What is a Smartvent?
SmartVent is a tapered, under shingle plastic product designed for installation along the soffit edge of the roof or the facing edge of dormer rakes and goes virtually unnoticed. It allows air to flow freely through the 1" roof decking slit providing more than adequate soffit ventilation to maximize ridge vent effectiveness. This is extremely important since most ridge vent products require an equal amount of ventilation at the soffit in order to work properly. SmartVent, when used at both soffits, has a total NFA rating of 18 sq. in. (or 9 sq. in. on each side of a standard gable roof).
SmartVent is a patented roof and attic ventilation product that provides the best passive attic ventilation available. Using a unique design and installation method, SmartVent eliminates the problems and inefficiencies found in roof construction using ridge and soffit venting, namely inadequate vent openings in the soffit.
Are your ridge and soffit vents good enough?
Most houses with ridge vents do not have the proper soffit ventilation required because attic insulation blocks the soffit vents. SmartVent allows cooler air to enter under the shingle, through the 1" roof slit and out the ridge vent providing superior air flow and attic cooling.
