The VentSure® InFlow™ Vent is a 4-ft. strip, shingle-over intake vent designed for soffit-less, exposed-rafter homes or homes without adequate air intake. It installs easily without the need to disturb the soffit, gutter or fascia and its versatile, patent-pending design allows for roof deck installation at the eave or mid-roof. A unique bottom intake helps protect against wind-driven rain while providing an NFVA of 10 sq. in./LF. The VentSure® InFlow™ Vent also provides a low-profile, 3-plane contour for a smooth roofline transition and is designed to work as an integral part of a VentSure® Balanced Air Ventilation System. http://www.owenscorning.com/roofing/accessories/ventilation/inflow/
