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.
Verified technical information for the site-fabricated stretch-fabric acoustic wall system — Ace Acoustics' principal offering — alongside acoustic panel and ceiling systems.
Principal 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.
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.
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
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.
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.
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.
Documentation is prepared and issued on a project-specific basis. Contact the technical team to request the information relevant to your specification.
