Soundproof curtain: is it really effective against noise?
A curtain designed to limit sound transmission can help attenuate noise passing through the covered opening. Kurtens states up to 22 dB under optimal installation and test conditions. Results in your home depend on frequencies, coverage and installation.
Sound absorption and sound insulation address different needs. Fabric weight alone cannot determine a curtain’s performance.
Why so much doubt about the effectiveness of acoustic curtains?
Sound insulation aims to limit noise transmission between two spaces. Absorption treats reflections and reverberation within a room. Product names are not enough: compare documented performance that matches your needs.

How to compare soundproof curtains
Compare fabric construction and acoustic results together with their measurement conditions. Fabric weight alone does not give attenuation in dB. Kurtens fabric has 3 layers and weighs 620 g/m²; its stated attenuation is up to 22 dB under optimal installation and test conditions.
Absorption reduces sound reflections and reverberation within a room. Sound insulation aims to limit noise transmission between spaces. An attenuation value depends on frequencies and measurement conditions; the stated 22 dB is not a guaranteed reduction of every noise in your home.
what decibel attenuation really means
| Feature | Product specification |
|---|---|
| Construction | 3 technical layers |
| Fabric weight | 620 g/m² |
| Sound attenuation | Up to 22 dB* |
| Thermal gain | Up to 7 °C measured in a laboratory |
| Blackout | 100 % |
*Stated attenuation under optimal installation and test conditions. Results depend on the noise, coverage and installation; they are not guaranteed in every home.
| Criterion | What to check |
|---|---|
| Need | Outside noise or reverberation inside the room |
| Fabric | Composition and construction; weight alone does not give the dB rating |
| Acoustic measurement | Protocol, frequencies and setup when comparing results |
| Dimensions | Coverage of the opening, side allowances and overlap between panels |
| Mounting | Supports and curtain pole suitable for the total curtain weight |
Is an acoustic curtain enough to no longer hear the street?
A curtain in front of a window can help attenuate airborne noise passing through that opening: voices, traffic or construction work. It does not address transmission through walls, floors and the building structure. Results depend on the noise and installation; 22 dB alone cannot predict the final sound level of a construction site.
A curtain does not block every noise. The stated attenuation of up to 22 dB does not guarantee the same result for every frequency or home. Structure-borne noise, such as footsteps upstairs, requires treatment suited to its transmission path.
sound insulation solutions without major work
Is a custom-made acoustic curtain necessary, or is a standard size sufficient?
A standard size can be suitable if it covers the opening properly with the necessary overlap. Made-to-measure allows dimensions to be adapted when the available sizes do not fit; it does not guarantee better insulation on its own.
Check the seals and window coverage, then choose mounting suitable for the curtain’s weight. An existing pole can only be reused if its supports and load capacity are suitable; installation without drilling is not guaranteed.
Can an acoustic curtain and double glazing be combined?
A suitable curtain and window seals in good condition can complement each other. First check where the noise travels. A curtain does not replace treatment of other transmission paths; results depend on the window and installation.
The Kurtens soundproof curtain uses the same fabric as the 3-in-1: 3 layers, 620 g/m², 100 % blackout and a thermal gain of up to 7 °C measured in a laboratory. These features do not automatically apply to every thick curtain.

Is a soundproof curtain really effective?
A curtain designed to limit sound transmission can help attenuate noise passing through the covered opening. Kurtens states up to 22 dB under optimal installation and test conditions. Results in your home depend on frequencies, coverage and installation.
How many decibels can an acoustic curtain reduce?
Compare fabric construction and acoustic results together with their measurement conditions. Fabric weight alone does not give attenuation in dB. Kurtens fabric has 3 layers and weighs 620 g/m²; its stated attenuation is up to 22 dB under optimal installation and test conditions.

It does not address transmission through walls, floors and the building structure. Results depend on the noise and installation; 22 dB alone cannot predict the final sound level of a construction site.
What is the difference between a thick curtain and a true acoustic curtain?
Sound absorption and sound insulation address different needs. Fabric weight alone cannot determine a curtain’s performance.
Compare fabric construction and acoustic results together with their measurement conditions. Fabric weight alone does not give attenuation in dB. Kurtens fabric has 3 layers and weighs 620 g/m²; its stated attenuation is up to 22 dB under optimal installation and test conditions.
Does the acoustic curtain work with an open window?
To limit outside noise, keep the window closed and the curtain drawn across the opening. Check the paths sound can take around the installation. The stated 22 dB does not automatically apply to a different setup, particularly with the window open.
Is a custom-made acoustic curtain necessary, or is a standard size sufficient?
A standard size can be suitable if it covers the opening properly with the necessary overlap. Made-to-measure allows dimensions to be adapted when the available sizes do not fit; it does not guarantee better insulation on its own.
Can an acoustic curtain and double glazing be combined?
A suitable curtain and window seals in good condition can complement each other. First check where the noise travels. A curtain does not replace treatment of other transmission paths; results depend on the window and installation.
What fabric weight makes a curtain soundproof?
Compare fabric construction and acoustic results together with their measurement conditions. Fabric weight alone does not give attenuation in dB. Kurtens fabric has 3 layers and weighs 620 g/m²; its stated attenuation is up to 22 dB under optimal installation and test conditions.
What to remember before choosing
Check acoustic results and measurement conditions, fabric construction, coverage and mounting. A standard size can work if it properly covers the opening; made-to-measure dimensions help when the available sizes do not fit.
