As the top thickness of the glass cools it contracts and forces the corresponding glass elements to contract to introduce stresses into the glass panel and increasing strength.

Before the float process, mirrors were plate glass as sheet glass had visual distortions that were akin to those seen in amusement park or funfair mirrors. Broadly speaking, different kinds of architectural glass can be used in different buildings based on the functionality required. Processed glass is a type of glass made by subjecting annealed or float glass to thermal or chemical treatment in order to change its properties. Laminated glass has similar properties to ballistic glass, but the two should not be confused. Float glass replaced this process. Today, there are various decorative glass types offer a variety of design options for residential or commercial solutions. Yet, low-E soft coated glass such AIS Ecosense provide optimum light transmission, thus being preferred in green glass architecture. The glass is chemically strengthened by submerging the glass in a bath containing a potassium salt (typically potassium nitrate) at 450 °C (842 °F). Architectural glass includes special types of glass used for building design and construction applications such as windows and doors. A nanometre-scale coating of titanium dioxide on the outer surface of glass introduces two mechanisms which lead to the self-cleaning property. The treatment on a mirror is used to obtain a soft matted reflection. If we stick to the definition of glass, then scientifically, it is defined as a non-crystalline amorphous solid that has the property of transparency, and is used for practical, technological and decorative purposes. It has a larger break pattern than tempered, but because it holds its shape (unlike the "wet blanket" effect of tempered laminated glass) it remains in the opening and can withstand more force for a longer period of time, making it much more difficult to get through. Heatable glass can be used in all kinds of standard glazing systems, made of wood, plastic, aluminum or steel. Glass coated with a low-emissivity substance can reflect radiant infrared energy, encouraging radiant heat to remain on the same side of the glass from which it originated, while letting visible light pass. Annealed glass is glass without internal stresses caused by heat treatment, i.e., rapid cooling, or by toughening or heat strengthening. While in the former, glass manifests itself as windshield and other components of automobiles and vehicles, in the latter, glass is used in doors, windows and other interior and exterior design and construction of buildings.

For this reason, automotive laminated glass is used in windshields. We will briefly feature some of the most common

Annealed Glass The spacers are small enough that they are visible only at very close distances, typically up to 1 m. However, the fact that the spacers will conduct some heat often leads in cold weather to the formation of temporary, grid-shaped patterns on the surface of an evacuated window, consisting either of small circles of interior condensation centred around the spacers, where the glass is slightly colder than average, or, when there is dew outside, small circles on the exterior face of the glass, in which the dew is absent because the spacers make the glass near them slightly warmer. In today’s world, modern glass variants are produced from float glass. The pattern is impressed upon the sheet by a printing roller which is brought down upon the glass as it leaves the main rolls while still soft. Laminated glass is a type of glass which consists of two sheets of glass with a plastic interlayer separating them. This glass is dimensionally inaccurate and often created visual distortions. This type of hard coated glass, such as the AIS Opal, is used in the exterior of buildings for providing optimum solar control.
