Limits the spread of fire and smoke
Fire-resistant glass can be divided into three classes by their fire-protection grade. In the event of a fire it limits the spread of fire and smoke; the highest grade glass also provides thermal insulation.
It should be noted that this fire-resistant glass is not suitable for oven and stove doors, and places that are constantly exposed to fire.
E class ensures the integrity of the glass which provides partial protection. In the case of fire, spreading of flame or hot gases is delayed for a certain period of time. A disadvantage of this type of glass is its intensive heat emission.
Available classes include E30, E60, E90 and even E120 glass.
By its characteristics (protection level, thickness, weight) this class is between E and EI class glass. Protection provided by EW class glass is lower than EI class protection but higher than E class. The glass has a one-piece structure and limited thermal insulation. Available classes include EW30 and EW60.
EI class ensures the integrity of the glass and its thermal insulation, as well as full protection in the case of fire. The glass is thick and heavy. In the case of fire, spreading of flame and hot gases is delayed for a longer period of time.
The EI class fire-resistant glass is laminated from two or more glass panels between which there is a special transparent gel, which in the case of fire becomes non-transparent and creates a strong, light and flame proof shield.
Available classes include EI30, EI60, EI90 and EI120 glass.
