The term "float" glass is derived from the production method, which was introduced in UK by Sir Alastair Pilkington in the late 1950's.Today 90% of flat glass is manufactured all over the world.

It is a sheet of glass made by floating molten glass on a bed of molten tin. This method gives a uniform thickness and very flat surfaces to the sheet. The main components of Soda Lime glass, Silica sand (73%), Calcium oxide (9%), Soda (13%) and Magnesium (4%), are weighed and mixed into separate batches to which the recycled glass (cullet) is added. The use of ‘cullet’ reduces the consumption of natural gas. The entire production process from the batching of raw materials to cutting and stocking is fully automatic and computer-controlled.

Tempered Glass is also known as ‘Toughened Glass’. Tempered glass is made by various processes which create balanced internal stresses giving the glass extra strength. In the process of making tempered glass, it is placed onto a roller table, taking it through a furnace which heats it above its annealing point of about 720 °C. The glass is then rapidly cooled with forced air draft process, while the inner portion remains free to flow for a short span of time. It has thermal resistance, which breaks it into small cuboids fragments rather than shards and is less likely to cause injury. Thus for the purpose of the safety, tempered glass is used in a variety of demanding applications, such as vehicle windows, glass doors and tables. Also work as a component of bulletproof glass for diving masks. Manufacturing industries use tempered glass in refrigerators, furniture, ovens, shelving, and fireplace screens.

Heat-strengthened glass treated with heat to induce surface compression, not to the extent of causing it to "dice" on breaking in the manner of tempered glass. On breaking, heat-strengthened glass breaks into various sharp pieces that are typically smaller than those found on breaking annealed glass, and act as an intermediate in strengthening between annealed and toughened glasses. Heat strengthened glass is supplied to the manufacturer with a permanent mark in one corner for identifying, such as SAFEX and the words Heat Strengthened .Heat-Strengthened glass is NOT a safety glazing product, therefore should not be used where safety glazing is required. Heat-strengthened products from SIGTuff are apt for commercial use including spandrels, windows in high wind load areas, and applications where the glass is expected to develop high thermal stresses.

Solar Control Glass is one which has been treated during the manufacturing or using a coating to restrict the amount of sun-generated infrared or ultraviolet radiation passing through the glass. In the process of making Solar Control Glass Metallic oxides are applied at high temperatures onto clear or body tinted glass, and fused by Pyrolysis into the surface of the glass. This process creates a Highly Scratch Resistant and stable coating. These coatings take various forms. Such as, Hard Coating and Soft Coating. Solar control glass can be in any situation where excessive solar heat is likely to be gained. For example: Large Façades, Glass Walkways, Atria and Conservatories.

Multiple “ glass panes ” are assembled into units, commonly referred to as "insulated glass" or "Double glazing Units" or Insulating Glass Units (IGU). The technical term for the assembly is Hermetically Sealed Units. It means that the environment present inside of the unit is isolated from the external environment. These units are produced with the intention of maximizing the thermal properties of gas which is contained in the space formed by the unit while at the same time providing clear vision through the unit at low temperatures. Mostly, all insulated glasses are double glazed. But, these days, the glasses with three sheets also called as “triple glazing “are becoming more common due to its higher energy costs. Insulated glazing can be constrained into a sash, frame or a curtain wall. Insulated glasses lasts from 10 to 25 years, with windows facing south (Northern Hemisphere) and the north (Southern Hemisphere) hardly lasts more than 12 years.
