In our experience of more than 10 years in the world of glass curtains we have had the opportunity to know both options very well. After this time, we have come to the conclusion that, without a doubt, the weight supported above is much more suitable for glasses with heights between 1000 mm and 2700 mm. These, as they are hung with special bearings, make the handling of the panels much easier, more manageable and durable over time, offering us maximum impermeability, robustness and safety of the panels themselves. When they are hung, the lower profile is used as a guide, so it is not affected by dirt as when they are slid. We have experienced that systems supported in the bottom, after a few months and due to the inevitable dirt coming from the outside, are difficult to move and cause more wear, thus giving a shorter life to the system. Therefore, we understand, believe and advise you that if you want to put a glass curtain, it is best to choose a system with the weight up. It is very important and you should always take into account the quality of the system that you are going to choose, whether it is weight supported up or down.
