Description
ProSonic Acoustic Curtains | High Acoustic Absorption and Sound Control
ProSonic Acoustic Curtains are engineered to deliver high-performance sound absorption and reverberation control in multi-use spaces. Designed primarily for performing arts environments, educational facilities, and public spaces, these acoustic drapes provide a flexible, variable acoustic solution to control excessive echo caused by highly reflective hard surfaces.
Key Applications and Uses
- Educational Facilities: School halls, drama studios, and lecture spaces.
- Performing Arts: Dance studios, theatres, and music practice rooms.
- Community Spaces: Village halls, community hubs, and multi-purpose centers.
- Commercial & Office: Corporate meeting rooms, conference spaces, and boardrooms.
Benefits and Advantages
- High Sound Absorption: Effectively dampens internal room reflections and echo.
- Bespoke Manufacture: Custom-made to order to fit exact structural dimensions.
- Cost-Effective System: Affordable alternative to rigid architectural wall panels.
- Highly Versatile: Easily drawn or retracted to dynamically change room acoustics.
- Inherently Fire Rated: Maximum safety standard compliance for public assembly spaces.
Certified Fire Resistance and Safety Standards
All ProSonic acoustic curtain fabrics are manufactured using IFR (Inherently Flame Retardant) materials.
- Certified toBS5867: Part 2: Type B, the standard for flame-retardant fabrics used in commercial and public curtains.
- Permanent Protection: Unlike chemically treated fabrics, IFR textiles feature permanent fire resistance that will not degrade, wash out, or diminish over time.
Material Specification and Fabric Grades
The overall degree of sound absorption depends on three physical factors: the fabric weight grade, the depth of the air gap between the curtain and the wall, and the percentage of fullness or pleating.

Standard Options for Curtain Tops
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 acoustic 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 acoustic curtains. The hooks are very strong and have the added benefit of not being seen from the front.

Split / Solid Rings
Either 25mm split rings or large 55mm diameter solid rings to the tops. (We can also do 11mm or 40mm diameter eyelets that are punched into the fabric. The larger ones can be used with a suitable diameter curtain pole through them).
Metal Dog Clips
Ideal for when the acoustic curtain needs to hang below the eye of the runner on the track.
Standard Options for Curtain Bottoms
Chains/Pipes: Option to add a chain weighted base which allows the acoustic curtains to hang correctly and move smoothly during opening and closing is available but pockets for pipes are also an option.
Sides: The sides are continuously hemmed and can also be fitted with velcro tape to help join smaller sections together.
Linings: Standard acoustic curtains are supplied unlined but lining options are available.
Fullness: Standard acoustic curtains are supplied as standard to 50% fullness. This means the degree of visual ‘pleating’ effect when open. At 50% this means the acoustic curtains are one and a half times the width of the track.
Tracks: As standard we rely on the customer to provide the mounting system but for larger more complex projects we can supply professional grade industrial tracks with either manual or motorised operation.
If acoustic absorption is not required we can also offer a lighter weight 260g/m2 blackout fabric.
