Acoustic wall curtains are typically made of heavy duty, flame retardant, acoustically absorbent fabrics and 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 and in venues ranging from schools to theatres. Acoustic wall curtains can be used to cover window areas, to divide spaces or arranged to cover hard or reflective surfaces which allows an element of acoustic ‘tuning’ within a room. Acoustic wall curtains are manufactured from either wool serge or velvet velour, as the heavier nature of these fabrics provide the best acoustic results. Track selection is based on application, dependent on curtain size/weight and arrangement. Acoustic curtains are primarily intended for sound absorptive applications, as they offer minimal sound transmission loss.

Stated absorption coefficients based on unlined curtains manufactured to 50% fullness
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.
