Toughened Glass

Trent Glass toughened glass is up to five times stronger than ordinary glass of the same thickness. Because of this increased strength, Trent Glass toughened glass allows architects, designers and builders greater freedom in the use of glass in building design and interiors. Trent Glass Toughened Glass can offer a complete and proven solution. It exceeds worldwide safety standards for glass subjected to all levels of human impact. Toughened glass is now required by regulation for every building project due to its increased strength and safety characteristics.

Trent Glass Toughened Safety Glass is manufactured by subjecting final size and shaped panes of glass to a heating and cooling treatment whereby high compressive stresses are set up at the surfaces with balancing tensile stresses in the centre. The high compressive surface stresses gives Trent Glass toughened glass its increased strength to meet all demands.


Trent Glass use a horizontal bed toughening furnace to manufacture toughened glass to BS EN 12150 with a maximum size of 6000x3000mm in the following thicknesses 4,6,8,10,12,15 and 19mm

Heat Soaked Toughened glass

Trent Glass heat soaked toughened glass is available for those applications where a reduction in spontaneous fracture is advantageous, such as structural applications, barriers and roof glazing.

Heat soaking is a destructive process in which a pane of toughened glass is subjected to temperatures of 280° for several hours over a specific temperature gradient, to induce fracture. This test ensures that if there is probability of breakage, caused by naturally occurring elements of nickel sulphide (NiS) having been present when the glass was produced, then the infected panes break inside the furnace. Up to 95% of NiS infested panels are usually destroyed inside the heat soak chamber at the factory and hence reducing the chances of onsite breakages.

The heat soaking process is one method of reducing the incidence of NiS induced failure in toughened glass, by causing the phase change to occur before the glass is installed in the building. The heat soaking process is not 100% effective and failures have been known to occur in rare circumstances.
Based upon the European rate of Nickel Sulphide inclusion, there will be one critical inclusion in every 4 tons of glass, an understanding of the problem by manufacturers has caused them to take steps to eliminate this impurity.

Trent Glass heat soaked toughened glass is typically used for High Rise Curtain Walling, overhead glazing and canopies , balconies and balustrades. In fact ,any application where superior toughened glass is required.

Maximum size of 6000x3000mm in the following thicknesses 4,6,8,10,12,15 and 19mm are available.
