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.
