Vents. Reinvented.™
Applications.
Modular.
Designed with a modular approach, XVentBox products provide multiple orientations and duct port configurations for 4″, 6″, and 8″ connections. This system allows single, double, or triple duct connectivity within a single assembly, with customization available for specific field conditions.

Our Presence.
Every product we engineer is designed for long-term success.
Benefits.
XVentBox incorporates a removable front louver and an integrated back draft damper/s for easy inspection and maintenance without damaging any weather-tight seals.
NO WATER INTRUSION
The molding process creates a monolithic box cavity that combined with integrated balanced gravity dampers XVentBox provides a superior barrier against wind driven rain.
Our products successfully prevent water from breaching the exterior building envelope, even in extreme conditions like hurricanes or high wind event.
IMPROVED AIR QUALITY
Differences in air moisture content and/or temperatures between interior and exterior can create conditions in which mold thrives and the deterioration of construction materials accelerates.
ELIMINATE NOISE
When wind encounters the basic vent cap it rattles the damper (if there is any), or even rips it off. People in beach/lakefront residences often find themselves kept up at night by wind.
Our unique design makes use of windy conditions to make the damper close more securely, eliminating wind generated noises.
PREVENTS NESTING
The front louver allows for proper air flow but prevents birds or other creatures from taking residence. Dealing with animal feces, and noise associated with nest-building, are not pleasant either.
Our design makes it “Critter Proof” preventing birds or squirrels to access the duct, and insect access unlikely.
Fire Rated.
Projects.
Seamless integration across a multitude of exterior assemblies enhancing the architecture. XventBox is designed to disappear.
