Heat absorbing glass is a kind of flat glass, which can absorb a lot of infrared radiation energy and maintain a high visible light transmittance.

The heat-absorbing glasses are gray, brown, blue, green, bronze, bronze, pink and golden yellow. At present, China mainly produces the first three colors of heat-absorbing glass. There are four kinds of thickness: 2, 3, 5 and 6mm. The heat-absorbing glass can also be further processed into polished, toughened, laminated or insulating glass. Heat-absorbing glass has been widely used in doors and windows of buildings, external walls and windshields of cars and ships, playing the roles of heat insulation, glare prevention, lighting and decoration.

(2) Heat reflective glass

Heat reflective glass is a kind of flat glass with strong heat reflective ability and good light transmittance. Heat reflective glass, also known as mirror glass, has many colors such as gold, brown, gray, purple, brown, bronze, light blue and so on.

Heat-reflective glass has a high thermal reflectivity, for example, the total reflection heat of 6mm thick float glass is only 16%, while under the same conditions, the total reflection heat of heat-absorbing glass is 40%, and the total reflection heat of heat-reflective glass can be as high as 6 1%, so it is often used to make hollow glass or laminated glass to improve its thermal insulation performance. Heat reflective glass coated with metal film also has the function of unidirectional image transmission. 3) laminated glass

Laminated glass is a flat or curved composite glass product made of PVB resin film sandwiched between two or more original glass plates and heated and pressurized. The original sheet of laminated glass can be ordinary flat glass, float glass, tempered glass, colored glass, heat absorbing glass or heat reflecting glass.

There are 2, 3, 5 and 7 layers of laminated glass, with a maximum of 9 layers. Laminated glass has good transparency and impact resistance several times higher than ordinary flat glass. Multiple layers of ordinary glass or tempered glass can be compounded to make bulletproof glass. Because of the adhesion of PVB film, even if the glass is broken, the fragments will not fly out and hurt people. By using different original glasses, laminated glass can also have durability, heat resistance and moisture resistance.

With high safety, laminated glass is generally used as doors and windows, skylights, windows and partitions of shops, banks and jewelry in high-rise buildings.
