Laminated glass and low-emissive glass which earlier?
It seems to be laminated glass (do not know right ..)
Laminated glass appeared early But this is two sorting methods.
Laminated glass 70 years have been.
Low-E glass is another new type of energy-saving glass that has emerged since the 1990s. It uses high-tech coating technology, the glass surface coated with a special metal compound film, can reflect the infrared, far infrared radiation, blocking the heat transfer. At the same time, low-radiation glass still maintain a good light transmission, in blocking the heat transfer at the same time, does not affect the indoor light.
Laminated glass is made of two or more pieces of glass, sandwiched between one or more layers of organic polymer interlayer, after special high temperature preload (or vacuum) and high temperature and high pressure process, the glass and the middle film permanent Bonding as one of the composite glass products.
Commonly used laminated glass interlayer: PVB, SGP, EVA, PU and so on.
In addition, there are some more special, such as color interlayer laminated glass, SGX printing interlayer laminated glass, XIR class LOW-E interlayer laminated glass. Embedded decorative pieces (metal mesh, metal plate, etc.) laminated glass, embedded PET material laminated glass and other decorative and functional laminated glass.
Low-E glass is also known as Low-E glass, Low-E is English short-Emissivity short. Low-E glass is the use of vacuum magnetron sputtering method on the glass surface coated with one or two or even three layers of silver layer of the film, to reduce the energy absorption or control of indoor and outdoor energy exchange, to protect life, work vity Comfort, and in order to achieve the purpose of environmental protection and energy conservation.
