Fireproof Glass

Fire-resistant glazing can withstand temperatures of 1000°C for a predetermined period of time to ensure sufficient escape time in case of fire.

These glazing units are of various types, such as single glazing units with reinforcement, monolithic, laminated glazing units with a thermally-activated expanding material in between.

Depending on their behaviour and performance, they are divided into the following types in order to meet the fire safety requirements of all categories:

Insulation (Insulation, class I) : Glazing of this class prevents the temperature from rising above 140°C on average on the insulated side and in no case should the temperature exceed 180°C at any point for a predetermined period of time.

Radiation (Radiation, class W): glazing of this class reduces the possibility of fire transmission as a result of radiant heat, either through the glazing itself or from its unexposed surface to adjacent objects on the insured side.

Integrity (Integrity, class E) : Glazing units must remain impervious to flames, smoke and fumes. No flame shall be permitted on the insured side for a specified preselected time.

Composite properties: such as glass panes with integrity against flame and reduced radiation permeability (class EW) and corresponding glass panes with integrity against flame and good insulation (class EI).
