Disturbing noise from the outside world enters the house mainly through the windows. Those living near busy streets, airports, or train tracks are constantly exposed to loud urban traffic. In the long run, this persistent noise not only disturbs concentration but can also lead to sleep disorders and other health problems.
If your windows are still single-glazed, then the noise from the outside world can pass through them almost unhindered. While DIY solutions like adding new silicone seals can offer minor improvements in sound insulation, they are often insufficient for significant noise problems.
However, near airports or busy roads, multiple layers of glass are usually not enough. For the living comfort of you and your family, you can use noise proof windows with soundproof glass as well as soundproof frames and thicker glass to greatly reduce the noise level.
Contact us now to order soundproof windows, Grandsea will provide high-quality door and window products to help you create a comfortable and quiet living atmosphere.
Sound proofing windows differ from ordinary windows in the structure of the window glass.
When sound waves strike a standard window, the glass pane vibrates. These vibrations transfer through the glass and into the interior air. While the noise is slightly muffled, it remains clearly audible inside.
To prevent this, modern soundproof windows are constructed asymmetrically:
To counter this, modern soundproof windows use an asymmetrical design. Typically, an outer pane of laminated glass (multiple layers bonded by a sound-dampening membrane) disrupts initial vibrations. This is combined with an inner insulating glass unit. The varied thickness of the panes and the air or gas-filled gap between them work together to dissipate the sound waves, preventing them from being transmitted indoors.
The strength of the soundproofing depends mainly on the size of the space between the glass panels and the thickness of the glass panels.
In general:
In addition, the space between the glass panels of sound dampening windows is filled with an inert gas, just like in the case of insulating glass. This also further increases the soundproofing effect.
High-quality soundproof windows from Grandsea make it easy to block out noise. By eliminating the disturbances that disrupt sleep, effective soundproofing makes a vital contribution to your well-being. Because whether in an apartment or in a private living space, it is absolutely necessary to relax from everyday life.
In order to achieve the best soundproofing effect with a noise reduction of up to 94%, we strictly control the manufacturing processes and standards of sound resistant windows. The decisive factors for effective soundproofing are the frame and glass used for soundproof windows. Since customized window production is allowed, the windows can be adapted to the needs of different customers. Depending on the thickness and quality of the glass, the shape of the glass is also an important component of the soundproofing effect. The greater the difference in thickness between the outer and inner glass, the better the soundproofing effect.
To know whether you need noise reduction windows, you can look not only at your subjective feelings, but also at the classification of the corresponding windows: Modern windows are divided into 6 soundproofing levels. The higher the soundproofing level, the higher the soundproofing effect. Choosing the right soundproofing level depends on the noise level of the environment in which you live and your subjective feelings.
Windows are particularly important in terms of soundproofing, especially outdated windows, which have a poor soundproofing effect compared to exterior walls.
It is also important to find the right balance. While soundproofing is beneficial, an excessively high level can sometimes lead to an overly isolated feeling or may impact natural ventilation if not planned correctly. Our experts at Grandsea will help you select the perfect level of soundproofing for your needs, avoiding any potential downsides.
To get a guide in advance for the required soundproofing, you can use the different soundproofing levels as a guide. According to international standards, soundproofing windows are divided into six soundproofing levels, which are subdivided according to the degree of soundproofing. The soundproofing index indicates how much annoying noise from the outside world is blocked through the window. Windows with a soundproofing rating of 3 reduce penetrating sound by 30-35 dB. A 10 dB reduction in decibels is perceived by the human ear as half the volume.
Start by ensuring your windows are properly sealed.
Not only noise but also cold and moisture can penetrate through small gaps between the window and the wall, especially through the window or door frame. You can use a candle to test if air is getting in: where the flame flickers, there is a leak. A simple method is the paper test: place a piece of paper in the window frame and close it. If you can pull the paper out without it tearing, your window seal is not tight enough. If this is the case, you can seal the affected area with self-adhesive sealing tape. You can fill small holes between the window and the wall with sound proof window inserts such as sealants.
Soundproofing | Soundproofing level | Price per window sash(aluminum) |
20-25 dB | Level 1 | $100 |
25-30 dB | Level 2 | $140 |
30-35 dB | Level 3 | $180 |
35-40 dB | Level 4 | $230 |
40-45 dB | Level 5 | $280 |
45dB 以上 | Level 6 | $320 |
The key difference lies in the construction. Soundproof windows utilize a multi-layer, asymmetrical glass structure, often incorporating laminated glass and specialized air or gas gaps. Combined with superior sealing technology, this design can block up to 95% of external noise—a level of performance ordinary windows cannot achieve.
Performance is measured using the STC (Sound Transmission Class) rating. A higher STC rating indicates better sound insulation. While standard double-glazed windows typically have an STC rating of 26-28, our high-performance soundproof windows can achieve ratings of STC 45-55, effectively blocking the majority of external noise.
Absolutely. In addition to superior sound insulation, our windows provide excellent thermal performance, which can lower your energy bills. The multi-layer glass also enhances security by increasing impact resistance, making it a smart, multi-faceted investment in your home.
Not at all. We use high-transmittance glass to ensure there is no significant impact on natural light. Our windows operate just like standard windows for ventilation, and we can also incorporate trickle vents into the design to maintain air circulation even when closed.
We offer a variety of frame materials, colors and styles to perfectly match the decoration style of your home. In addition, we can also customize the soundproofing level according to your specific needs to ensure that we provide you with the most suitable solution.
