Acoustic Insulation

See how our soundproof windows can turn your noisy environment into a quiet and peaceful one.

Do you find yourself constantly bothered by external noises that disrupt your peace and quiet? Is your home or office environment filled with unwanted sounds that hinder concentration and productivity? If so, you're not alone. Noise pollution has become a growing concern in our modern lives, affecting our well-being and overall quality of living or working spaces.

At Doorwin, we understand the importance of creating a serene and tranquil environment where you can escape the distractions of the outside world. That's why we offer cutting-edge solutions for acoustic insulation, specifically tailored for windows and doors. Our acoustic insulation solutions are designed to minimize noise transmission, providing you with a peaceful and comfortable space to live, work, or relax.

How Do Acoustic Insulated Windows & Doors Work?

Noise Travels in Two Different Ways
- Through the Air and Through Materials.

There are two measurement methods- by Sound Transmission Class (STC) and Outdoor/Indoor Transmission Class (OITC).

Today, most standard insulated windows have an STC rating around 26. These double-glazed windows feature two layers of five-millimeter-thick glass. By adding more window glass, there is more insulation, which helps dampen outside noise.

Acoustic Insulated Windows & Doors work by slowing the transmission of sound waves, making them appear quieter. Sound waves can be absorbed, reflected, or minimized as they travel through different materials. In windows, this can be achieved by optimizing air space, mixing glass thicknesses, or adding additional glass panes. The selection process of these different properties of the window is critical to the sound attenuation performance. Using high-quality materials, such as lab-tested weatherstripping on windows, is also a proven way to ensure performance. However, it is more than window features that help support noise reduction. Another most important element of performance is installation. Proper installation helps ensure a seal and helps prevent noise. From choosing window properties to ensuring proper installation, working with a Doorwin expert can make the process simple and easy to understand.

86S Alumnium-Clad Wood Windows & Doors

Acoustic insulation is a vital consideration when it comes to creating a peaceful and noise-free environment in your home or office. It helps to reduce sound transmission, ensuring that unwanted noises from the outside world are kept at bay. At Doorwin, we offer a range of acoustic insulation solutions, and our 86S aluminum-clad wood series windows are specifically designed to provide exceptional soundproofing capabilities.

Our 86S aluminum-clad wood series windows combine the best of both worlds: the natural insulation properties of solid wood and the durability and low maintenance of aluminum cladding. This unique combination offers numerous benefits, including superior acoustic insulation. The solid wood materials used in our windows act as natural absorber, effectively reducing sound transmission and creating a quieter indoor environment.

Sealing Strips

To further enhance the acoustic performance of our windows, we incorporate advanced technologies. Our windows feature Technoform™ sealing strips, which provide a perfect seal and tightness, minimizing the passage of sound waves. This innovative sealing system ensures that your space remains tranquil and undisturbed by external noise.

Glass Configuration

The glazing of our 86S series windows is also designed with acoustic insulation in mind. We offer double- or triple-pane laminated glazing options, which consist of multiple layers of glass with a specially formulated interlayer. This interlayer helps to absorb and dampen sound vibrations, significantly reducing noise transmission. Additionally, our windows feature Low-E coatings and are filled with argon gas to further enhance their insulation properties and improve the Sound Transmission Class (STC) and Outdoor-Indoor Transmission Class (OITC) ratings.

In addition to the exceptional acoustic insulation features, our 86S aluminum-clad wood series windows are equipped with a state-of-the-art German-imported hardware system and multi-point locks, further enhancing their performance and functionality. These meticulously engineered components have been specifically designed to ensure precise operation and optimal sealing when the windows are fully closed.


The German-imported hardware system is renowned for its superior quality, durability, and smooth functionality. Every detail has been carefully crafted to provide a seamless and effortless user experience. The multi-point locking mechanism offers enhanced security, firmly securing the windows at multiple points along the frame, providing peace of mind and an additional layer of protection.

When combined with our Technoform™ sealing strips, these high-precision hardware components contribute to a superior sealing effect, effectively preventing the infiltration of external noise. The tight and secure closure achieved by our multi-point locks, along with the insulating properties of our solid wood profiles and advanced glazing options, results in an unrivaled acoustic insulation solution for your space.

By addressing the root cause of noise infiltration, Doorwin’s acoustic insulation solutions effectively block, absorb, or dampen sound waves, creating a soundproof barrier between you and the outside world. Whether you reside in a bustling urban area, near a busy road, or even close to an airport, our high-quality products and expertise can significantly reduce unwanted noise, allowing you to enjoy a quieter indoor environment.

We believe that acoustic insulation should never compromise style and aesthetics. That's why our solutions are not only highly functional but also customizable to suit your specific design preferences. With a wide range of styles, materials, and finishes available, you can achieve both exceptional noise reduction and a visually appealing look that complements the overall aesthetics of your space.

One stunning example of our craftsmanship and design can be seen in the prestigious residence located at CA . In this remarkable project, all the exterior and interior windows and doors were supplied by Doorwin, showcasing the seamless integration of our products into a luxurious living space. The owner's meticulous attention to sound insulation was of utmost importance. Understanding the significance of creating a peaceful and tranquil living environment, Doorwin was chosen to provide the windows and doors that perfectly met their requirements.

Every aspect of the project was carefully considered, from the selection of materials to the design and installation process. Our team worked closely with the owner to ensure that their vision for superior sound insulation was brought to life. The result is a home that not only showcases exceptional craftsmanship and aesthetics but also provides an oasis of calm and serenity.

The residence features a variety of special-shape windows and doors, including exquisite arch top double windows and double doors. These architectural elements add a touch of elegance and grandeur to the property, enhancing its curb appeal and making a bold statement. The windows and doors are meticulously crafted with aluminum-clad solid red oak wood, combining natural beauty with modern design sensibilities.

The rich texture and grain of the solid red oak wood bring warmth and character to the house, creating a welcoming and inviting atmosphere. The aluminum cladding provides exceptional durability and low maintenance, ensuring that the windows and doors will continue to impress for years to come.

By incorporating triple-pane laminated glazing, Low-E coating, and argon gas filling, these windows and doors achieve remarkable Sound Transmission Class (STC) and Outdoor-Indoor Transmission Class (OITC) ratings. This ensures that unwanted external noise, whether it be traffic, construction, or other disturbances, is effectively minimized, allowing for a truly serene and tranquil living space.

The owner's careful consideration of sound insulation issues, coupled with our expertise and commitment to excellence, resulted in a residence that surpasses expectations. The combination of the owner's vision and Doorwin's dedication to quality craftsmanship and acoustic performance has created a haven of peace and tranquility.

The residence is a testament to the seamless fusion of form and function, showcasing the exquisite design and superior performance of our 86S aluminum-clad wood series windows. It stands as a testament to the transformative power of our products, elevating spaces and creating environments that are both visually striking and acoustically serene.
