For example, single layer and laminated toughened/tempered glass panels can be installed with countersunk fittings, clamping plates and bonded fittings. As a result, these special attachments ensure the Manfred Frank range is ideal as glass door hinges. Most importantly, toughened/tempered glass is up to five times stronger than float/ annealed glass of the same thickness. Furthermore; this type of glass can also be laminated, where two sheets are bonded by a plastic or resin inter-layer.
Countersunk fittings and clamping plates cannot be used on laminated float or annealed glass. Therefore, the only way to install laminated float glass is by bonding the glass panel to a special attachment plate first (See Door Mounting Options). Likewise, another mounting option is to bond the panel into a channel extrusion or profile and attach the relevant mechanism to the metal profile.
