Bent Laminated Glass:

Bent Laminated Glass is a combined glass composed of two or more pieces of glass which are bonded firmly with SGP, PVB,EVA and PU interlayer. With different Tint interlayer films, those base-glass can compose of nice glass at bent shape.

Laminated glass is characterized by excellent shock resistance and penetration resistance. When it is hit, it generally will not be penetrated by the external impactors, and the glass splinters will not fly away from the interlayer. That is why it is also called security glass.

Features:

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, sound insulation and radiation resistance.

1, Extreme High Safety and Security:

With excellent performance in shock resistance, penetration resistance, wind pressure resistance and strong interlayer adhesion, laminated glass would not lead to bodily injury from splashing glass splinters when it is impacted and broken due to external force; it can withstand the attack of tools, such as hammer and brick.The penetration resistance can be improved by the increasing on the interlayer thickness. The parameter comparison on impacting resistance parameters is shown as follows:

2, Thermal Insulating Performance

3, Acoustic Insulating Performance

Acoustic insulation is another main 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.

Table 1-5 Weighted sound isolation 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.
