ACOUSTIC CURTAINS  


 

 

 


We design the Acoustic Curtains to provide a degree of sound absorption within the space in which they are used. Noise levels can be typically reduced by as much as 20 dB(A) with a properly designed curtain enclosure Often used in performing arts spaces they not only provide a variable acoustic environment for different applications but control excessive reverberation in halls with very reflective surfaces.

All material is chemically treated to create a DFR (Durably Flame Retardant) fabric that will withstand a number of dry cleanings. This meets the requirements of BS5867: Part 2: B which is the British Standard for flame retardant fabrics used for the manufacture of curtains.

The degree of sound absorption depends on the weight of the fabric used, the depth between the curtain and the wall and the degree of pleating.

We have three grades:
