Hollow fireproof glass: double layer fireproof glass (two layers of single cesium potassium fireproof glass or other types of fireproof glass) can be selected. One layer can also be fireproof glass and the other layer is l0w-e glass coated with low radiation film. L0w-e film can customize glass with different radiation protection coefficients according to different radiation protection requirements of buildings.

Laminated fireproof glass: laminated fireproof glass, also known as laminated fireproof glass, is a kind of safety glass obtained after cooling at high temperature and high pressure by adding one or more layers of polyvinyl butyral (commonly known as PVB, SGP, EVA) with good toughness in the middle of two or more layers of monolithic fireproof glass.

Advantages and disadvantages of hollow fireproof glass and laminated fireproof glass:

1. Processing technology comparison.

Two or more pieces of hollow fireproof glass shall be placed evenly, and the surrounding shall be bonded and sealed with glue, and then filled with dry or special gas. Generally, the hollow fireproof glass is a double-layer structure. The glass substrate can select transparent glass, heat reflective glass, tempered glass, etc., with good thermal insulation.

The original glass sheet selected for laminated fireproof glass, and the number of interlayer is the same as that of hollow fireproof glass, which can be selected according to the actual situation. The difference is that the middle of the laminated fireproof glass is made of PVB resin film pressed at high temperature. The laminated glass can be made of 2 / 3 / 5 / 7 layers, most of which can reach 9 layers.

2. Comparison of product characteristics.

The optical function and transmittance of the two are similar; The thermal insulation function of hollow fireproof glass is better than that of interlayer; Hollow fireproof glass has the characteristics of anti condensation; Laminated fireproof glass can reduce UV penetration and protect indoor facilities; The safety function of laminated fireproof glass bonded with PVB film is better than that of hollow glass. Even if the glass is broken, the fragments will not fall and hurt people.

Because if the processing technology of laminated fireproof glass products is not hard, it simply forms the situation of film bubbles and edge falling in the later stage. Therefore, the application range of hollow fireproof glass is relatively wide, and it is widely used in fireproof windows and fireproof glass doors.

3. Use range comparison.

Hollow fireproof glass is mainly used in hotels, shopping malls, hospitals, office buildings and other places with high requirements for thermal insulation, heat insulation and sound insulation. It is also used in ships and vehicles.

Laminated fireproof glass is mainly used for skylights, stair breast boards, doors and windows in buildings, and places with high safety requirements such as banks, finance, shops, windows, partitions, underwater works and so on.
