The Whisperwool construction
soft overlayer
stable core

Pure sheep's wool in combination with an especially developed natural bandage fibre forms the stable core of Whisperwool. Exactly this hard, but permeable core provides for the sound-absorbent effect (αw up to 0.9).


The overlayer of the Whisperwool panels exists of an optically very attractive woollen felt and strongly scores pounts with it in the areas Interior design and sustainability.


Whisperwool plates have a thickness of 12 – 14 mm with a dimension of 900 x 900 mm and with a weight of 3,000 g. By the procedure "Lanaforming" Whisperwool can be also used on irregular substructures (like curved covers).

The Whisperwool colours

Topically we offer Whisperwool in three natural tones:

anthracite, silver-grey and natural-white.
