Acoustic Curtains
ALPHAcoustic-ACu. Reverb
Sound Absorbing Curtain
ALPHAcoustic-ACu. Reverb is a new series of sound absorbing curtains, primarily designed to absorb more sound than standard decorative curtains. These acoustic curtains are made of high sound absorbing fabrics and are ideally used where control of acoustic reflection of glass and ambient light control are required.
The basic choice is a single layer of acoustic fabric. There is a wide range of fabric textures and colours in order to select the right combinations for your project.
In case, there are high demands for increased sound absorption, the acoustic curtains can be made of a double layer of fabric, with an intermediate additional sound-absorbing material which is not visible.
Due to their very good acoustic properties, acoustic curtains can reduce annoying noise reflections and resonant acoustic field, improving acoustic comfort, offering a better acoustic environment.
Ιt is possible to change the light and acoustic conditions of the room with an easy horizontal movement.
Characteristics:
• Excellent Sound Absorption
• Cost effective method of controlling reverberation (Rt)
• Thermal insulation
• Easy installation
• Taylor made designed for high acoustic standards projects
• Reverberation time can be easily adjusted
• Moderate variety of colour and fabric options
• Poor sound insulating effect
• Ambient light control (black-out)
• Theater STAGE Curtains, School STAGE Curtains
Acoustic Properties
1 Layer of heavy acoustic fabric up to αw=0.80
2 Layers of heavy acoustic fabric αw=0.90
3 Layers “NWF” or Velvet +Molton αw=1.00
The above weighted sound absorption coefficients are valid for 100% pleated curtain at a distance of 20 cm from the surface of the room according to EN ISO 11654:1997.
ALPHAcoustic-ACu. Noise
Sound Proofing Curtain
Acoustic curtains are not generally used to stop noise transmission. Nevertheless, in some circumstances, with careful scheduling, acoustic curtains can absorb and reflect unwanted noise. With the interpolation of high mass fabrics/membrane between the external face fabrics, we can achieve acceptable sound insulation values. The effectiveness of such curtains / drapes is dependent on flanking around paths sealing achievement.
ALPHAcoustic-ACu. Noise Acoustic Sound-Proofing Curtains are designed to reflect and absorb sound energy, reduce the noise and improve the room acoustics. Curtains can cover a door or window or divide a room in domestic and commercial applications. Useful also for office separation, quiet zones, think tanks, conference halls etc.
Triple layering of the curtains consists of two parts of special sound absorbing fabrics that enclose a specially designed sound insulating membrane in the middle.
The Sound Reduction Index Rw reaches up to 13 dB for 3 layers, confirmed by independent lab testing.
All fabrics can be flame retardant. The track system consists of an aluminum rail track system, which easily moves the sound curtain.
Hanging Rail System
ALPHAcoustic-ACu. Noise acoustic curtains can be equipped with their corresponding suspension and rolling mechanisms guaranteeing excellent sliding. These mechanisms come from recognized European companies and are selected based on the needs of each application.
- Operating modes: Manual, cord operated or electric remote control.
- Possibility of shaping the rolling rail in a curved track.
- Fitting methods and Hanging rail system are selected on project base.
- They ensure excellent slip.
Our team of acoustic engineers can assist in choosing the acoustic curtain type with the most adequate acoustic properties for your project.

Now we give you the opportunity to cover the glass surfaces with special 
acoustic roller blinds.
For each type of sound-absorbing curtain, official certifications on its acoustic performance are available upon request. Contact us for more information.
