Instructions for purchasing laminated glass



Wired glass is also known as shatterproof glass. It is made by heating ordinary flat glass to a red hot softening state, and then pressing the preheated iron wire or wire mesh into the middle of the glass，  Glass product  .

How to choose and use Laminated glass correctly?



Laminated glass is a general term for composite materials that are separated from glass or plastic by an intermediate layer and bonded together through treatment. The common and mostly used glass components are glass and glass, separated by an intermediate layer and bonded together through treatment. Laminated glass has high impact resistance and penetration resistance. When it is damaged by impact, under normal circumstances, foreign impactors will not penetrate, and glass fragments will not fly away from the bonding layer, but also can maintain a certain visibility, thus playing a role in safety protection. Safety Laminated glass refers to Laminated glass whose middle layer can limit its opening size and provide residual resistance to reduce the risk of cut or puncture when it is broken.



Compared with ordinary glass, Laminated glass has the following characteristics:



(1) High safety: brittleness is one of the characteristics of ordinary glass, which also determines its fragility. After ordinary glass is broken, a large number of pieces with acute angles and sharp edges will easily hurt people. Laminated glass makes up for this problem. After the Laminated glass is broken, the fragments are all adhered to a layer of film, and the fragments are close to small cubes without sharp corners and edges.



(2) High strength: the strength of Laminated glass is more than 4 times that of ordinary flat glass, which can withstand strong external impact. When Laminated glass is subjected to strong external impact, only radial cracks will be generated. Bulletproof glass is one of them.



(3) Strong sound insulation: the middle plastic material of Laminated glass has a good sound insulation effect, and the sound insulation effect is much better than ordinary glass.



(4) Strong radiation protection function: add ultraviolet absorbing materials to the middle film of Laminated glass, and Laminated glass will have a good ultraviolet absorption function, which can absorb 90% of the ultraviolet rays in the sun, eliminating the destructive effect of ultraviolet rays on people and objects. With this feature, anti radiation Laminated glass is commonly used in skylights and side windows of high-rise buildings, which is both beautiful and safe.



The buyers of Laminated glass include not only large real estate companies and automobile companies, but also ordinary people. The use of Laminated glass is often directly related to personal safety, so consumers who buy Laminated glass should generally pay attention to the following:



1. Determine which locations require or require the use of safety glass. In the "Regulations on the Management of Building Safety Glass", it is clearly stated that safety glass must be used in the following positions:



(1) Windows are installed outside buildings with floors 7 and above.



(2) Window glass with an area of more than 1.5m2 or french window whose bottom edge is less than 500mm from the final surface of the ground.



(3) Curtain walls (excluding all glass curtain walls).



(4) Inclined assembly windows, various types of ceilings (including skylights and skylights), and suspended ceilings.



(5) Sightseeing elevator and its outer enclosure.



(6) Indoor partitions, bathroom enclosures, and screens.

(7) Two pieces of Laminated glass with the same thickness, the one with more layers is better than the one with less layers;



(8) The impact resistance of Laminated glass will increase with the increase of thickness;



(9) Safety glass shall be used for railing glass not bearing horizontal load. If Laminated glass is selected, its nominal thickness shall not be less than 6.38mm. The tempered Laminated glass with a nominal thickness of not less than 12mm shall be used for the railing glass bearing horizontal load.
