Acoustic curtains are generally made of heavy duty, flame retardant fabrics, specially designed and constructed to absorb sound. They can be used with various track systems to afford greater flexibility than fixed sound absorptive panels.
Flexible Fabric Systems to Absorb Sound
Typically used for recording studios, sound sets, dance, drama and music rehearsal spaces, acoustic curtains can be used in venues ranging from schools to theatres.
Acoustic curtains are primarily intended for sound absorptive applications, as they offer minimal sound transmission loss. But acoustic curtains have a wide variety of applications apart from absorbing sound. They can be used to cover window areas, to divide spaces, or they can be arranged to cover hard or reflective surfaces, which allows an element of acoustic ‘tuning’ within a room. Specialty Theatre generally manufactures acoustic curtains from either wool serge or velvet velour, as the heavier nature of these fabrics provides the best acoustic results. Track selection is based on the relevant application and is dependent on curtain size, weight and arrangement.

Maintenance: Acoustic curtain fabric can only be cleaned with a vacuum cleaner or soft brush. Wet cleaning of flame retardant material will compromise the fire resistance and must be avoided.
Dry cleaning is possible with care, but only as a last resort. The track should be periodically cleaned to keep surfaces clear of dust and grease, joint alignment should be checked and fixings tightened if necessary. Worn or broken parts should be replaced.
