Recovery over an existing ballasted EPDM. Ballast was removed EPDM left in place as a vapor barrier and an air containment layer. A 2”poly-isocyanurate insulation board was mechanically attached to the metal deck to secure the assembly. Installation completed in September 2009.
V²T Vent uses the power of the wind to hold the roof securely in place. The technology behind the vent is based on a recognized physics principal to create a vacuum that becomes stronger as the speed of wind increases. The vacuum pulls the air from under the membrane – drawing it down to the deck and holding the membrane firmly in place. The reality is, destructive uplift pressures are counteracted by a greater vacuum force created by the vent.
The harder the wind blows the better the vent works.
The V2T Roof System is different from existing roof vent devices because it uses the Venturi principle to capture the dynamic flow of air across the roof’s surface to generate low pressure. The vent works with the effects of the wind instead of against it. Other significant features of the V2T Technology include:
Developed in conjunction with Boeing under a prestigious award from the Space Alliance Technology Outreach Program (SATOP), the V2T Roof System utilizes a space sensor technology to monitor and measure:
By leveraging this technology, the V2T Roof System tells you both when AND where you have a potential leak or other compromise in your roof. Having this information not only extends the life of your roof, but also lowers the cost of maintenance and ownership.
A sensor located inside the upper hemisphere of the vent transmits readings wirelessly to the data acquisition hub housed inside the building. Data is then transmitted from the hub over the internet to Virginia Tech for analysis. V2T can provide roof owners, consultants, or your contractor with relevant moisture and pressure reports, keeping your roof in the best shape possible. The system is powered by solar cells with battery backup located on the V2T Vent.
