To ensure performance across varying applications, McElroy Metal's R-Panel has been thoroughly tested. R-panel wall and roof panels feature a Class A fire rating under UL 790 (ASTM E108 and NFPA 256) procedures. Other R-Panel testing and classifications includes UL 580 Class 90 Uplift testing, ASTM E1680 air infiltration, ASTM E1646 water infiltration, and UL2218 Class 4 impact resistance.
R-Panel also has Florida State Approval 1747.9 and 1832.11, Miami Dade Approval (PBR only) and Texas Department of Insurance Approval RC-284 (PBR only).
Installation of R-panel roofs requires a minimum slope of 1:12 and butyl sealant should be utilized in the laps.
