Speedline AAH02B Acoustic Hanger – 70mm - Box of 100

70mm Speedline AAH02B Acoustic Hanger is a specialised anti-vibration component designed for use with the Metal Furring (MF) Ceiling System. Its entire purpose is to prevent sound energy (particularly impact noise and vibration) from transferring directly from the structural floor/ceiling above into the finished plasterboard ceiling below. Unlike the rigid SSL06 angle and AMF12B cleat, this hanger is resilient. It incorporates a flexible or damping element (often a synthetic rubber, neoprene, or spring-steel isolator) to de-couple the metal framework from the structural soffit. This interruption breaks the path of vibration, significantly improving sound insulation.

The 70mm figure refers to the increased drop or stand-off distance provided by the hanger itself. This height, combined with the thickness of the MF channels and the resulting plasterboard lining, creates a necessary cavity depth for maximum acoustic benefit (often requiring mineral wool insulation placed in the plenum). Due to its robust construction, the AAH02B is certified to safely support the full specified load of the MF system, including double layers of plasterboard and dense acoustic mineral wool placed within the deeper cavity.

Function within the System

The AAH02B is selected when project specifications call for the highest possible reduction in noise transfer:

• Enhanced Decoupling: The resilient element ensures the metal ceiling framework is not rigidly connected to the structural ceiling, which is key to preventing sound flanking paths.
• Deeper Cavity: The 70mm size facilitates a significantly deeper air cavity (plenum) than the 35mm version, which, when combined with mineral wool insulation, allows the ceiling system to absorb and dampen a wider range of sound frequencies, particularly the challenging, long-wavelength low frequencies (e.g., heavy bass or deep impact).
• Mounting: The component is designed for straightforward fixing to the structural soffit and incorporates a specific fitting point for the SSMF7 Primary Channel on its lower end.
