Curved glass refers to a type of special glass that's been specially shaped, using heat and a metal mold, to assume a curved form rather than the common flat plane. It's also called bent glass, and bears a striking appearance that makes it useful in many different industries.
Double-glazed units are often referred to as (DGU's) double-glazed units or (IGU's) insulated glass units.
Double Glazing consists of two pieces of glass with a spacer bar in between that creates an airspace, which is then sealed together producing a completely sealed insulated glass unit (IGU).
Laminated glass is constructed of two plies of glass which are bonded together with interlayers to form a permanent bond. The interlayers work to support and hold the glass to create a strong, uniform layer even when broken.
Toughened glass is a safety glass that has undergone processes of controlled thermal treatment to increase its strength. Also known as 'Tempered glass', toughened glass is made from annealed glass that has been heated to approximately 650â?°C and then rapidly cooled, making it four times stronger than ordinary glass.
Due to the increased heat treatment and rapid cooling of the glass, the treatment produces different physical properties. This results in compressive stress on the surface and improved bending strength of the glass. Before toughening, the glass must be cut to the correct size or pressed to shape.
The Process of Toughening
The glass is carried by rollers and goes through the furnace. Three types of modes are used to heat the glass - conduction, convection, and radiation. While the rollers help to conduct the heat, the coils enable radiation of heat. This ensures that the glass is evenly heated on every side. By blasting air on both the surfaces, the heated glass is then cooled uniformly.
