What is 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 roof to wall 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. per foot(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, dormers, transition roofs, mansard roofs, chimneys and skylights.

SmartVent can be use at the eave, mid-roof, shed-wall, off-peak and dormers

What is a SmartVent Tapered End Cap?

SmartVent End Caps are 10.5″ square tapered ventilation pieces that seamlessly blend with Smartvent to give the roof a more aesthetic and clean finish to your intake ventilation project. (Do not use SmartVent End Caps at the rake edges)

The patented ‘Universal’ SmartVent End Cap can be installed Right Side or Left Side, as you begin your SmartVent run or end the run. Designed with the contractor in mind, this easy to install end cap makes working with SmartVent simple and cost effective. Use it to end a SmartVent run near a dormer, valley, hip, chimney or skylight. Use it to begin a SmartVent run other than at the rake edge. At the rake edge, wrap SmartVent fabric around a full piece of SmartVent as shown in the SmartVent directions.

The SmartVent End Cap ‘tapers’ the SmartVent back down to the roof. All that you need to do is nail it down to the roof. Period! The fabric is already attached at the factory for right hand or left hand installations.

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.
