Sound Insulation PVB Film

Product details

The average sound insulation is about 35-42 dB, and it has an outstanding effect on high-frequency noise (such as traffic noise and human voice), which can reduce noise by 30-40 decibels ( equivalent to 70 decibels of noise to 30-40 decibels). Tempered glass: The sound insulation of ordinary air layer (12mm) is about 28-32dB, which can be easily adjusted to 30-35dB after filling with inert gas. The blocking effect on low-frequency noise (such as engine roar) is somewhat poor. Summary and remarks. If you want extreme sound insulation (such as houses near heated railways and main roads), vacuum glass is preferred, but it should be recommended that its cost is significantly high; If it is for daily sound insulation (such as ordinary residences and offices), insulated glass (especially thick air layer + inert gas filling) can meet the needs and is more comfortable .
