ProSonic Acoustic Curtains are designed to provide a degree of sound absorption within the space in which they are used. 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:

Tie Tops

25mm wide cotton tape ties can be sewn into the top of the curtains. This provides a quick and easy method for fixing curtains to rails or curtain rods. We can mark the centre section with a coloured tie if required.

Tab Hooks

Metal hooks sewn onto a cotton tape. An ideal fixing for most medium to heavy curtains. The hooks are very strong and have the added benefit of not being seen from the front.

Ideal for when the curtain needs to hang below the eye of the runner on the track.

Curtain bottoms

Usually we add a chain weighted base which allows the curtains to hang correctly and move smoothly during opening and closing but pockets for pipes are also available.


The sides are continously hemmed and can also be fitted with velcro tape to help join smaller sections together.


Standard units are supplied unlined but lining options are available.


Standard units are supplied to 50% fullness. This means the degree of pleating. At 50% this means the curtains are one and a half times the width of the track.
