The V²T is designed to hold down a membrane securely to the roof structure during high wind events. Using the laws of physics, the higher the wind speed, the more force this technology has to secure your roof. This technology is ideal for low sloped roofs in environments with high winds, like south Florida, and on buildings where fully adhering a membrane is not an option.

To guarantee that is this technology is effective, scale models were tested in Wind Tunnels at Virginia Tech. Once the promising technology was tested and proven on a small scale, a full scale roof mock up was made with this system and tested in the full scale wind tunnel at the NASA Langley Air Force Base.
The Langley Full Scale Tunnel was put into service by the National Advisory Committee for Aeronautics (NACA), NASA’s predecessor, in May 1931. At the time of its commissioning it was by far the largest wind tunnel ever built, and is still one of the four largest in the world. In its day, it was considered an extremely innovative design because of its double return configuration, and the location of its dual fans.
