How the windows and doors manufacture select the glass?

As the part of windows and doors, the glass plays an important roles on the sound insulation, thermal insulation and the wind pressure resistance. How to choose the suitable glass for the high-end windows and doors?

1 Security-tempered glass.
As the safety glass, the strength for tempered glass is 4~5 times higher than normal annealed glass, its bending resistance strength is 3~5 times higher than normal float glass, and the impacting resistance is 5~10 times higher than non-tempered glass. After tempered, the thermal shock is also been double or triple improved, it can resist the temperature changes more than 150℃, have good performance on the thermal explosion.

2 Sound-proof and thermal proof-insulated glass.

The insulated glass is made with two or more glass pieces, the edges is sealed by compound binder with high strength and high air tightness. The glass will be stuck with the hollow aluminum spacer which have desiccant in it, then fill with argon, to produce the insulated glass with good performance on sound insulation and thermal insulation.

3 Shock-proof and explosion-proof-laminated glass.

Laminated glass is produced with two glass pieces or more pieces with interlayer of polymer film, under high pressure and high temperature treatment, the glass and interlayer film with stick together permanently. So even the laminated glass broken, the glass will stick on the film without dropping, to protect the human against any injury. The object and people couldn’t penetrate the laminated glass easily, stop any objects falling from high buildings.

4 Heat insulation and light transmission-Low e glass

Low e glass is also called low emissivity glass, it is made through the coating process with one or more layers of metallic oxides and other compounds. The coating layer could lower the glass emissivity. For normal float glass, the emissivity is around 0.84, but for low e glass, it is around 0.15. This could ensure the light requirement, also keep the comfortable indoor temperature.

There are three normal type for the low e glass, first is the low e with high transmitance, which could let massive sunlight radiate into the indoor, but also reflect the ultrared rays. Second is the  sunshade low e glass. It could shade the light from solar radiation, without affecting the transmission of visible light. Third is low e glass with double silver layer. The total film layer is more than 9 layers, it is featured by high transmitance and good sunshade effect.

5 Beauty and safety -Wired glass

The wired glass is also called shatterproof glass and glass with metal wire. It have good performance on the fire-proof, could resist the fire and won’t explode in the high temperature. At the same time, it could be penetrated easily. Even broken, the fragments won’t fly apart, is one kind of safety glass. The wired glass could also improve the decorative effect greatly.

6 Intelligent and energy-saving-switchable glass

The switchable glass is also called privacy glass, smart glass ,PDLC glass and magic glass. It is produced by fixing the PDLC film between glass pieces, under other special treatment, the glass will like the laminated glass. It is featured by clear with power on, obscure with power off. The smart glass can protect the privacy perfectly, and have good performance on energy-saving.
