A unique absorber that has been specially developed to withstand rough treatment. The absorber is covered with fibreglass cloth on the visible surfaces and has very high surface strength. This makes it highly resistant to impacts and, for example, ball games. The absorber has very good sound absorption and is highly sound-absorbing. Suitable for use in particularly exposed environments such as schools, youth clubs, kindergartens, public buildings, car parks, etc.

The core of the absorber consists of compressed glass wool. The visible surfaces are covered with coloured fibreglass cloth, which is also wrapped around the sides and attached to the back of the sheet. This is to prevent it from fraying and being damaged. The back is covered with transparent fibre cloth. The edges are thoroughly sealed.

The panel is installed/glued directly to the ceiling or wall. Attached with glue. You need 1 cartridge for 2 m2 of absorbent.

Sizes. Standard sizes and colours in stock. Special sizes and the colour black grey (matte black) can be ordered.

Colours. The standard colours of the absorber are white, light grey and black grey. The closest colour code for light grey is RAL 7038, the closest colour code for white is RAL 9003 and for black grey RAL 7021.

The product is impact resistant. The absorber is tested for impact resistance in class 1A in accordance with EN13964, annex D and DIN 18032:2018-11. This is the best possible for this type of product/material.

The product is M1 certified
This means that the product has been tested and fulfils the strictest international requirements for emissions and non-use of toxic components. There are special requirements for acoustic products that must be met to obtain M1 certification.

Insulating properties. The absorbers have very good insulation properties. Laboratory tested in accordance with current regulations. Thermal thermal conductivity / Lambda value = 0.033W/(m-K). Thermal heat resistance = 1.191 (m2-K)/W.

EPD (Environmental Product Declaration). The product has completed the LCA (Life Cycle Assessment) report and received an EPD (Environmental Product Declaration) certificate.

Cleaning and maintenance. The panel has a surface that allows for dusting, vacuuming and gentle washing with a slightly damp cloth. If the disc is painted over, it will lose its properties.
