The invisible and safe glazing bead
In today’s modern windows, glass panes have become much larger and heavier than in the past. Nevertheless, the fixing system of glazing beads has remained unchanged over the years.
In the past plain small nails were used to fix the glazing bead, which became rusty and damaged the paint layer. Today, headless spike nails are used, with a lower aesthetic impact. And still, they do not guarantee an acceptable security level against burglary and wind. Moreover, the continuous stress on the glass pane may have it fall down on the interior side of the room, and this would be an hazardous occurrence.
In order to increase security, manufacturer have often recourse to anti-burglary hardware, which is useless if the glass pane is not fixed with a safer method. To this aim, small nails and headless spike nails can be replaced by iron screws, which – on the other hand – have a negative aesthetic impact on the window.
INVISIBLE TACK has been conceived, a bush composed of a special plastic material which enables the glass pane to be safely fixed, with no visible detail on the glazing bead lath.
The operation is made with a special drilling machine, which drills a hole in the inner side of the glazing bead, where an “invisible” bead is inserted, and then it will be screwed against the glass pane, so that it is safely blocked.
The final result is an extremely safe locking of the glass pane, making it impossible to push it out of its location.
Not only does this solution offer advantages in terms of robustness, security and aesthetics. There are practical advantages too. For instance, when replacing the glass pane, all you have to do is extract the glazing bead lath, remove the screw and insert a new glass pane.
