Double Layer Fire Resistant Glass

Double Layer Fire Resistant Glass is made of two or more layers of glass original film, surrounded by glass strips and other intermediate strips, and is filled with water-soluble fireproof glue. After curing, it is a transparent jelly and glass. Special glass that is bonded into one and meets the corresponding fire rating. It can meet the requirements of fire-resistant integrity and fire-resistance and heat insulation at the same time.


Principle of fire protection

After the high temperature, the fire side is broken, and the special transparent chemical in the middle of the glass absorbs the heat generated in the flame to foam, expand and indurate, forming an opaque fireproof heat insulation board, which can effectively block the flame, smoke and high temperature poison gas spread, and prevent the high temperature from being transmitted from the fire to the back surface to cool down. It has gained some time for people in the backfire area to escape and rescue. This kind of fireproof glass not only has integrity of fire-resistant, and insulation of fire-resistant, but also has excellent sound insulation effect and belongs to Class A(EI Class) fireproof glass.

Professional design is very important:

Fireproof glass must be combined with the mounting frame and seals to form a complete fire protection system. If the frame is not a fireproof frame, when the fire occurs, the frame will soften, deform, and destroy the support function, and even the best fireproof glass can not play its due role. Therefore, the corresponding mounting frame and fire seal are also very important.


Product structure and instructions for use:

A glass-enclosed frame is visible around the glass for perimeter bead mounting. Ordinary grouting composite fireproof glass should not be used directly on the external wall. When used for the outer windows, consult the manufacturer ask for reasonable advice.
