Breathable Sealant Flex-O-Vent is a flexible ventilated sealing strip designed for ridge, hip, and roof transition applications in metal roofing systems. It combines reliable weather protection with continuous roof ventilation to help maintain balanced attic airflow and moisture control.
The breathable foam structure allows warm and humid air to escape from the roof cavity while preventing wind-driven rain, snow, dust, insects, and debris from entering the ventilation space. Its flexible design adapts to different roof profiles and provides a secure fit along uneven surfaces.
Breathable Sealant Flex-O-Vent is commonly installed beneath ridge caps and roof transitions where controlled ventilation and weather sealing are required. The durable weather-resistant material maintains long-term flexibility and performance under changing climate conditions.
Compatible with metal tile roofing, standing seam systems, and other ventilated roofing applications.
