AIS Pyrobel: Heat Resistant Glass and Types of Fire Resistant Glasses


AIS Pyrobel is a laminated glass with an intumescent layer. A high-end Fire-Resistant Glass range, AIS Pyrobel is specially engineered to withstand extreme levels of heat, restrict heat transfer and prevent the passage of smoke and flames.

These are tempered and laminated glasses. They prevent the flames and also control the radiation on the non-fire side to a maximum of 15KW per sqm. They offer integrity and provide for low heat radiation. They are used for internal and external applications.
These types of glasses offer integrity and insulation. The maximum temperature on the non-fire side does not exceed an average of 140 degree Celsius.

How it works

AIS Pyrobel is a multi-laminated glass assembled with clear intumescent interlayers. In case of fire, these interlayers expand at around 120°C and transform into a rigid and opaque shield.


Pyrobel is a proven and tested world-class product from our partner AGC. With huge strides being made in design and safety standards of buildings in India, the need for quality fire-resistant glass products has become critical. This is why Pyrobel is now brought to you by AIS.
