Mineralised fir wood wool bound with Portland cement. Celenit is a natural and sustainable insulating material, made only with natural materials: wood, Portland cement, marble dust and water. Celenit provides advanced solutions that blend high sound absorption performance with the sustainability and eco-compatibility of a natural product, which is also aesthetically attractive and mechanically resistant.

With their particular surface configuration, wood wool boards are natural sound absorbers. Soundwaves do not bounce from one wall to another, rather they are partly absorbed and dissipated, thus avoiding annoying reverberation.

  • Fire Rated — Group 1S Fire Rating
  • 2400 x 600mm — 25mm
  • Sustainable – Manufactured using fir wood from sustainably managed forests (PEFC™ or FSC® certificate)

Celenit products are not harmful for human health and the environment and the low energy production process creates limited emissions into the atmosphere (ANAB-ICEA and nature plus certificate). It uses recycled materials such as calcium carbonate, which is the residual dust of marble processing (ICEA certificate).

Finally, the raw materials are close to the production establishment (regional material). For all these reasons, CELENIT panels can be used in projects that require building sustainability certificates such as Leed, SBtool, SB100, and Breeam.
