When considering the use of fire resistant glass, it is important to know the difference between Grade A and Grade B products. The difference between the two grades is not always obvious. In some cases, this will depend on the building's fire safety standards.
Fire resistant glass is usually divided into laminated glass, thin coated glass, monolithic glass or line shielded glass. Each type of fireproof glass has distinct characteristics. Grades of fire resistant glass vary in terms of heat insulation, smoke insulation and fire resistance limits.
Class A fire resistant glass is made of tempered glass with a fire-resistant gel sandwich. The glass also has spacers mounted on the perimeter edges and edge seals to prevent gel leakage. The thickness of the gel is usually greater than 3 mm and can range from 18 to 55 mm. However, only one type of fire-resistant glass is suitable for every application, and this is called UV stabilized glass.
Fire resistant glass is a popular material used in the home and construction industries. It can be used for building Windows, partition walls, skylights, smoke walls, perspective floors, outdoor Windows, etc. Because it is relatively new, not many glass makers are familiar with its features and benefits. This can lead to confusion between specifiers and incorrect applications.
Fire resistant glass has high thermal shock resistance, making it durable. It also has good thermostatic storage stability. In addition, it can withstand temperature variations from -20°C to 80°C. Its high battery life is another advantage.
Fire resistant glass can also be classified as borosilicate glass. This type of glass contains 15% boron trioxide, which alters the behavior of the material. Due to its low coefficient of thermal expansion, borosilicate glass is resistant to heat impact and will not crack under extreme thermal changes. Often used in high-end restaurants, wineries, laboratories, etc. However, it is important to remember that not all borosilicate glasses are created equal.
