Hollow fireproof glass and composite fireproof glass are manufactured by processing two or more layers of fireproof glass. The interior of hollow fireproof glass is filled with monotonic gas, and the frame is filled with single agent. The interior of the composite fireproof glass is filled with high transparent fireproof liquid to achieve the function of fire prevention.

Although hollow and composite fireproof glass look similar, they are very different in application.

1. The weather resistance is different.

The monotonic agent filled inside the hollow fire-proof glass will not produce physical or chemical changes under long-term sun irradiation, which can keep the glass clean and bright for a long time. Hollow fire-proof glass is required to be free of stains and adhesives that prevent vision when leaving the factory. The interior of the composite fireproof glass is filled with fireproof liquid, which is prone to physical reaction under the solar radiation, and will bubble and yellowing overnight, affecting the beauty of the glass.

2. Different fire resistance time

The hollow fireproof glass can be superimposed by multiple single pieces of fireproof glass, so the fire resistance function is also good. Under the impact of high-intensity flame, it can not crack for 90 ~ 180 minutes. In general, the composite fire-proof glass can withstand fire for 90 minutes. Adjust the thickness to achieve different fire-proof time.

3. Different thermal insulation

Both sides of hollow fireproof glass are single fireproof glass or other glass, which does not have thermal insulation integrity. When the composite fire-proof glass encounters an open fire, the glass on the fire facing surface cracks, and the fire-proof liquid and high temperature swell immediately to form a white firewall, which can effectively isolate the heat caused by flame burning from transmitting to the back fire surface, so as to avoid the damage of personnel or articles on the back fire surface by high temperature and high radiation.

4. Different functions

The middle of the hollow fireproof glass is filled with monotonic gas, which is a medium without reflecting radiation. The fire-proof liquid of composite fire-proof glass forms a firewall when it meets heat, which can resist the high-temperature radiation of flame and the extension of toxic gas.

5. Different application directions

Hollow fireproof glass is suitable for office buildings, hospitals, fireproof glass partitions, fireproof doors, fireproof windows, etc; Composite fireproof glass is suitable for fireproof glass windows, fire barriers, fire doors, etc. in shopping malls, computer rooms, archives, etc.
