Techni-Flo™ Engineered Ventilation System for steep-sloped roofs is the component system manufactured to ensure balanced airflow underneath the roof covering,
featuring polyiso foam insulation board specifically designed for sloped unventilated
roof decks. Techni-Flo™ RV, Atlas ACFoam® CrossVent®, and Techni-Flo™ EV make
up the only complete system in the industry manufactured to work together, delivering
ventilation capacity according to specification and optimizing roof temperature. The
Techni-Flo™ Engineered Ventilation System works with shingle or standing seam roofs.
Atlas ACFoam® CrossVent® combines polyiso insulation, a nailable surface and
ventilating airspace all in one panel. CrossVent® is polyiso insulation board with vent
spacer strips separating APA/TECO rated OSB from the polyiso insulation
Techni-Flo™ RV is an all-metal ridge vent featuring a snap on cover. It’s engineered
to job ventilation specs.
Techni-Flo™ EV is the engineered eave vent, allowing airflow through the
CrossVent® panel to the eave, creating prescribed ventilation capacity for each job.
