Tempered glass panels are easy to install and are stronger than normal glass, able to withstand temperatures up to 295 Celsius. There are two types of tempered glass: heat treated and chemically treated. Heat treated glass is strengthened through a process of rapid cooling after heating to 680 degrees, while chemically treated glass is heated and dissolved in potassium salts at 380 degrees. Tempered glass has many uses including as soundproof panels, in fire stations, for solar panels, and wherever non-fragile glass is required for safety. It can last a lifetime with proper care and investment in higher quality brands is recommended given its long-term value.
