Designed to specifically vent bathroom exhaust to the exterior, Soffit Flow expels hot, humid airflow in an outwards direction, beyond the fascia. Warm air naturally rises and Soffit Flow channels it away from the home, reducing the danger of mold and moisture buildup in the attic space - the leading cause of wood rot and structural damage. Constructed in the USA, this patented innovation is engineered from injection-molded high-density polyethylene (HDPE), a tough weather-resistant material valued for its thermal stability, UV protection and low moisture absorption properties. Soffit Flow is the perfect soffit vent for humid or coastal areas to aid in safeguarding the home against soffit moisture-related damage. Soffit Flow's high-density polyethylene (HDPE) material is durable, standing up to prolonged exposure to sunlight without becoming brittle. This UV resistance ensures that the material retains its strength and appearance over time, making it an ideal choice for both residential and commercial applications. Its finish is easy to clean and is unaffected by most industrial chemicals, strong oxidants, acid, alkaline salts and organic solvents. Soffit Flow is compatible with standard 4 in. ducting, making it a versatile solution for both new construction and retrofit projects. With a low-profile design and clean lines, it maintains the home's exterior aesthetics. Additionally, SoffitFlow's packaging doubles as an installation template.
