V-Top Rooftop System –Windstream
The traditional flat roof bracket installation system adopts two ways: bottom connection and adding load.The former can damage the roof surface, while the latter requires certain roof loads.Valvald's self-developed Windstream applies hydrodynamics and USES the bottom widened aluminum rail and stainless steel coaming, without adding load and without any damage to the roof.Windstream has passed the Wind tunnel experiment at the Technical University of Munich.
