Technical Specifications

Technical information for architects, acoustic consultants, designers, contractors and specifiers considering Ace Acoustics site-fabricated stretch-fabric acoustic wall systems, acoustic panels and ceiling systems.

Specification Data by Product Type

Verified technical information for the site-fabricated stretch-fabric acoustic wall system — Ace Acoustics' principal offering — alongside acoustic panel and ceiling systems.

Principal System

Site-Fabricated Stretch Fabric Acoustic Wall System

The Whisper Walls® system is constructed on site to suit the required wall dimensions, rather than manufactured as a prefabricated panel to fixed sizes. It comprises a perimeter and intermediate retention track, an acoustic absorber core, and an acoustically suitable textile facing that is stretched and tucked into the track.

Principal System Depths

12mm

Absorber Class D

23mm

Absorber Class C

27mm

Absorber Class C or Class B (tested configuration dependent)

52mm

Absorber Class A

A 32mm / Absorber Class B configuration is available as an additional specialist option and is confirmed on a project-specific technical basis.

Installation & Design Flexibility

  • Site-fabricated to custom wall and ceiling dimensions
  • Seamless or hairline-jointed finishes, depending on textile width and design
  • Curved and faceted applications
  • Integration around architectural details and building services
  • Project-specific fabric and finish selection

Fire Performance

Euroclass B or Euroclass C, depending on the specified and tested fabric/core configuration. Fire classification is confirmed on a project-specific basis with reference to BS EN 13501-1.

Secondary System

Demountable Acoustic Panels

A demountable, modular acoustic panel option is also available, supplied in 23mm and 43mm depths. This system is secondary to the site-fabricated stretch-fabric wall system and is specified where a demountable installation is preferred.

Acoustic Testing & Classification

Sound absorption performance is measured to BS EN ISO 354 and classified to BS EN ISO 11654, which assigns an Absorber Class of A, B, C or D according to the tested configuration. Absorber Class is a rating derived from this classification standard, not a frequency-by-frequency absorption coefficient.

Room Acoustics — Not Soundproofing

Ace Acoustics acoustic wall and panel systems are internal room-acoustic treatments used for sound absorption, reverberation control, echo reduction and improved speech intelligibility. They are not structural soundproofing or sound-transmission systems.
