Laminated glass, as a kind of safety glass, will not produce sharp fragments after being broken by impact due to the bonding effect of the PVB film sandwiched between two ordinary glass. This effectively prevents the occurrence of debris puncture and penetration and falls, and ensures personal safety.
In the field of building doors and windows, in addition to providing safety, laminated glass has three major advantages:
Excellent sound insulation performance
Generally, the interlayer material of architectural laminated glass adopts PVB interlayer, and the PVB film has the damping function of filtering sound waves (reduces the volume transmission by reducing the vibration amplitude of the sound). Therefore, if you live in a place with severe road noise, it is right to choose a laminated glass with a PVB film thickness of 1.14 mm.
Innate UV protection
The PVB interlayer also has the function of filtering ultraviolet rays. The data shows that the PVB film can absorb more than 99% of the ultraviolet rays, thus protecting the indoor furniture, plastic products, textiles, carpets, artworks from fading and aging caused by ultraviolet radiation.
good energy saving performance
Because the laminated glass made of PVB film can effectively reduce the penetration of sunlight, the deeper the color and the lower the light transmittance, the stronger the ability of the laminated glass to block heat. Therefore, if there is sufficient light in the home, you may wish to choose laminated glass with medium light transmittance (50% to 70%).
Since the safety glass product certification was launched in 2003, most of the construction laminated glass manufacturers in the country have passed the product certification. The 3C mark is applied to the documents (such as the certificate of conformity). When purchasing a product, you must first check whether there is a 3C mark, and check whether the purchased product is within the scope of the company's ability to pass the compulsory certification and whether the certification certificate is valid through the Internet according to the company information, factory number or product certification certificate. -
