These flashings are compounded specifically for maximum resistance weathering due to ozone and ultraviolet light. A C-12 ASTM additional requirement was added to assure conformance to the most stringent ozone/weathering specifications available
The base of the flashing is designed to form a seal on most panel configurations and roof pitch regardless of pipe location. The pitch canal allows for maximum flexibility, accommodating up to a 60 degree pitch without affecting performance.
