Tested under real-world conditions—not just a marketing figure
Our curtain was measured by Daidalos Peutz, an independent BELAC-accredited laboratory, in accordance with the international standard NBN EN ISO 10140-2:2010. These photos show the complete testing procedure—installation in a test bay, reverberation chamber, and calibrated microphone. A seller without these photos has not conducted a test.
Installation of the curtain in the test bay — emission chamber
Microphone calibrated in a reception chamber — measurement of sound insulation
Complete setup in a reception hall — ISO 10140-2 protocol
Front view — curtain in the bay, microphone positioned for measurement

Patented technology — a true textile barrier
Cotton Silence curtains use patented multi-layer technology designed to create a fabric barrier in front of vulnerable areas: windows, doors, picture windows, or entryways.
The curtain helps reduce some outside noise while improving the room's thermal comfort.
Performance always depends on the specific configuration: dimensions, installation, glazing, seals, the roller shutter box, and any air leaks.
-
Proven performance — independent laboratory testing
Cotton Silence is backed by an official report from an independent European laboratory that tested the entire curtain, with sound reduction measured at up to -28.2 dB under specific test conditions.
This is a major advantage over curtains that are simply “thick” or decorative, which are often sold without any solid evidence of their effectiveness.
Actual results may vary depending on your home, but our promise is clear: a high-performance, custom-fit, patented fabric solution designed for real-world, everyday use.
-
Premium quality — custom-made and ready to install
The Cotton Silence curtain combines premium fabric, professional craftsmanship, and a technical design tailored for everyday use.
Each curtain is custom-made to your specifications to ensure a better fit for the area you want to cover and to avoid an ill-fitting result.
The goal: an elegant, durable solution that’s easy to incorporate into a bedroom, living room, office, or in front of a door exposed to noise.
FAQ – All About Cotton Silence Curtains
What kind of " noise-reducing curtain " should you choose for a bedroom that faces the street?
For a bedroom that overlooks traffic, opt for a heavy, multi-layered, custom-made curtain that completely covers the window—ideally extending beyond the sides. This setup is the most effective at blocking out outside noise and ensuring a good night’s sleep.
Does a " soundproof curtain " also insulate against heat and cold?
Yes. The dense, multilayered structure that reduces noise also limits heat transfer. A single Cotton Silence curtain therefore provides both acoustic comfort and thermal insulation, in both summer and winter.
What makes a soundproof curtain truly effective?
Three factors: mass (a heavy fabric blocks sound waves more effectively), a multilayer structure (each layer absorbs some of the sound energy), and a precise fit around the window or door, since gaps along the edges significantly reduce effectiveness. That is why custom-made solutions are crucial for high- noise-reducing curtain .
How many decibels can a soundproof curtain reduce?
The degree of noise reduction depends on the curtain's construction and the frequency of the noise. Entry-level soundproof curtains often reduce noise by only a few decibels. Our patented multilayer technology achieves significantly higher levels of noise reduction, as validated by acoustic tests conducted by the independent Peutz laboratory—a measured figure, not a marketing claim.
What is the difference between a soundproof curtain, an acoustic one, and a noise-canceling one?
These terms are often used interchangeably, but they refer to two different concepts. A " noise-reducing curtain " (or "phonic") curtain reduces noise coming from outside a room, such as traffic or neighbors. An " acoustic curtain " curtain improves acoustic comfort inside the room by reducing echo and reverberation. Cotton Silence curtains are designed to address both of these aspects.
Why is Cotton Silence more expensive than some noise-reducing curtains sold online?
Because a soundproof curtain can’t be judged solely by its appearance or a decibel rating.
Some low-cost soundproof curtains use standardized designs, with basic lining and bold claims. They may sometimes provide a slight improvement in comfort, but they should not be confused with a high-end soundproofing solution.
Cotton Silence features a multi-layer design, custom tailoring, double-sided fabric finishing, and performance measured in an independent European laboratory according to test protocols.
Before comparing prices alone, you should compare the evidence: laboratory testing, test protocols, weight, construction, dimensions, installation, and real-world usage conditions.

How Do Cotton Silence Noise-Reducing Curtains Work?
They use patented multi-layer technology designed to create a fabric barrier in front of a window, door, or glass wall. The curtain helps reduce some noise pollution while improving thermal comfort. The results always depend on the dimensions, installation, and weak points of the home.
Do You Need a Specific Track for Good Performance?
To achieve the best results, track installation is generally recommended, as it provides more continuous coverage.
You can also choose 40 mm grommets on a standard rod for a simple and decorative installation.
The more the installation minimizes the space around the curtain, the better the result will be.
How to Easily Install a Cotton Silence Curtain?
Installation is still simple:
• On a rod → classic eyelet attachment
• On a rail → can be mounted on the ceiling or wall, depending on the setup
Before ordering, check the width, height, and overhangs required to fully cover the area you want to protect.
What's the Difference Between Flat Pleats and Eyelets?
Eyelets: easy to install, attractive, and suitable for a curtain rod.
Rail-guided roller: more consistent coverage, better coverage, and a more technical finish.
For maximum performance, a rail is usually the best choice.
Where Are Cotton Silence Curtains Made?
Cotton Silence curtains are manufactured in Europe by textile professionals and undergo strict quality control before shipping.
How to Care for Your Curtains Without Damaging Their Effectiveness?
You can gently brush or vacuum them. Our premium fabric is super durable and keeps its acoustic performance over time. Just don't machine wash or dry clean them, as that could mess with their internal structure.
Can I return a curtain if the size isn't right?
Yes, for standard models.
However, custom-made models can't be exchanged since they're made specifically for your dimensions.
Does the product come with a warranty?
Yes. Cotton Silence covers manufacturing or material defects discovered upon receipt, subject to the terms and conditions applicable to custom-made products.
How long does delivery take?
Our curtains are made to order. Please allow 4 to 6 weeks between order confirmation and shipment, depending on the time of year and the specific design.
What is Cotton Silence's return policy?
Cotton Silence offers a flexible return policy for satisfied customers. Standard products may be returned within 30 days of receipt, in good condition and in their original packaging.
Custom-made products are not eligible for return, as they are manufactured specifically according to your measurements and specifications.
To initiate a return, please contact our customer service team with your order number.
