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 events.
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.
Since 2005, XVentBox has been specified across high-density projects throughout the U.S., Canada, and the Caribbean from affordable and student housing to senior living and world-class multi-family and mixed-use developments.
XVentBox incorporates a removable front louver and an integrated back draft damper/s for easy inspection and maintenance without damaging any weather-tight seals.
A 1 hour fire rated XVentBox option is available across all standard cavity box models, factory installed.
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 from accessing the duct, and reducing the potential for insect intrusion.
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.
XVentbox® systems are engineered for seamless integration into modern wall assemblies, replacing traditional wall caps with a more advanced exterior vent termination solution. Designed for residential applications including dryer, bathroom, kitchen hood exhaust, and fresh air intake.
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.
Designed with a focus on performance, efficient installation, and seamless aesthetic integration without unnecessary complexity. Project lists available upon request.
