25 Nov.,2022

There is a lot more work involved in making residential and industrial windows than most people realise. When you scratch the surface, you will find a vast array of different window types and fabrication methods, and raise debates such as which is best in the debate between float glass and tempered glass?


Float glass is used for smaller windows in domestic homes, while larger windows are made from tempered glass. Glass is used for both aesthetic and functional purposes in windows, allowing the occupants to see out while allowing light in.

With all the different types of glass on the market, there are significant differences in quality and performance. Window systems that look the same are unlikely to perform the same, and there are some startling differences in quality and construction.


Whether a window performs well or not, it all starts with the type of window and what it is designed for. Next the glass products supplier will analyse the difference between float glass and tempered glass.


What is float glass?

Float glass is a very interesting and common type of glass, made using an incredible technology that produces very flat and attractive panes of glass. This involves a form of controlled cooling in which the glass is manufactured in such a way that it is subjected to minimal stress.

The main characteristics of float glass are

High translucency

Capable of being produced in a wide range of colours

Capable of being produced in a wide range of opacities

Good chemical inertness

Corroded by hydrofluoric acid (HF).


Float glass has a variety of applications in modern architecture, including commercial buildings and domestic buildings. However, with more advances in float glass manufacturing (e.g. ultra-thin float glass), new applications are being found in electronics and technology, such as television, computer and telephone screens. In addition, further advances in float glass production may lead to more sustainable or environmentally friendly buildings.


What is tempered glass?

Tempered glass is a stronger form of safety glass that usually shatters into small pieces when broken. The broken particles are small and relatively harmless compared to the sharp fragments produced by annealed glass breaking. The toughening process also greatly reduces the risk of thermal fracture and increases strength.


The most popular type of glass can be toughened glass, which is available in clear, tinted, reflective and low-e glass types.

Tempered glass is stronger than annealed glass

All forms of glass, including high performance glass, can be toughened


Tempered Glass

Tempered glass, on the other hand, is best suited for interior safety glazing applications. Homeowners can therefore use it for various door and window systems, such as shower doors and bath doors. It can also be used in hotel buildings consisting of conference rooms.


Tempered glass is also suitable for skyscrapers and commercial buildings with large windows. This way, the view outside is not distorted and the building's occupants are protected from elements such as storms.
