Laminated glass is characterized by transparency, superior mechanical strength, heat resistance, moisture resistance and cold resistance. Compared with common glass, it has superior performance in safety, security, noise insulation and radiation resistance.
1, Extremely high safety and security:With excellent performance in earthquake resistance, shock resistance, penetration resistance, wind pressure resistance and strong PVB adhesion, laminated glass will not result in bodily injury from splashing splinters when it is struck and broken due to external force; it can withstand the attack of burglar's tools, such as hammer and brick. It can improve the penetration resistance by increasing the thickness of the PVB film.
2, Good Acoustic Insulating Performance:PVB film can effectively absorb sound waves and reduce noise pollution;
3, Anti-UV linearity: without loss of visible light at the same time, it can effectively block nearly 99% of the UV into the house and prevent the interior decorations and furniture from fading and aging.
4, Color diversity: according to the needs of customers to produce a variety of colors or patterns of products to meet the engineering design requirements;
5, Thermal Insulating Performance: effectively block the heat transfer, reduce heat transmission, reduce cooling energy consumption;
6, Ballistic performance: through the different thickness of the PVB and the combination of several pieces of glass, it can be made of bullet-proof glass and some high-strength decorative glass or engineering structure glass;

Status of breakage
|
Laminated glass
|
Security breakage: it might be broken by a pendulum impact, but the glass remained whole, and the pieces and splinters adhered firmly to the interlayer.
|
Annealed glass
|
Broken once get hit, the typical breakage status: bring many elongated sharp splinters
|
Tempered glass
|
Unbroken unless at the huge impact: glass was broken and burst into numerous particles
|
Wired glass
|
Similar with common annealed glass in the status of breakage
|
Coated annealed glass
|
PET film on glass surface can provide additional protection; glass is fragile, and splinters flew toward the inside when the surface film was separated from the broken glass.

3, Acoustic Insulating Performance
Acoustic insulation is another prominent feature of laminated glass in addition to security and thermal insulation. In order to create a comfortable living environment, control of noise has become an important issue in modern architecture.
In general, human auditory system can automatically convert the 10 times acoustic intensity into twice acoustic intensity to create human actual feeling. The loudness of sound audible to the human ear is generally presented in decibels (dB). The sound less than 3dB is inaudible and 5 dB is audible to the human ear, and the maximum tolerable loudness of sound is 130dB. Laminated glass controls noise mainly through absorbing noise and degrading sound energy. Noise reduction is generally measured in weighted sound isolation. Table 1-5 shows the weighted sound isolation of various types of laminated glass.

Factors affecting the weighted sound isolation of laminated glass include glass thickness and acoustic damping of the interlayer of laminated glass. Table 1-5 shows that, with the same glass substrate, the weighted sound isolation of laminated glass varies depending on the thickness of the PVB film, and the thicker the PVB film, the better the acoustic insulation.
