A custom-made Kurtens soundproof curtain reduces outside noise by up to 22 dB*. Designed for windows, French windows, and bay windows of exact dimensions, each curtain is made to order to eliminate lateral gaps that reduce soundproofing effectiveness. Available in 7 colors.

*Performance achieved under optimal installation and testing conditions.
The decibel scale is logarithmic: a 10 dB reduction halves the perceived sound volume. With 22 dB of attenuation, the Kurtens soundproof curtain significantly transforms your sound environment.
Here are some concrete examples:
A city street at 70-75 dB becomes comparable to a quiet office at 50 dB. The noise of heavy traffic at 80 dB is reduced to the level of a conversation.
Night-time disturbances that disrupt sleep are attenuated to restore an environment conducive to rest. This level of attenuation is achieved thanks to a high-density fabric with a high surface mass, combined with custom installation without lateral play.
A standard noise-reducing curtain loses up to 40% of its effectiveness due to side gaps and floor clearance. Sound, like air, always finds the path of least resistance.
At Kurtens, each curtain is custom-made to the exact dimensions of your window or door, with a recommended lateral overlap of 15 to 20 cm on each side to eliminate acoustic bridges. A floor-to-ceiling or window-to-ceiling height depending on your configuration.
A drop of 2 to 3 cm to the floor to close the bottom junction. The result: the 22 dB attenuation is achieved over the entire surface, not just in the center of the curtain.
The WHO ranks environmental noise as the second biggest health risk factor in Europe, after air pollution. To learn more, read our article apartment soundproofing without renovation.

This principle is known in acoustics as the mass law: at the same frequency, doubling the surface mass of a material increases its insulation by approximately 6 dB. To understand the difference between blocking and absorbing sound, consult our guide soundproof vs. acoustic curtains.
Noise reduction performance by fabric density
| Category | Density | Heat gain | Sound attenuation | Concealment |
|---|---|---|---|---|
| Standard thick curtain | 150-300 gsm | 1 to 2°C | 5 to 7 dB | 40 to 70% |
| Mid-range | 300 to 500 gsm | 2 to 4 °C | 12 to 18 dB | 70 to 90% |
| High performance | 500+ gsm | 5 to 7°C | 18 to 25 dB | 95 to 100% |
| Kurtens | 620 gsm | Up to 7°C* | 22 dB* | 100%* |

Frequently Asked Questions
Do noise-reducing curtains really work?
Yes, provided they are correctly sized and installed. A custom-made Kurtens soundproofing curtain reduces noise by up to 22 dB*, which means dividing the perceived sound volume by more than two. The effectiveness primarily depends on the fabric's mass, the absence of a lateral gap, and the installation height.

What is the difference between a noise-reducing curtain and a soundproof curtain?
Both terms refer to the same function: reducing noise entering through windows and doors. The term "soundproof" is more technical, while "noise-reducing" is more common. Our curtains combine both characteristics.
Is a custom-made noise-reducing curtain more effective than a standard curtain?
Yes, the gaps in a standard curtain (side play, floor clearance) reduce efficiency by 30 to 40%. Custom-made eliminates these acoustic bridges and guarantees up to 22 dB of attenuation over the entire surface. Under optimal installation and testing conditions.
How long will it take to receive my custom-made noise-reducing curtain?
Each custom curtain is made to order in the workshop. Manufacturing time is 5 to 7 working days, and delivery time is 5 to 10 working days.
Is it possible to have a curtain that is both noise-reducing and blackout?
Yes, our range combines all three performances: total blackout, thermal insulation, and noise reduction.
In what colours is the noise-reducing curtain available?
The range is available in 7 colors: Grey, Off-White, Cream, Mint Green, Green, Lilac, and Blue. All colors are available in all custom sizes with our various types of mounting hardware.
How to reduce noise in an apartment without renovations?
The most effective solution without any work is a noise-reducing curtain installed in front of the windows, the primary source of outdoor noise in a dwelling. A high-density noise-reducing curtain like those from Kurtens reduces noise by up to 22 dB (under optimal test conditions), which divides the perceived sound volume by four. Supplement this with new weatherstripping on windows and the front door to eliminate occasional sound leaks. Installing a custom noise-reducing curtain takes only a few minutes, with no tools required.
Can a noise-reducing curtain be combined with other insulation solutions?
Yes, and it is recommended for optimal results. The most effective combination without major work: custom soundproofing curtains for windows + new weatherstripping + thick carpet on the floor. Each solution addresses a different type of noise, and the combined result significantly surpasses each solution alone. Kurtens curtains also provide thermal insulation (up to 7°C) and total blackout, which avoids the need for multiple pieces of equipment.
