How to increase glass sound transmission loss
Despite shield,light transmission etc,one of the most important function of architectural glass is noise control.
balustrade glass will decrease the noise significantly and create silent and quite environment.In auto ,many high end brands use laminated glass instead of single piece tempered glass to increase the sound transmission loss.As part of the building, whether the concrete wall,floors etc ,they’re thick and have good sound transmission loss.As the thinnest part of the building ,glass is usually only several milimeter thick,some insulated glass are 24mm thick,glass has been the weakest point of the building noise conductivity materials,here we introduce the factors that affect glass STC and measures to increase glass STC.
1.Glass thickness.Increasing glass thickness is the most important measurement.
3mm thick monolithic glass, glass STC is only 30Dbs,when glass thickness was increased to 12mm thick,glass STC can reach 36Dbs,whether it’s single piece monolithic glass,laminated glass,or insulated glass,the thicker total glass thickness,the better sound transmission loss.
2.PVB or other interlayer used in laminated glass.
PVB or SGP,EVA, these materials are soft materials ,it can decrease the vibration and work as good barrier for sound transmission.Meanwhile,the thicker PVB interlayer,the better sound transmission loss cause by the interlayer.
3.Air space thickness.Thicker air space for insulated glass will increase sound transmission loss.For example, 3-10A-3 insulated glass STC is 3Dbs higher than 3-6A-3mm glass.
When the spacer becomes thicker,STC will be better.
Here is a simple chart showing the typical glass STC value:
Glass combination Glass type Glass thickness STC(Dbs)
6mm glass Monolithic 6mm 31 Dbs
6+1.52PVB+6 Laminated 13.52MM 39 Dbs
6+12A+6 Insulated 24MM 35 Dbs
6+12A+6+12A+6 Triple insulated 42MM 39 Dbs
6+12A+6+1.52+6 Laminated Insulated 31.52MM 43Dbs
The conclusion shows thicker and better glass combination will increase glass STC ,of course this will bring the increased costs in glass.
In most cases,40 Dbs has been very excellent in architectural application.So most laminated insulated glass ,and laminated glass are satisfy most project requirement.
Here we also offer several related resources to check the glass STC for clients before designing the project.
1.Viracon:The performance data below applies to an
insulating unit constructed with two plies of glass and an air or argon filled space. Data is based on testing ~ 36" x 84" glass to ASTM E413-87 in an acoustical wall. AGC glass China is estimated based on this test. Glass size and glazing system will afect STC rating. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance.

Multipurpose bulletproof glass for complete protection
Every time we put in glass application at home, or in the shop-front or any other areas, we are frightened about one particular truth: will it be broken? Will we get harmed?
This article addresses responses to all such items. Now we can set up basic safety glass for tailored programs with no possessing to dread of receiving harmed if we stay inside a glass-primarily based place. The initial critical property for this is that anti bullet glass does not crack or shatter. It functions as a protect.
Also, if the glass surface receives a hit by some item, it will shatter into pieces. This is not the case for bulletproof glass. The surface layer of bulletproof glass provides resistant. The dimension can assortment from 3 to ten mm. consequently can cease sharp item to penetrate. The glass layer is composed of a polycarbonate layer and an interlayer of plastic. They are also found in credit score unions.
Bulletproof glass is utilized in banking institutions as properly as in-store fronts and counters exactly where we uncover the workers functioning in a space put in with glass. interpane glass China is a popular phenomenon in New York and other areas.
In terms of protection, it delivers a thousand times far more security as compared to any typical type of glass. The dimensions are tailored starting from three centimeters. The glass is segregated into several forms like that of kind I. kind II-A, kind II, variety IIIA, kind three, variety four.
Bulletproof glass is ideal identified for giving safety, which is why they are utilized in recovery vehicles(armoured autos) for defence. Our marines can remain protected without having obtaining to dread an oncoming bullet hitting them. It finds in depth use in automobiles used by celebrities and politicians. Bear Glass does ballistic glazing in accordance to the requirement of customers.
This glass is also utilised in workspaces so that businesses can stay safe and protect their office from any type of theft.
It is known for its large plastic energy potential which can even maintain the damages induced by projectiles or bullet. Bullet resistant glass, in other words and phrases, is manufactured up of two levels. https://www.cnmorn.com/frameless-vs-framed-shower-doors.html is all set to endure all physical threats ie brittle glass. On the other hand, the within layer is produced up of a flexible polycarbonate layer.
Even if there is any danger on the outside the house, it would not have an effect on the particular person sitting down inside of the glass construction as bomb-proof home windows.
Bear Glass fabricators advise a number of typical varieties of this kind of glass. Among all the varieties, the plastic glass-clad carbonate is one of the most well-liked indicates of strongest bulletproof glass at any time employed by us for our buyers.
The layer delivers much more energy as in comparison to other levels of glass.
building glass quality where bulletproof glass is utilized is in reputed jewelry shops. The owners desire to maintain then total store place stylish. At the same time, they want some secured firm of glass which can defend the inside of jewelry obtainable, from getting taken absent by intruders. It is even discovered in cars that are employed by embassies.
