The owners’ desire to eliminate deck fasteners lead to the selection of the V²T roofing system. V²T 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. Destructive uplift pressures are counteracted by a greater vacuum force created by the vent. http://www.v2troofsystem.com/
