Q: From an acoustic perspective, what configuration is required for vacuum glass to achieve Rw+Ctr ≥ 40dB?

A: Vacuum glass that is integrated with both laminated and insulating layers can reach an Rw+Ctr of 40dB.

Eg: A configuration such as 6+1.52PVB+6+20A+6+0.3V+6 achieves a measured sound insulation of 45 (-1;-5) dB.
