Case study - Black Acoustic Insulation for Semi-Exposed Ceilings
Black Acoustic Insulation for Semi-Exposed Ceilings
Application Overview
Commercial buildings often incorporate hard surfaced internal linings such as concrete, glass, steel and timber. These materials are commonly featured in modern architecture and play a key role in achieving interior aesthetic design goals.
Hard surfaced linings however can be problematic when room acoustics aren’t managed correctly. Hard surfaced linings reflect sound waves, and when these materials are prominent they can cause excessive noise reverberation making a space uncomfortable and unappealing. The design of a commercial building needs to go beyond aesthetics and incorporate acoustic engineering to ensure the space feels and sounds comfortable.
Semi-exposed ceiling systems that incorporate Martini Absorb HD Black can provide architects and acoustic engineers with a solution that achieves modern aesthetic design goals and acoustic performance targets.

Semi-exposed ceiling with black acoustic soffit insulation
The Martini Absorb HD Black can be installed directly to the concrete soffit or installed directly behind the ceiling system.
The Martini Absorb HD Black creates a backdrop for the semi‑exposed ceiling and achieves high performance sound absorption across a range of frequencies.

Acoustic Performance
Martini Absorb HD Black is manufactured with a specific blend of very fine low denier fibres. Fibre diameter is significant for acoustic insulation products. Air trapped between fibres reacts with sound energy and is converted to heat. The more fibres per square metre of insulation, the greater the surface area for absorption, which translates into superior acoustic performance.
