Acoustic Glass

Acoustic glass also named sound proofed glass, it can be laminated glass and insulated glass, even single panel help to reduce t he sound transmission. Acoustic glass create a quiet environment, for those areas especially a hearing test room or the operating room, it’s the top important need . Lanjing produces the acoustic soundproof glass solutions.

Acoustic Glass Types

Single Panels

As we know single panel glass has the function to block sound transmission, the thicker the glass is, the better sound transmission loss. Here is the sample:

Glass Configuration	STC/DB	OITC/DB
3mm	30	25
6mm	31	29
10mm	34	32
12mm	36	33

Laminated Glass

Laminated glass is the priority choice for sound proofing. With Eastman Saflex Q Acoustic PVB,

Eastman Saflex Q Acoustic PVB is better than normal PVB. Below is the comparison:

Glass Configuration	55.2 Lami	66.2 Lami	6-12-66.4	8-12-66.4	66.4-12-66.4
Normal PVB STC/DB	36	38	40.7	41.3	44.3
Eastman Saflex Q Acoustic PVB STC/DB	38	39	43.7	44.3	50.3

Insulated Glass

Insulated glass is made with two or more panels of glass with spacer, it definitely block sound transmission. both sides glass thickness different, the STC value better than both sides same thickness glass.

Glass Configuration	STC/DB	OITC/DB
6--12--6	35	30
8--12--8	37	32
6--12--8	38	33

Laminated Insulated Glass

Glass combined laminated and insulated glass together, the STC is much better than each glass. With Eastman Saflex Q Acoustic PVB ,it has better value.

Glass Configuration	STC/DB	OITC/DB
6--12--6	35	30
33.2 Lami	36	31
6-12-33.2	41	33

Ways to Create More Silent Environment

We know the glass thicker ,the sound proof value better, besides the glass thickness, are there any others factors effecting the sound transmission? Let’s see below:

Use Acoustic PVB

As we know Eastman Saflex Q Acoustic PVB is better than normal PVB.

Lanjing makes acoustic PVB laminated glass often, supply the better glass for client for better life.

Use Acoustic PVB

Use different thickness glass in one combination.

Whether the laminated glass or insulated glass, the both sides glass thickness different, the STC value better than both sides same thickness glass.

6+1.52+8 laminated glass

Make insulated air spacer thicker or multiple

The air spacer gets 1mm thicker, the blocking on sound transmission gets around 0.1 higher.

Make insulated air spacer thicker or multiple

6-12-6-12-6 insulated glass
