JP H05-254770 A claim 1. - The known assembly methods of such panels envisage, after positioning of the glass portion, a step of soldering the profiles to each other and to the frame.
- The soldered profiles present problems related to the tolerance deriving from the placing of two elements to be soldered alongside each other as well as to the thermal deformation which produces tensions between the metal sheets forming the profiles.
