ALPHAcoustic-AC.sa is a new series of sound absorbing curtains, primarily designed to absorb more sound than standard decorative curtains. These acoustic curtains are made of sound absorbing regulation 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.
• 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
• Theater STAGE Curtains, School STAGE Curtains
1 Layer of heavy acoustic fabric αw=0.65
2 Layers of heavy acoustic fabric αw=0.80
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.
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-AC.sp 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.
The Sound Reduction Index Rw reaches up to 10 dB for 3 layers according to EN ISO10140-2.
All fabrics can be flame retardant. The track system consists of an aluminum rail track system, which easily moves the sound curtain.
