Silvano is the result of several years of implementation that have now led to a more versatile version (adaptable to an ever increasing type of window sills). At the same time, industrial processes have gradually been improved by looking for solutions that make it more durable but at the same time resistant (we have increased the thickness of the steel rod by 40%). The addition of galvanizing also to the support plate now makes it even more efficient, the reduced welding points in favor of mechanical couplings make it even less attackable by rust. The coupling system uses almost 40 cm in length of the sill making it so durable and safe over time, tests carried out show that the coupling system holds over 80 kg (176 lb).
