Three Advantages Of Laminated Glass For Doors And Windows

As people's requirements for quality of life increase, they also require higher configurations and a more perfect experience in door and window glass. Therefore, laminated insulating glass has become the pursuit of many consumers with the performance of home decoration doors and windows. Today, Minglei and Let’s talk about laminated glass.

What is laminated glass?

Laminated glass (also known as laminated glass, explosion-proof glass) is made of two or more pieces of float glass sandwiched with a strong PVB (ethylene polymer butyrate) film, pressed together by a hot press to expel the air in the middle, and then It is a composite glass product made by putting a small amount of residual air into the adhesive film by using high temperature and high pressure in a high-pressure steam kettle. In addition to PVB, laminated glass interlayer films also include SGP (ionic interlayer film), EVA (ethylene-vinyl acetate copolymer), etc.‌

Advantages of laminated glass

Safety

The light transmittance of PVB diaphragm can reach more than 90%, and the refractive index is almost the same as glass; it does not harden when it is higher than -50℃, and has good bonding performance at 130-140℃. At this temperature, high pressure is used to bond the glass with it. When pressed, the glass is firmly bonded to the middle layer material. Therefore, laminated glass has high strength, elasticity and penetration resistance, and can withstand huge impact forces.

Sound insulation

If laminated glass is compared with insulating glass, the sound insulation performance effects from high to low are: double laminated insulating glass > laminated insulating glass > insulating glass. The mid- and low-frequency noise that insulated glass cannot solve can be well solved by laminated glass. This is because the PVB diaphragm between the laminated glass can hinder and buffer the vibration of the glass and block the transmission of noise, especially the isolation effect of mid- and low-frequency noise.

Energy saving

Laminated glass has a natural ability to protect against ultraviolet rays. The PVB film in the middle can absorb more than 99% of ultraviolet radiation. The principle is to absorb ultraviolet rays through organic ultraviolet absorbers and organic ultraviolet blockers in the PVB film, converting ultraviolet radiation into heat energy. Loss, through the inorganic ultraviolet reflector, it plays the role of reflecting and scattering ultraviolet rays, and by adding "vanadium" to reduce the shading coefficient, it has the functions of energy saving and discoloration. Therefore, when sunlight directly illuminates a piece of colorless laminated glass, the PVB interlayer film can absorb part of the heat and only transfer part of the heat to the room, thereby maintaining the indoor temperature and saving air conditioning consumption.

Applicable scenarios for laminated glass

The most common situations for installing laminated insulating glass doors and windows in home decoration are the following three situations:

1. The home is on a mid-to-high floor, and the standard purchase of exterior doors and windows is tempered insulating glass. However, considering the risk of glass self-explosion, consumers add laminated glass for safety reasons.

2. The home is close to noisy places such as streets, roads, elevated roads, etc. In order to improve the sound insulation effect of doors and windows, the insulating glass is upgraded to insulating laminated glass.

The city you are located in does not have a suitable climate all year round. The home needs to be built as a closed sunroom with a glass top surface and no suspended ceiling. In order to improve the heat insulation performance, the standard laminated glass on the top surface is added. Insulated laminated glass. 

FAQ

Color change

When using laminated insulating glass at home, because the total thickness of the glass is thicker, the light transmittance of the entire glass may be low and the glass may become green. Especially when replacing laminated insulating glass for the whole house, it will feel incongruous when compared with other glass. And please note that after Low-e glass and white glass are made into laminated glass, there is a big difference in color from double white glass laminated glass. Therefore, when consumers are purchasing, it is best to ask the merchant if there is any physical comparison and see for themselves acceptance level. When making glass configurations, it is best not to have too big a gap in the glass configurations of doors and windows in the same space.

Performance options

When the home has higher thermal insulation requirements (the K value of insulating laminated glass is similar to that of insulating glass), it is recommended to add single silver Low-e to the insulating laminated glass first, then double silver Low-e, and thirdly argon gas. Then warm edge, and finally three silvers.
