How Do Soundproof Windows Work?
Improve your comfort with soundproof windows
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.

Soundproofing index
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Windows are particularly important in terms of soundproofing, especially outdated windows, which have a poor soundproofing effect compared to exterior walls.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.
How can you soundproof a window on a budget?
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.

What is the primary difference between soundproof and ordinary windows?
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.
How is the performance of soundproof windows measured?
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.
Do soundproof windows offer benefits besides noise reduction?
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.
Will soundproof windows reduce the natural light or ventilation in my 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.
What are the customization options for your soundproof windows?
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.
