Southern Diversified Industries

Southern Diversified Industries, located in Baldwyn, Mississippi, was created in 1984 as one of the manufacturing divisions of Diversi-Plast Products.  

Southern Diversified Industries manufactures Trimline Ridge Vent.  The Trimline Ridge Vent draws fresh air from soffit vents and continually releases hot, moist air through the ridgeline. This air movement creates a balanced ventilation system which maximizes ventilation efficiency and minimizes potential damage caused by trapped hot air. For further protection, Trimline's exclusive StormStop membrane, made of revolutionary spun-bound material, releases hot air while simultaneously keeping damaging moisture from entering the attic space.
