Our felts are made from 100% sheep’s wool.

Our wool is previously treated conferring fireproof, anti-mite and fungicide properties.

The range of wool felt is highly functional, with good insulation properties making it efficient for installation as a building insulation product.

It is a natural product that is both innocuous and pleasant to the touch, which does not require any additional type of protection for handling and installation.

It absorbent capacity, even up to 30% of its weight in water and then to return this to the atmosphere when it is drier, makes it a thermal regulator and enhances environmental comfort.

Our insulating felts are effective, natural solutions to reduce noise levels caused by contact between beams and subsoil. The impact of walking or vibrations, for example, are absorbed by the thickness of the wool felt under the flooring, thus effectively reducing the noise level.
