Recently, some netizens said on the Internet why the market is equipped with insulating glass instead of laminated glass. Theoretically and practically, laminated glass is better than insulating glass in terms of sound insulation, heat insulation and heat preservation, then why do merchants choose hollow glass instead of laminated glass? The reason is very simple that the cost of laminated glass is high.
At present, the hollow laminated glass on the market is divided into 0.38mm,0.76mm,1.14mm and other thickness according to the thickness of PVB clip. The price of laminated glass with different thickness is different, therefore, if the hollow laminated glass is configured, the cost will be very high, so the basic configuration is hollow glass. Compared with laminated glass, hollow glass is cost-effective, although the effect of sound insulation and heat insulation is no better than that of laminated glass, compared with single-layer glass, the sound insulation and heat insulation of hollow glass is obviously better than that of single-layer glass, so the standard configuration of doors and windows on the market is double glazing unit, there are conditions to choose three-layer hollow glass, or even better hollow laminated glass.
Three-layer hollow glass
the conclusion is that in terms of sound insulation and heat insulation effect: Hollow laminated glass> three-layer hollow glass> double glazing unit> single-layer glass, in short, choose the glass configuration according to the personal budget, laminated hollow glass is definitely better than pure hollow glass.
So how should consumers choose the glass configuration of doors and windows?
Answer: double-layer hollow tempered glass is selected as the basic standard. If the insulation effect is better, three-layer hollow glass is selected. If the house is located in noisy areas such as main roads, it is better to choose hollow laminated glass.
What are the advantages of choosing laminated glass?
Advantage 1: explosion-proof effect: laminated glass, as a kind of explosion-proof glass, will absorb a large amount of impact energy and weaken it rapidly when it is broken by any external impact force. Therefore, even if the glass is broken, it can still be completely kept on the original frame, and the human body will not be hurt by Splash glass fragments. Because the glass adopts multi-layer interlayer, it can produce multi-level explosion-proof glass, it has high toughness and strong adhesion. Even if it is broken, it will not fall to the ground and remain in place. It has good hardness and wind resistance.
Advantage 2: UV protection: laminated glass its interlayer also has the function of filtering ultraviolet rays. PVP film can absorb more than 99% of ultraviolet rays, thus protecting indoor furniture, plastic products, fading and aging caused by ultraviolet radiation-free textiles, carpets, artworks, etc.
Advantage 3: Noise Reduction: PVP film has barrier absorption effect on sound waves.
In short: if you have the conditions, you can use laminated glass for money. If you want to be economical, you can choose double glazing unit.
