Tempered insulated glass is a type of glass that undergoes a thermal treatment process, known as tempering, which increases its strength and enhances its safety. This process involves heating the glass to extremely high temperatures and then rapidly cooling it. As a result, tempered glass is significantly more resistant to impact and thermal stresses than untreated glass.

Glass is probably the most overlooked material in history. It is essential to our lives, even more important than plastic. To me, a world without glass is even harder to imagine than a terraforming Mars (which most scientists agree is practically impossible). Without this miracle all around us, you wouldn't be able to use a touch-screen phone, turn on a glass light, see from a window, wear glasses, or enjoy a drink from a glass bottle on your bedside table. You won't be able to receive email, phone calls or access the Internet.
