Reduce noise pollution without any construction work—
, with performance measured in an accredited laboratory, up to -28.2 dB.
A custom- soundproof curtain e is only as good as its measured performance: at Nokomis, each model is tested in an accredited laboratory (down to -28.2 dB), and the custom fit ensures complete coverage of the window, with no noise leakage from the sides.
Noise seeps in through even the smallest gaps: a curtain that is too narrow or too short lets in noise and negates some of the measured sound reduction. A custom-made curtain seals these gaps by covering the entire glass surface, including the overhangs.
An effective sound acoustic curtain ation is based on the law of acoustic mass: the denser and heavier the fabric, the more it dampens sound waves. However, a heavy fabric that doesn’t fit properly loses its effectiveness if air—and therefore sound—escapes around the edges. That is why custom-made solutions are not merely a decorative feature at Nokomis, but a technical requirement for effective soundproofing.
- We recommend extending the material several centimeters beyond each side of the window to prevent sound from escaping around the edges
- A height that extends beyond the ledge and down to the floor to reduce low-level leakage
- Eyelets: quick installation, even pleats, good coverage at Track or Curtain pole
- Gathering tape : dense pleats, ideal for making the most of the fabric when hung in front of a window or French door
- Coverage for a standard window, a picture window, or a door, depending on the exact layout of the room
Nokomis measures its soundproof curtains in an accredited laboratory according to a recognized standard, rather than providing uncalibrated decibel figures. The Performance PLUS model achieves a sound reduction of -28.2 dB under these test conditions.
Many sellers post figures without providing evidence. We document both the methodology and the report so that performance is verifiable rather than merely claimed.

A decibel value is meaningful only if it specifies the standard, the laboratory, and the measurement frequency. A single number, without any context or methodology, proves nothing.
Always ask to see the lab report, the standard reference, and the total assembled weight of the fabric (in kg/m²). These three factors distinguish a true “ soundproof curtain ” from a blackout curtain marketed as such.
Three performance levels to suit your needs, ranging from basic acoustic comfort to enhanced noise reduction for highly exposed environments. Each product line combines noise reduction, light blocking, and thermal insulation.
All of our product lines are manufactured in France, custom-made to your specifications, and tested using the same measurement standards. The choice depends on the noise issue to be addressed and the room in question.
- Performance PLUS (braided or satin): up to -28.2 dB, for high noise levels (busy streets, railways, airports); see the noise-reducing curtain 30 dB Performance PLUS
- Performance: -19.7 dB, good balance for a room or office facing that direction
- Comfort: -12 dB, to reduce moderate noise and create a quieter everyday environment
- Thermal benefits: a measured temperature difference of 6 to 8 °C, less heat loss in winter and less heat gain in summer—discover our thermal insulation curtains
- Built-in blackout feature (see our custom blackout curtains : the thick fabric filters out light and makes the room darker

soundproof curtain s are suitable for bedrooms, offices, living rooms, or as room dividers. The choice of fabric and weight depends on the level of noise to be reduced.
For a bedroom facing the street, we recommend the highest sound insulation level (Performance PLUS) to ensure a good night’s sleep. For an office or workspace, the Performance line is often sufficient to achieve a comfortable noise level. Available colors: blue, gray, green, white, and beige, in a velvet or satin finish depending on the material.
soundproof curtain, Acoustic or Noise-Reducing: Clearing Up the Confusion
The terms overlap but do not refer to the same thing. A sound soundproof curtain e (or noise-reducing curtain) reduces noise coming from outside; a purely acoustic curtain primarily reduces internal echoes within a room.
Nokomis It is neither a wall panel, nor studio foam, nor insulation installed during construction. It is a home textile that blocks and dampens outside noise, without the need to install double-pane windows or partitions.
- soundproof curtain / noise reduction: protection against external noise (traffic, neighbors, city)
- acoustic curtain : reduces echo and reverberation inside a room
- Thermal insulation curtain: reduces heat loss and keeps cold air out
- Our products combine these effects into a single, patented multilayer product
- This isn't soundproofing that requires construction work: a solution that doesn't involve a construction site and is reversible in rental properties
How to Choose Your Custom-Made soundproof curtain
The right choice depends on three factors: noise level, the area to be covered, and the mounting method. Start by assessing the actual noise problem, then determine the weight of the fabric and its dimensions.
A curtain that is too small or too lightweight will not deliver on its acoustic promises. It’s better to choose the right density for your noise exposure than to rely solely on aesthetics.
- Identify the source: traffic, a neighbor, outside noise, or a partition
- Choose the product line based on your target decibel level (Comfort, Performance, Performance PLUS)
- Select the fabric and color (velvet, satin, twill) and the eyelet finish or Gathering tape
- Allow for side overhang and a generous height to ensure soundproofing
- Check compatibility with a Track or a Curtain pole, or choose our custom-built Track 4400RM
Measure the total width to be covered, including overhangs, and the height from the mounting point to the floor. Add some extra width on the sides to block sound from escaping.
For best results, the width of the fabric should exceed that of the window, and the curtain should extend past the window sill. Our configurator guides you step by step, with finishing tips tailored to your Track or Curtain pole.
- Width: Measure Curtain pole or Track, then add the overhang on each side
- Height: from the attachment point to the floor for full coverage
- Note the type of window (single-pane, picture window, door) to customize the design

