Today, fire-resistant glass is expected to have more performance properties, which are reached through adding some functional glass panels to the single unit. POLFLAM^® fire-resistant glass has been based on the Guardian^® glass, just like POLFLAM extra units with functional layers. POLFLAM uses a calculation program called Guardian® Configurator, which enables calculation of parameters for glassed partitions in various configurations for all EI classes. Guardian^® Configurator is an application to calculate spectrophotometric and thermal properties of the selected configurations of glazed walls. The software will also specify the parameters of a glass panel mounted in facades of various tilt angles. The calculated figures have been collected in the detailed pdf report which contains table-listed performance properties in compliance with the standards EN 410 and EN 673.
