What is tempered or safety glass?
Tempered glass when broken, shatters into many small fragments, which prevent major injuries. Due to these characteristics tempered glass is used traditionally in applications requiring increased strength such as double glazed doors and double glazed windows, which reduces the likelihood of injury in the event of breakages. However tempered glass should receive the same care as annealed glass. Double Glazing Insulation. Turning to the double glazing window glass itself, the insulating effect of double glazing can be affected by a number of factors. Double glazing insulation is affected by cavity width, the use of argon instead of air in between the panes or by utilising a low emissivity coating that reflects heat back into the room. The latest double glazing offers greatly improved insulation compared to traditional single glazing openings. In addition to their better insulation, double glazing windows are also draught-proof. Double glazing therefore reduces the amount of heat or cold
