Why does the construction tremble under wind load?
Do you know that under strong wind loads any frameless system of a balcony type, no matter who is the manufacture, has the ability to tremble? Why? Because the roller groove in the molding is slightly larger than the roller size, as it is technically conceived for the correct operation of the system. After all, aluminum has the property of expanding and narrowing, respectively, the roller should have enough space for a smooth ride. The only significant difference between manufacturers may be outlined by trembling volume, which depends on the quality of roller wheels material. But why do we speak about this issue? We wanted to share a little secret how this problem was solved in Vizyon VBS sliding frameless systems of the balcony and terrace type. So, inside the molding there is a groove where the brush (felt) is inserted, it fills in the free space inside and the roller always remains in a strictly limited space when expanding or narrowing the molding.
