Usually, the thickness of balcony glass is 10- 12 mm, but there are some differences between different glass materials, such as tempered white glass with a thickness of 6 mm and blue glass with a frame with a thickness of 4 mm. French window glass 1.2 cm or more. In addition, the higher the floor, the stronger the wind pressure, and the higher the requirement for glass thickness, which is safer. The purpose of sealing the balcony with glass is to transmit light and facilitate lighting. Second, it is conducive to ventilation, and opening windows can make indoor and outdoor air circulate. Third, ensure safety while being beautiful.
2. What kinds of balcony glass are there?
1. Ordinary white glass
Ordinary white glass is cheap, has not been calcined at high temperature, and has insufficient heat resistance and impact resistance. If subjected to external force, it is easy to break. Moreover, ordinary glass has different shapes when it is cut, and it is easy to hurt people after being broken. Purchase is not recommended.
2. Laminated glass
Laminated glass is made of two or more pieces of glass with a polymer film sandwiched between them, which is pressed at high temperature through a special process to make the glass and the film form a whole. Even if this kind of glass is broken in the later stage, it will not be punctured by fragments, because all its fragments will stick to the film to ensure safety.
3. Insulating glass
Insulating glass consists of two pieces of glass and an aluminum strip in the middle, and the four sides are sealed with glue, which can make the glass hollow and achieve the effect of heat insulation and sound insulation.
4. Tempered glass
Tempered glass is made of ordinary glass, and its hardness is higher than ordinary glass. It is also called safety glass, because the particles will not hurt people after the tempered glass is broken. In addition, it has high hardness and is not easy to break. When choosing tempered glass, pay attention to the 3c safety sign on it. But tempered glass cannot be cut and punched, otherwise it is useless.
