What do you know about sandwiched laminated glass?
Firstly, we need to understand what is sandwiched laminated glass. Normally it consists of two or more pieces of glass sandwiched and between one or more layers of organic polymer interlayer film. Then after special high-temperature pre-pressing (or vacuum) and high-pressure process. The glass and interlayer film are permanently bonding together. Its characteristics are transparency, explosion protection, waterproof and UV protection. Thus the sandwiched laminated glass panel is suitable for architectural decoration, outdoor decoration, home decoration, etc.
The most common interlayer films are: PVB, SGP, EVA, PU etc.
In addition, there are some special ones such as color interlayer film, SGX type printing interlayer film, XIR type LOW-E interlayer film etc. The normal options of decorative and functional embed parts are fabric, metal mesh, metal plate, etc. It also customizable by designer’s idea.
- Depends on the melting point of the interlayer film, it divide into low temperature laminated glass, high temperature laminated glassand insulated glass;
- According to the different materials in the middle-layer, it divide into paper, fabric, clip plant, wire, mesh etc;
- About the bonding method between the interlayers, it divide into mixable laminated glass, dry laminated glass, insulatedlaminated glass;
- According to the different layers of the glue, it divide into general laminating glass and bulletproof glass.
Most architectural glass uses sandwiched laminated glass door and wall. It not only to avoid injury accidents, but also because it has excellent seismic intrusion capability. The intermediate film can resist the continuous attack of weapons. Such as hammers, hatchets, and can resist bullet penetration for a long time. Its safety precautions are extremely high. The glass is safely broken and may break under heavy ball impact. But the entire glass remains in a one-piece interlayer, and the fragments and sharp small pieces remain stuck to the interlayer film.
