Fire-resistant glass provides increased fire safety. Standard float glass breaks very quickly in the event of a fire. During a fire, a temperature difference occurs between the glass surface and the glass edges. This results in stress within the pane. When this stress becomes too high, cracks appear. For float glass, this happens within approximately 1 minute during a fire. Fire-resistant glass is constructed in layers (laminated glass). Standard laminated glass remains fire-resistant for 4 to 5 minutes. With special fire-resistant glass, this ranges from 30 minutes up to 2 hours.
Types of fire-resistant glass
Fire-resistant glass is available in various classifications. The choice depends on, among other things, the type of building, its function, and the applicable fire safety regulations, requirements, and standards. For example, there are specific requirements regarding resistance to fire spread and fire penetration. The degree of fire resistance is expressed in minutes, such as 30-minute fire-resistant glass and 60-minute fire-resistant glass.
Glashandel Sloos always installs fire-resistant glass exactly as it was tested. The test report specifies exactly which frame and which materials were used during the test and, therefore, must be used in practice. Naturally, the glass meets the necessary requirements to be classified as fire-resistant.
