Technical Bulletin 1005: Silicone Butt Joints
Australian Glass Group
Under the right circumstances, a silicone butt joint can be considered as a full edge support. These circumstances are for an included angle of 90° to 160° however the silicone joint and glass must be designed appropriately. First we will consider single glazing, then the more complex double glazing. Silicone itself has some minimum requirements as per Dow Corning’s Manual; a minimum glueline and bite of 6mm, and a joint aspect ratio of between 1:1 to 3:1 in cross section. These silicone requirements may determine the glass thickness. Also, the gap between glass panes for glass thicker than 12mm must be a minimum of half that thickness.