Performance comes from the fabric's weight and structure, not from a simple lining added to the surface.
An effective curtain relies on a thick, dense fabric, whose total assembled weight is measured in g/m². Our product lines are designed around textile microfilaments that increase the mass per square meter, in accordance with the law of acoustic mass. The heavier and more compact the material, the greater the reduction in outside noise. The quality of the construction is just as important as the raw material: seams, pleats, and drape all influence how the curtain contacts the wall and window.
- High-density microfilament fabric, measured in g/m² rather than estimated by feel
- Built-in lining on the 3-in-1 lines to provide soundproofing, thermal insulation, and light-blocking properties
- A braided or satin finish, depending on the desired visual appearance and level of absorbency
A curtain primarily works by blocking outside noise, but it also helps absorb some sound within the room.
Sound blocking reduces the noise coming in from the street or the adjacent room, as measured in dB in an accredited laboratory. Sound absorption, on the other hand, reduces reverberation inside: voices carry less, and echoes are diminished in a large, empty room. A living room with hard surfaces and large windows benefits from both effects. Our reports distinguish between these two effects to avoid citing unsubstantiated figures that the brand refuses to disclose.
- Sound insulation: less noise from outside, as measured by a standardized test
- Absorption: Less echo and reverberation in the treated room
- The perceived comfort is a combination of both, depending on the layout of the home
soundproof curtain s reduce noise coming from outside, such as traffic or neighbors. acoustic curtain s primarily correct echo and reverberation inside a room. Nokomis models combine both effects in a multilayer fabric.
The noise reduction varies by model: up to -28.2 dB for Performance PLUS, -19.7 dB for Performance, and -12 dB for Comfort. These values are measured in an accredited laboratory in accordance with the NBN EN ISO 10140-2:2010 standard and are not simply claimed without evidence.
Yes. A curtain that is too narrow or too short allows sound to escape around the edges, which degrades the measured performance. A custom-made curtain ensures full coverage of the window with side overhang, which is a technical requirement for soundproofing.
The curtains are tested in a BELAC/Peutz-accredited laboratory (ISO 17025) in accordance with the NBN EN ISO 10140-2:2010 standard, as documented in report No. A-2020LAB-060-I766-44092_E. The technology is patented (No. to be confirmed).
Yes, the fabric's density limits heat loss: our measurements show a difference of 6 to 8 °C. These models also provide blackout capabilities by filtering light to make the room darker.
The price reflects a high-density fabric made in France, custom tailoring to your measurements, and performance tested in a laboratory. A standard, inexpensive curtain does not guarantee full coverage or the advertised decibel levels.
Enter your measurements in the configurator, choose the line and finish, then confirm your purchase online. The price is displayed based on the surface area and options, in euros or in your country’s currency. Each order then triggers the production process tailored to your measurements.
The garments are manufactured in France using fabric designed and tested in an accredited laboratory. This process ensures quality control at every stage, from the raw material to the finished product. You’re not dealing with a middleman: production is handled in-house.
Yes, it reduces outside noise and creates a quieter, more restful environment for sleep. The effect depends on the model you choose and on installing it as close to the window as possible. For a bedroom facing the street, a high-density fabric makes a noticeable difference.
