The material

What is
Absora-sheet?

Absora-sheet is essentially a high-strength sheet – a groundbreaking material for lightweight construction, acoustics, and filtration. Thanks to its lateral micro-perforation, it not only absorbs sound and vibrations with high efficiency but also actively smooths air and fluid flows. A true technological leap for the most demanding applications, achieved entirely without conventional, bulky insulation materials.

Sound absorption compared

Absora-sheet absorbs broadband — consistently high across the entire frequency spectrum, where conventional absorbers only work in narrow bands.

Acoustics & flow

Sound, vibration & flow smoothing

Absora-sheet absorbs sound and vibrations across a wide frequency range. In the low-frequency range, the sheet metal is 50-80% more effective than conventional absorbers made of rock wool or foam. At the same time, the intelligent perforation ensures that incoming air currents are smoothed in a targeted manner.

02

Lightweight construction

Groundbreaking for construction

The material offers extremely high rigidity at a very low weight. Absora-sheet is 60-80% lighter than conventional rock wool constructions. It acts as a completely self-supporting sheet, eliminating the need for heavy substructures.

03

Filtration & economy

Versatile, clean & affordable

Besides its acoustic properties and lightweight construction, micro-perforated sheet metal is ideally suited for demanding filtration tasks. It is over 50% cheaper to purchase, fully recyclable, and, as an absolutely fibre-free material, avoids any hygiene problems.
