Contraflam fire resistant glass is temperature sensitive:
Contraflam EI30 fire resistant glass is used in DK88 Fireguard Window - Contraflam glass can be used in temperatures between -10oC...+45oC. On lower temperatures than -10C the glass freezes and becomes obscured. On higher than +45C the glass starts to react to high temperatures and turns white. This means that DK88 Fireguard window is neither suitable for rooms which are not heated during cold season nor the rooms where above normal temperatures could occur - i.e. saunas, boiler rooms etc.

3-glazed energy efficient window conforms to the fire resistance class EI30: it is resistant to fire for at least 30 minutes; it also serves as a heat insulator, so that the average temperature of the surface on the opposite side of the fire will not exceed 140°C. The fireguard window has been given the EI30 classification in accordance with the EN 16034:2014 standard (download certificate - pdf).
