Superior Soundproof with Laminated Glass

Our Quietglass windows are engineered to be the most effective soundproof windows in the world. They utilize a combination of vacuum and laminated glass with an aluminum frame to create a near-impenetrable barrier between outdoor noise and your ears. With the ability to block up to 90% of external sounds, our windows provide superior sound control. Our products achieve impressive Sound Transmission Class (STC) ratings of up to 58, outperforming most other window products in the world. Additionally, our windows are particularly adept at blocking high-frequency noises, resulting in outstanding acoustic performance.
We are the best on sound proof
We stand out as the best because of our advanced window structure. Our windows use a combination of vacuum insulated glass (VIG) and laminated glass to effectively block outdoor noise and minimize sound transmission. Our window products boast exceptional acoustic performance in high-frequency bands, with an impressive average Sound Transmission Class (STC) rating ranging from 45 to 58. This level of performance is unparalleled around the world.
Quietglass sound barrier is as good as brick walls
Our windows are designed to be as quiet as brick walls. While single-pane windows typically have an STC rating of around 21 and double-glazed windows have an average rating of 26, a typical 4" brick wall has an STC of 45 and can be made even quieter by incorporating additional insulation materials. With our windows, you can achieve the same level of noise reduction as a brick wall, blocking out outdoor noise and maintaining a peaceful indoor environment.

 

Soundproof performance

Our windows utilize a combination of VGI, laminated glass, and aluminum frames, providing a soundproof solution that incorporates the technological advantages of all three materials. VGI and laminated glass outperform standard double-pane glass, while the aluminum frame, with its thermal break, is far superior to vinyl in preventing the transfer of vibrations from the outside to the inside through the frame. Our product line includes a range of options for soundproof requirements, including fixed windows, swing windows, tilt and turn windows, top-hung windows, and sliding windows. Our offerings range from our most economical option (6-8Ar-8-12Ar-6-0.76PV-6), which has an average STC of 45, to our best soundproof option (6-0.76PV-6-6Ar-6-0.3V-6-3Ar-6-1.52PV-6), which has an average STC of 58. These options are designed to meet the diverse requirements of our customers.

Compare STC with traditional windows

STC is used to measure a window’s ability to reduce sound. The higher the rating, the better the sound control.

Window Type

STC

Regular double-pane windows

up to 33

Laminated double-pane windows

up to 38

Triple-pane windows

up to 48

Quietglass Sound proof windows

up to 58

 

What affects windows sound features?

For a window to be considered "soundproof," it should be capable of blocking approximately 90% to 95% of outdoor noise, which typically corresponds to a rating of 45 to 50 on the STC scale. Several factors can influence a window's sound transmission, including the window's composition, glass thickness, the space between panes, and the type of gas used in the space (air, argon/krypton, or vacuum). Windows with vacuum and laminated glass offer superior soundproofing qualities compared to regular insulated windows. 

 

Vacuum and laminated glass perform better to block noise

 According to most experts, if you want windows with superior soundproofing capabilities, you should opt for either vacuum or laminated glass. Vacuum insulated glass (VIG) is made up of two panes of glass with a vacuum layer between them. Thanks to the vacuum layer, VIG offers sound insulation performance that is approximately 10 dB higher than that of regular insulated glass units (IGUs).

Laminated windows, on the other hand, have a transparent layer of plastic sandwiched between two outer layers of glass panes. This plastic insert effectively deadens noise and vibrations that can otherwise easily transmit through glass.

Our unique design for soundproof windows

A. Different frequency bands of noise can be filtered out by varying the spacing between glazing.

B. Varying glazing thickness to block out low fequence noise.
