustible or combustible. Systems evaluated for combustible decks will provide the same ratings when applied over non-combustible decks. Unless otherwise noted in individual listings, combustible decks shall be sheathed with a minimum 1/2" veneer plywood or minimum 7/16" non-veneer APA rated sheathing panel (oriented strand board panels, structural particleboard panels, composite panels or wafer-board panels) or 3/4" thick solid wood sheathing boards. The component materials of each system must be applied in the order in which they are listed. All components of the system must be listed for external fire exposure by an agency acceptable to the AHJ.
Some Roof Covering Systems have been evaluated for other performance characteristics, in addition to external fire exposure. Where applicable, such additional performance characteristics are noted within the specific listing.
In all cases, manufacturer's instructions should be consulted for installation procedures and details not covered by these listings.
Listed Materials are identified by a label or marking bearing the wording, "Listed Roofing Component", a reference number or code and the ETL Certification Mark.
